Configuring RIP (Empty RIP Database)

[Cisco Enthusiast]

Hello everyone, while configuring RIP in VRF, I encountered a problem where RIP is configured, but it's not showing in the database (completely empty).

Here's my configuration:

router rip

version 2

network 192.168.1.0

!

address-family ipv4 vrf red

redistribute connected

network 192.168.1.0

neighbor 192.168.1.12

no auto-summary

exit-address-family

!

address-family ipv4 vrf blue

redistribute connected

network 192.168.1.0

neighbor 192.168.1.13

no auto-summary

exit-address-family

!

Any help would be much appreciated.

I need to see all config

Hello @Cisco Enthusiast,

The "neighbor" statements under the address families are incorrect. The neighbors specified should be the IP addresses of the routers to which the RIP updates should be sent. It seems that you have used the interface IP addresses instead of the neighboring router IP addresses.

You want hairpinning config ?

it seems to be that! Then use the "redistribute rip" command within each VRF's address family configuration. It will redistribute RIP routes into each VRF, allowing the hairpinning of RIP updates between the VRFs. Make sure that you have configured the appropriate VRF routing instances and interfaces for proper communication between the VRFs.

myrouter(config-router-af)#redistribute rip
redistribution of "rip" via "rip" not allowed

[MHM Cisco World]

your config is correct you redistribute connected (loopback) which config with vrf aware 
so 
try the following 
show ip rip vrf RED/BLUE database 

[Cisco Enthusiast]

myrouter#show ip rip vrf blue database
                                 ^
% Invalid input detected at '^' marker.

Hi

 If you run show ip route vrf XX rip ?

[Cisco Enthusiast]

When i type : show ip route vrf xx rip 

the route is there but when i type :show ip rip database 

it's empty ,it's like there is no configuration .

[Flavio Miranda]

And   you have more then one Router and they have similar configuration? Can I see the second router config ?

[Cisco Enthusiast]

Actually it's one router and two vrfs as shown above in full configuration.

[Flavio Miranda]

Right.

 How are you using the command  show ip rip vrf <XX> ?

[Cisco Enthusiast]

it's not :show ip rip vrf xx

but:

show ip router vrf blue rip

show ip route vrf red rip
