EVPN Advertisement (expose method ``vrf``)
|
||||
++++++++++++++++++++++++++++++++++++++++++
|
||||
|
||||
When using expose method ``vrf``, the OVN BGP Agent is in charge of triggering
|
||||
FRR (IP routing protocol suite for Linux which includes protocol daemons for
|
||||
BGP, OSPF, RIP, among others) to advertise/withdraw directly connected and
|
||||
kernel routes via BGP.
|
||||
|
||||
To do that, when the agent starts, it will search for all provider networks
|
||||
and configure them.
|
||||
|
||||
In order to expose a provider network, each provider network must match these
|
||||
criteria:
|
||||
|
||||
- The provider network can be matched to the bridge mappings as defined in the
|
||||
running OpenVSwitch instance (e.g. ``ovn-bridge-mappings="physnet1:br-ex"``)
|
||||
|
||||
- The provider network has been configured by an admin with at least a ``vni``,
|
||||
and the vpn type has been configured too with value ``l3``.
|
||||
|
||||
For example (when using the OVN tools):
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ ovn-nbctl set logical-switch neutron-cd5d6fa7-3ed7-452b-8ce9-1490e2d377c8 external_ids:"neutron_bgpvpn\:type"=l3
|
||||
$ ovn-nbctl set logical-switch neutron-cd5d6fa7-3ed7-452b-8ce9-1490e2d377c8 external_ids:"neutron_bgpvpn\:vni"=100
|
||||
$ ovn-nbctl list logical-switch | less
|
||||
...
|
||||
external_ids : {.. "neutron_bgpvpn:type"=l3, "neutron_bgpvpn:vni"="1001" ..}
|
||||
name : neutron-cd5d6fa7-3ed7-452b-8ce9-1490e2d377c8
|
||||
...
|
||||
|
||||
It is also possible to configure this using the Neutron BGP VPN API.
|
||||
|
||||
Initialization sequence per VRF
|
||||
'''''''''''''''''''''''''''''''
|
||||
|
||||
Once the networks have been initialized, the driver waits for the first ip to be
|
||||
exposed, before actually exposing the VRF on the host.
|
||||
|
||||
Once a VRF is exposed on the host, the following will be done (per VRF):
|
||||
|
||||
1. Create EVPN related devices
|
||||
|
||||
- Create VRF device, using the VNI number as name suffix: vrf-1001
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ ip link add vrf-1001 type vrf table 1001
|
||||
|
||||
- Create the VXLAN device, using the VNI number as the vxlan id, as well as
|
||||
for the name suffix: vxlan-1001
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ ip link add vxlan-1001 type vxlan id 1001 dstport 4789 local LOOPBACK_IP nolearning
|
||||
|
||||
- Create the Bridge device, where the vxlan device is connected, and
|
||||
associate it to the created vrf, also using the VNI number as name suffix:
|
||||
br-1001
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ ip link add name br-1001 type bridge stp_state 0
|
||||
$ ip link set br-1001 master vrf-1001
|
||||
$ ip link set vxlan-1001 master br-1001
|
||||
|
||||
2. Reconfigure local FRR instance (``frr.conf``) to ensure the new VRF is
|
||||
exposed. To do that it uses ``vtysh shell``. It connects to the existing
|
||||
FRR socket (--vty_socket option) and executes the next commands, passing
|
||||
them through a file (-c FILE_NAME option):
|
||||
|
||||
.. code-block:: jinja
|
||||
|
||||
vrf {{ vrf_name }}
|
||||
vni {{ vni }}
|
||||
exit-vrf
|
||||
router bgp {{ bgp_as }} vrf {{ vrf_name }}
|
||||
bgp router-id {{ bgp_router_id }}
|
||||

|
||||
redistribute connected
|
||||
redistribute kernel
|
||||
exit-address-family
|
||||
|
||||

