Hi guys. SP--eBGP---routerA--iBGP---L3switch----ospf----routerB----l3mpls---SP2
SP -service provider. In this diagram can i advertise public ip of my routerA to routerB via internal LAN ? Is there are any hidden difficulties at this case?
You should not need to advertise your public IP segment locally to your internal routers. Your public IP should be advertised from router-a to SP and from router-b to SP2.
