Imagine I have the following functional configuration below.
Then I am exploring a backup circuit via Satellite in case primary MPLS circuit goes down the hill. I get to the backup circuit via the ip route on the bottom - OK.
Note that 98.65.252.60/30 is my serial connection related network connecting to the MPLS network.
Question:
If my goal is to advertise networks and make sure everything is functional in case MPLS circuit goes down, is it important and necessary to advertise 98.65.252.60/30 via BGP? I am just wondering about that since my neighbor command in BGP is pointing to that one. But I am not totally sure... please advise.
