Lets say I have a Network range 192.168.1.0 /24. I have Two routers the Outside Edge Router#1 which would be 192.168.1.254/30 that connect to another router #2 192.168.1.253 /30. Is it possible to advertise 192.168.1.0 /24 in router #2 to my ISP using BGP. In order for Router #2 to talk to the ISP it needs to pass through router #1.
Multi-hop isnt the problem, its the advertisment. We have two networks, 192.168.1.0/24 and 10.1.1.0/24: Router 1 does not run BGP, Router 2 does. The ISP recieved BGP advertisements from router 2 for 10.1.1.0/24, but not for 192.168.1.0/24. I am wondering if this is because to get to the BGP neighbor at the ISP, Router 2 needs to send the advertisement through an interface in the 192.168.1.0 network.
You need to have a route for 192.168.1.0/24 in your routing table for BGP to advertise this network. Your link between the Router 1 and Router 2 is 192.168.1.252/30. If you want to advertise this network then you need a config like this one.
