Backup Routes, Route selection

[msmoon]

Hi~

Their are two routers which have multiple routint protocol, RIP, EIGRP, IGRP, OSPF, no redistribution each other.

At every router, 'Show ip route' show the table of eigrp's routing table.

At this time, each routing protocol have their own routing table, arn't they?

in other wors, "show ip rip database" can show the whole routing table of RIP advertised from other routers?

When I test this situation, I couldn't see the table of RIP on rip database.

what's the point?

administrative distance value? or behavior of routing protocols?

The output of "Show ip route" will be the router's routing table, not the database for each routing protocol. Since EIGRP has the lowest administrative distance, all of your routes will be shown as being sourced from EIGRP, assuming all protocols run on all interfaces.

"Show ip rip database" shows route summarization performed by RIP v2, not the actual RIP database, as we may expect. I don't know of a way to show RIP's database. You can "debug ip rip", and see all routes received by the RIP process.

There are two routers R1, R2.

Both Router have Rip version 2 and OSPF.

when I debug ip rip on R2, I could see the rip update from R1.

But I couldn't find out the networks on R1 at R2's rip database.

What does it mean?

Is it mean that the R2 knows the networks on R1 from OSPF so R2 don't update r2's Rip database?

when I configure RIP Only, I could find out networks on R1.

At the time I add ospf configuration, In Rip database, networks on R1 changed to possibly down.

And then R1's networks in rip database are disappeared.

What is the point?
