I have an MX100 set up as a VPN concentrator/hub for our Meraki networks. It is configured with a warm spare. We are then advertising OSPF to a Cisco layer 3 switch so the local network can see all the spoke networks.
Primary MX100 static IP of 192.168.0.10
Spare MX100 static IP of 192.168.11
Gateway for both 192.168.0.1
Virtual IP of 192.168.0.2
OSPF Router ID is 192.168.0.10
All of this was set up before I arrived.
My question is if the primary MX fails. Will OSPF still be advertised correctly? To me since it is using the static IP for primary MX as the router ID rather than the virtual IP it would fail. Is that correct?
