I currently have a couple sites that connect to an MPLS that uses BGP. I'm trying to figure out how the MPLS provider is getting my routes from Location 1, 2, and 3 to the other locations. Right now all of my locations have this setup for BGP: So the router bgp 65531 is the same at all of my locations. The remote-as is always the same and the only change is the IP for the neighbor.
router bgp 65531
no synchronization
bgp log-neighbor-changes
redistribute connected
redistribute static
neighbor 10.101.0.50 remote-as 13576
neighbor 10.101.0.50 soft-reconfiguration inbound
no auto-summary
So if Location 1 is 192.168.1.0/24 and location 2 is 192.168.2.0/24 and location 3 is 192.168.3.0/24 how are these routes getting into the tables of the other locations. If I add a subinterface to my router at location 1 of 192.168.100.0/24 it will show up in the routing table at location 2 and 3. So on the router that this all connects to how are thing distributing these networks to my other locations? I've got 3 routers in a lab here setup. 1 of them is acting as the MPLS and the other two are connected via serial links to it. So the MPLS currently has:
router bgp 13576
syncronization
bgp log-neighbor-changes
redistribute connected
neighbor 10.101.0.49 remote-as 65531
neighbor 10.101.0.54 remote-as 65531
So the Location 1 and 2 routers have the same output as I llisted up above here. I for some reason figured the routes from location 1 and 2 would exchange but they are not. They do however exchange and show up on the MPLS router..they just don't quite make it to the location routers?
