Hi,
I am having some problem with VRF-LITE using RIP and redistribute connected. VRF-Lite is configured between a Cisco 7204VXR running
c7200p-advipservicesk9-mz.124-24.T4.bin and a Cisco ME 3400 running me340x-metroipaccess-mz.122-35.SE4.bin. The configurations are as following :
ROUTER-A(7200 VXR)

Output of ROUTER B
===============
Routing Table: A

C 172.16.102.0/30 is directly connected, GigabitEthernet1/0.11

B 10.222.25.128/30 [200/1] via B.C.D.E, 5d06h
Output of SWITCH A
==================
Routing Table: A
Gateway of last resort is 172.100.101.1 to network 0.0.0.0
172.100.0.0/16 is variably subnetted, 2 subnets
R 172.16.102.0/30 [120/1] via 172.16.101.1, 00:00:10, Vlan11
C 172.16.101.0/30 is directly connected, Vlan11
10.0.0.0/8 is variably subnetted, 2 subnets
C 10.222.25.136/30 is directly connected, FastEthernet0/3
C 10.222.25.128/30 is directly connected, FastEthernet0/2
Now the problem is although there is an IP address 172.16.3.0/30 connected in ROUTER A and I have configured "redistribute connected" in rip but that route is not advertised to the switch. What am I missing?

Hi,
You could try to disable split-horizont on that interface ;
Router A
interface GigabitEthernet0/0.11
no ip split-horizon