|
||||
redistribute connected
|
||||
redistribute kernel
|
||||
exit-address-family
|
||||
address-family l2vpn evpn
|
||||
advertise ipv4 unicast
|
||||
advertise ipv6 unicast
|
||||
rd {{ local_ip }}:{{ vni }}
|
||||
exit-address-family
|
||||
|
||||
3. Connect EVPN to OVN overlay so that traffic can be redirected from the node
|
||||
to the OVN virtual networking. It needs to connect the VRF to the OVS
|
||||
provider bridge:
|
||||
|
||||
- Create a veth device, that will be used for routing between the vrf and
|
||||
OVN, using the uuid of the localnet port in the logical-switch-port table
|
||||
and connect it to ovs (in this example the uuid of the localnet port is
|
||||
``12345678-1234-1234-1234-123456789012``, and the first 11 chars will
|
||||
be used in the interface name):
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ ip link add name vrf12345678-12 type veth peer name ovs12345678-12
|
||||
$ ovs-vsctl add-port br-ex ovs12345678-12
|
||||
$ ip link set up dev ovs12345678-12
|
||||
|
||||
- For EVPN l3 mode (only supported mode currently), it will attach the vrf
|
||||
side to the vrf:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ ip link set vrf12345678-12 master vrf-1001
|
||||
$ ip link set up dev vrf12345678-12
|
||||
|
||||
And it will add routing IPs on the veth interface, so the kernel is able
|
||||
to do L3 routing within the VRF. By default it will add a 169.254.x.x
|
||||
address based on the VNI/VLAN.
|
||||
|
||||
If possible it will use the dhcp options to determine if it can use an
|
||||
actually configured router ip address, in addition to the 169.254.x.x
|
||||
address:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ ip address add 10.0.0.1/32 dev vrf12345678-12 # router option from dhcp opts
|
||||
$ ip address add 169.254.0.123/32 dev vrf12345678-12 # generated 169.254.x.x address for vlan 123
|
||||
$ ip -6 address add fd53:d91e:400:7f17::7b/128 dev vrf12345678-12 # generated ipv6 address for vlan 123
|
||||
|
||||
4. Add needed OVS flows into the OVS provider bridge (e.g., br-ex) to redirect
|
||||
the traffic back from OVN to the proper VRF, based on the subnet CIDR and
|
||||
the router gateway port MAC address.
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ ovs-ofctl add-flow br-ex cookie=0x3e7,priority=900,ip,in_port=<OVN_PATCH_PORT_ID>,actions=mod_dl_dst:VETH|VLAN_MAC,NORMAL
|
||||
|
||||
5. If ``CONF.anycast_evpn_gateway_mode`` is enabled, it will make sure that the
|
||||
mac address on the vrf12345678-12 interface is equal on all nodes, using the
|
||||
VLAN id and VNI id as an offset while generating a MAC address.
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ ip link set address 02:00:03:e7:00:7b dev vrf12345678-12 # generated mac for vni 1001 and vlan 123
|
||||
|
||||
# Replace link local address and update to generated vlan mac (used for ipv6 router advertisements)
|
||||
$ ip -6 address del <some fe80::/10 address> dev vrf12345678-12
|
||||
$ ip -6 address add fe80::200:3e7:65/64 dev vrf12345678-12
|
||||
|
||||
6. If IPv6 subnets are defined (checked in dhcp opts once again), then configure
|
||||
FRR to handle neighbor discovery (and do router advertisements for us)
|
||||
|
||||
.. code-block:: jinja
|
||||
|
||||
interface {{ vrf_intf }}
|
||||
{% if is_dhcpv6 %}
|
||||
ipv6 nd managed-config-flag
|
||||
{% endif %}
|
||||
{% for server in dns_servers %}
|
||||
ipv6 nd rdnss {{ server }}
|
||||
{% endfor %}
|
||||
ipv6 nd prefix {{ prefix }}
|
||||
no ipv6 nd suppress-ra
|
||||
exit
|
||||
|
||||
7. Then, finally, add the routes to expose to the VRF, since we use full
|
||||
kernel routing in this VRF, we also expose the MAC address that belongs
|
||||
to this route, so we do not rely on ARP proxies in OVN.
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ ip route add 10.0.0.5/32 dev vrf12345678-12
|
||||
$ ip route show table 1001 | grep veth
|
||||
local 10.0.0.1 dev vrf12345678-12 proto kernel scope host src 10.0.0.1
|
||||
10.0.0.5 dev vrf12345678-12 scope link
|
||||
local 169.254.0.123 dev vrf12345678-12 proto kernel scope host src 169.254.0.123
|
||||
|
||||
$ ip neigh add 10.0.0.5 dev vrf12345678-12 lladdr fa:16:3e:7d:50:ad nud permanent
|
||||
$ ip neigh show vrf vrf-100 | grep veth
|
||||
10.0.0.5 dev vrf12345678-12 lladdr fa:16:3e:7d:50:ad PERMANENT
|
||||
fe80::f816:3eff:fe7d:50ad dev vrf12345678-12 lladdr fa:16:3e:7d:50:ad STALE
|
||||
|
||||
|
||||
.. note::
|
||||
|
||||
The VRF is not associated to one OpenStack tenant, but can be mixed with
|
||||
other provider networks too. When using VLAN provider networks, one can
|
||||
connect multiple networks to the same VNI, effectively placing them in the
|
||||
same VRF, routed and handled through kernel and FRR.
|
||||
|
||||
.. note::
|
||||
As we also want to be able to expose VM connected to tenant networks
|
||||
(when ``expose_tenant_networks`` or ``expose_ipv6_gua_tenant_networks``
|
||||
configuration options are enabled), there is a need to expose the Neutron
|
||||
router gateway port (cr-lrp on OVN) so that the traffic to VMs in tenant
|
||||
networks is injected into OVN overlay through the node that is hosting
|
||||
that port.

