RIP routing update not showing up

newnetman
Level 1
Level 1

Hello,

From an ABR, i have RIP and OSPF running but unfortunately my "show ip route" could not give either of routes to other paths as required. Not showing up at all. Yet, my debug ip rip and debug ip ospf adj and event reveals no indications for this, even though all concerned IP ADD are up and running.

Any help to resolve this shall be highly appreciated.

Thanks

So i I understand you correctly:

You have an ABR which runs RIP & OSPF. But they are not displayed if you do a "show ip route"?

Could you show us your config for "router rip" & "router ospf"?

as also you show ip route?

I have an idea but I am not sure what yuou mean.

Hello,

Here is the output and i hope it will help to help me further?.

This is the output of sh ip rou on the ABR

This is the output of the Serial neighbor to the ABR, though yet connected to other neighbors. Only its relationship with the ABR could not be seen.

Can you also post results of " show ip ospf neighbor " and "show ip protocol" on ABR.

Router-Peter <---Ethernet-----> Router3-Mark(ASBR) <------ FR -------> Router2-John

are you able to ping the serial interface IP of ASBR from Router2-John

you seem to be using a subinterface there, you might need to recheck your framerelay map configuration there

Hello New,

be aware that connecting a main FR serial interface and a subinterface can cause problems if the subif is point-to-point on one side you have an OSPF network type mismatch that can cause strange problems.

post

Router2-John# sh run int s0/0.1

sh ip ospf int se0/0.1

Router-Peter# sh ip ospf int ser1/0

check for the OSPF network type

Hope to help

Giuseppe

Can you also do a

on ABR:

- show run | section router rip

- show run | section router ospf

on RIP only router:

- show run | section router rip

on OSPF only router:

- show run | section router ospf

if the IOS does not support the command section, it is your ospf and rip config.

This way we can see how you configured things.

Here are requested outputs. Thanks in advance
