Hi All,
We are migrating our existing RIPv2 network to an external WAN setup using EIGRP/BGP. ISP is running BGP and we have configured mutual redistribution - all working perfectly well.
For the legacy network we've redistributed RIP into EIGRP on a 'border/gateway' 3750 and all routes are now known within the EIGRP and thus BGP instances as expected. However, the other way around, redistributing EIGRP into RIP is not going so well. Metrics etc. have all been defined as below and the RIP database shows the route being known however no route appears in the other existing RIP neighbours.
current config on the 'border/gateway' 3750 now running both EIGRP & RIP:
router eigrp 555
redistribute rip
network 10.155.63.0 0.0.0.255
default-metric 1500 100 255 1 1500
router rip
version 2
redistribute eigrp 555
network 10.0.0.0
network 194.101.11.0
network 194.227.202.0
default-metric 1
On the same 3750, I can see a test subnet I've created from another WAN connected location (6.6.6.0/24) being learnt from EIGRP over the WAN and redistributed into the RIP database:
3750#sh ip rip database 6.6.6.0 255.255.255.0
6.6.6.0/24 redistributed
[1] via 10.155.63.248,
This is the route known via EIGRP:
3750#sh ip route 6.6.6.0
Routing entry for 6.6.6.0/24
Known via "eigrp 555", distance 170, metric 3328
Tag 100, type external
Redistributing via rip, eigrp 555
Advertised by rip metric 1
Last update from 10.155.63.248 on Vlan9, 00:34:08 ago
Routing Descriptor Blocks:
* 10.155.63.248, from 10.155.63.248, 00:34:08 ago, via Vlan9
Route metric is 3328, traffic share count is 1
Total delay is 30 microseconds, minimum bandwidth is 1000000 Kbit
Reliability 255/255, minimum MTU 1500 bytes
Loading 255/255, Hops 2
Route tag 100
So, all good I thought until I check the routing table of an existing RIP neighbour:
CORE#sh ip route 6.6.6.0
% Network not in table
Any ideas please??

Hi,
configuration looks ok. Can you please enabled "debug ip rip" on both routers and share the output. Also check "show ip rip database" on the core router.

Thanks for the replies and apologies for the delay in responding, been out of the office for a few days.
I've switched off the auto-summarisation to no avail and have uploaded the debug IP rip output from both routers. In searching through the output I can see no errors at all and no mention of my new subnet either?
Thanks,
Stuart

Hello
Try and disable auto summarisation
Eigrp/rip
no auto-summary
