When creating an LR:
- deploy an Edge asynchronously
- create a L2 switch for connecting LR and Edge
- attach a router port to the L2 switch.
- assign ip address 169.254.2.1/28 and nexthop 169.254.2.3 to LR
When set external gateway:
- configure Edge interface and default gateway
- Add static routes to Edge for all logic networks attached to LR via nexthop 169.254.2.1
- configure SNAT rules for all logic networks attached to LR
When add router interface:
- Add static route/SNAT rule for the network attached to LR
When associate floating IP address:
- configure DNAT rule for the floating ip and the port
Tests being done:
- Verified Edge is deployed asynchronously and LR is attached to the internal created L2 switch
- Manually attach Edge's vNic to the L2 switch and Edge is able to ping 169.254.2.1
- Verified router-delete deletes Edge asynchronously and remove the internal L2 switch
- Verified SNAT/DNAT/static-routes rules are configured on Edge in correct order
- Verified external vnic ip address/netmask and default gateway is configured