|

On Host-2, the IPs of both the external router gateway port (GW, ``172.16.2.12``),
|
||||
as well as the subnet it exposes (``192.168.0.0/24``) gets added to the
|
||||
routing table of the vrf (``vrf-1001``). Also any instance that is attached
|
||||
directly on a provider network is added to the routing table.
|
||||
|
||||
Then FRR is utilized to expose this vrf through BGP/EVPN. Routes from other nodes
|
||||
are imported and added as an VXLAN route, pointing to the bridge (``br-1001``).
|
||||
|
||||
This allows the external route to reach the internal VM, possibly routed
|
||||
through the host that is hosting the router gateway port.

Configure provider networks
|
||||
---------------------------
|
||||
|
||||
This section assumes, that you've already configured OVN, and applied the correct bridge-mappings
|
||||
on the hosts themselves, see `Neutron documentation regarding provider networks. <https://docs.openstack.org/neutron/latest/admin/ovn/refarch/provider-networks.html>`_
|
||||
|
||||
First, create your provider network through neutron
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
openstack network create my_network \
|
||||
--provider-network-type vlan \
|
||||
--provider-physical-network physnet1 \
|
||||
--provider-segment 123 \
|
||||
--mtu 1500 \
|
||||
--external \
|
||||
--default
|
||||
|
||||
Then, configure your provider networks through either Neutron BGPVPN API or
|
||||
with ovn commandline:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
ovn-nbctl set logical-switch < UUID > external_ids:"neutron_bgpvpn\:type"="l3"
|
||||
ovn-nbctl set logical-switch < UUID > external_ids:"neutron_bgpvpn\:vni"="1001" # or any other number
|
||||
|
||||
Now use this network to attach routers on it (so update router:external on
|
||||
the provider network) or share your network among tenants (shared = True)
|
||||
|
||||
And create some routers, or add some instances on the provider network, so a
|
||||
host will start exposing the networks and/or ips.
|
||||
|
||||
Current known limitations
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
- Only one Flat provider network can be exposed per vni. Recommendation is
|
||||
to use VLAN provider networks.
|
||||
|
||||
- Do not use the same VLAN id twice in the same VNI. A provider network with
|
||||
type flat is considered vlan 0.
|
||||
|
||||
- It is not possible to have a tenant network (which is routed through a
|
||||
gateway) in separate VRF's, make sure to use address scopes and subnet pools
|
||||
to prevent ip overlaps, if you are planning to expose tenant networks.
|
||||
|
||||
- Provider networks of type ``flat`` is supported, but is limited (because of
|
||||
how ``flat`` networks operate) to one provider network per bridge mapping.
|
||||
It is recommended to use provider networks of type ``vlan``. That way it is
|
||||
also easier to create multiple provider networks, without having to create
|
||||
new bridgemappings for every provider network.
|
||||
|
||||
Every provider network can be assigned a separate VNI, so IP overlap is not
|
||||
an issue between provider networks, as long as separate VNI's are used for
|
||||
those provider networks.
|
||||
|
||||
