Dear All,
Today I faced a strange problem and I want to share it with you to find what is the problem ?
we have a VRF for one customer and we use interface vlan to define customer's branch.
The customer interface is VLAN 422 and it is defined under customer VRF probably .
PE#sh running-config vrf V3056:RIYADHBANK
Building configuration...
Current configuration : 1321 bytes
ip vrf V3056:RIYADHBANK
rd 65000:3887
maximum routes 1400 80
route-target export 65000:5405
route-target import 65000:5405
route-target import 65000:5406

we can see the interface vlan is up
PE-L3Agg-Khu-107-2#sh int vlan 422 description

and we can see the vlan 422 belongs to the correct VRF
PE#sh vrf V3056:RIYADHBANK
Name Default RD Protocols Interfaces
V3056:RIYADHBANK 65000:3887 ipv4 Vl627

when we tried to troubleshoot the customer routing we found :
PE-L3Agg-Khu-107-2#ping vrf V3056:RIYADHBANK 172.29.12.97
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.29.12.97, timeout is 2 seconds:

Success rate is 0 percent (0/5)

we could not ping the ip address of interface vlan 422.
PE#sh ip route vrf V3056:RIYADHBANK 172.29.12.97

My question is: Why the interface vlan 422 is not installed in VRF Table as it is UP ??
thanks in advance!
