Hi Robclav,

Thanks for your response. My understanding is that rip database will install routes when its received(except posion routes). AD is only compared before installing into FIB if IOS have the same longest match prefix.

Correct me if im wrong...

Hi Kelvin,
In order to see what is going on, try to modify RIP administrative distance from 120 to 80 for instance. Then you will be able to see this route installed at rip database instead of eigrp one.
The question is, which one is the purpose for diferents AD? How this is translated to the route exchange?which routes are installed at rip database?

I hope this help you,
Robclav

Hi Forum,

 

Quick and short question.

 

I have 2 routers with a serial connection. RIP and EIGRP process is enabled
on both routers. No filter-list or any list that will filter routes. 1
loopback has been installed into Router A. RIP and EIGRP has 'network' to
this loopback.

 

router rip

 version 2

 network 1.0.0.0 < this is the loopback

 network 192.168.1.0

 no auto-summary

router eigrp 10

 network 0.0.0.0

 no auto-summary

 

On router B, I can see router A's loopback in EIGRP topology table, but I
do not see it in RIP database..and I missing some concept here because I
don't understand this result.

 

>From B's 'debug ip rip', I can see it is receiving the update but it just
doesn't install in the RIP database.

 

*Mar 1 00:23:18.251: RIP: received v2 update from 192.168.1.1 on Serial1/0

*Mar 1 00:23:18.251: 1.1.1.0/24 via 0.0.0.0 in 1 hops

 

Anyone can feedback?

 

Rdgs,

Kelvin
