Re: IGP Mutual Redistribution

If there is no route feedback then there wont be any necessity to tinker with admin distances, however if there are at least two points of mutual redistribution you would have to use one method or another. For example if you are not concerned about suboptimal routing, then the trick with route-map tagging/filtering is the easiest and bullet-proof to implement.

Have practised 4 labs (IE Materials), and have a query for IGP mutual redistribution.

For Example, mutual redistribution between rip and ospf.
R5

router rip

distance 109
I noticed that the answers are always making the RIP distance smaller than OSPF distance (110) even though there is no multiple mutual redistribution between RIP
and OSPF domains. Suboptimal routing is not going to happen since it is ONLY a single point of mutual redistribution. I noticed this is
practised in Lab2 and Lab3, is this some kind of best practice for a "Bigger
Distance Routing Protocol" to be redistributed into a "Smaller
Distance Routing Protocol" even it is just only a single point of mutual
redistribution?

Much appreciated for any kind replies.

Cheers
Nit
