redistributing eigrp route into rip issue

Hi everybody

I am trying to redistribute eigrp prefix 10.0.0.0/8 on R1 into rip.

Please consider the following :

R4----199.199.199.0--RIP---R1-----201.201.201.0--eigrp1

R1 config:

R1 is running rip on s0/0 199.199.199.1

R1 is running  eigrp1 on s0/1

Routing table at R1:

R1#show ip route

R    200.200.200.0/24 [120/1] via 199.199.199.4, 00:00:13, Serial0/0

C    201.201.201.0/24 is directly connected, Serial0/1

D    202.202.202.0/24 [90/2681856] via 201.201.201.3, 00:33:04, Serial0/1

C    199.199.199.0/24 is directly connected, Serial0/0

D    24.0.0.0/8 [90/2297856] via 201.201.201.3, 00:10:09, Serial0/1

D    10.0.0.0/8 [90/2297856] via 201.201.201.3, 00:31:52, Serial0/1

R    12.0.0.0/8 [120/1] via 199.199.199.4, 00:00:13, Serial0/0

R1#

The  design requires  R1 should only advertises 10.0.0.0/8 eigrp route into RIp.

So i configure the following:

router rip

redistribute eigrp 1 metric 1 route-map zee

route-map zee permit 10

match ip address 1350

!

route-map zee deny 20

!

access-list 1350 permit 10.0.0.0 0.255.255.255

Based on the above config, only prefix 10.0.0.0 should be redistributed into rip.  But for some reasons, prefixes 202.202.202.0/24 201.201.201.0/24  are being redistributed into rip as well.

R4 is learning not only prefix 10.0.0.0/8 but also prefixes 202.202.202.0/24  201.201.201.0/24  which it should not have.

Below is the routing table at R4

R4# show ip route

C    200.200.200.0/24 is directly connected, Serial0/1

R    201.201.201.0/24 [120/1] via 199.199.199.1, 00:00:15, Serial0/0

R    202.202.202.0/24 [120/1] via 199.199.199.1, 00:00:15, Serial0/0

C    199.199.199.0/24 is directly connected, Serial0/0

R    10.0.0.0/8 [120/1] via 199.199.199.1, 00:00:15, Serial0/0

C    12.0.0.0/8 is directly connected, Loopback12

R4#

My question is why  R1 is redistributing 202.202.202.0/24 and 201.201.201.201.0/24 into rip?

thanks and have a great weekend.

Re: redistributing eigrp route into rip issue

Sarah,

     It should not be a problem. Your configuration looks good to me.  It might be a timing issue. 

Try this

R4#clear ip route *

    You can remove this statement,"route-map zee deny 20"

    If it still doesn't work, please post configuration.

HTH,

Toshi

It was indeed timing issue. Thanks Toshi

Re: redistributing eigrp route into rip issue

Maybe configure s0/0 on R1 as passive interface for eigrp and clear the ip route as Toshi mentioned.
