[c-nsp] GRE Tunnel interfaces in MPLS VRF

Dear All,
I am having to configure a GRE tunnel between a
Cisco 2600 and SUP-720 acting as MPLS PE.
GRE
CE (2600) <--------> PE (SUP-720)
The tunnel interface on the SUP-720 is in a VRF and I can connect
to the other interfaces connected locally on the same PE from the CE.
However, I am not being able connect to any other interfaces on the
same VRF which are configured on any other PE routers.
So basically I can only connect to routes which are local to the PE where
the GRE tunnel terminates.
Here is my config:
PE (SUP-720)
!
interface Tunnel1
ip vrf forwarding test
ip address 192.168.1.1 255.255.255.252
ip mtu 1460
keepalive 10 3
tunnel source 219.168.33.6
tunnel destination 211.151.241.108
tunnel mode ipip
end
!
CE (2600)
!
interface Tunnel1
ip address 192.168.1.2 255.255.255.252
ip mtu 1460
keepalive 10 3
tunnel source 211.151.241.108
tunnel destination 219.168.33.6
tunnel mode ipip
end
!
Also I am seeing packets hitting the CE from the PE but not getting back to
the PE.
I am running OSPF over the tunnel and I have all the necessary routes in
place.
Has anyone experienced anything similar ?
Any help or input will be very much appreciated.
Regards,
Zahid
