4.11 Redistribution backup
I would love to see a working solution to this distribution problem. So far, I haven't see one.
Here's the issue: When the backup link (132.1.45/0) between R4 and R5 is down, R2 and R3 get R5's routes via EIGRP. That's the solution that most everyone solves. But activate the backup link (shut R5 S0/0). Now R2 and R3 have to get R5's routes via OSPF. Try pinging 18.104.22.168 from R2 or R3 and you'll see what I mean.
Anybody have a working solution?
