MPLS VPNs - from CE cannot ping adjacent ip address of PE when interface in a VRF

[admin_2]

from a CE router (no routing protocols enabled yet) I try to ping the directly attached ethernet on the PE router - there is no response. The config on the PE router is quite simple - an ip address and the interface is in a defined VRF. I do a debug ip packet on the PE router and try to ping out to the attached CE router and I get "unroutable". When I do a "sh ip route" the subnet on the interface (192.168.1.0/30) does not appear in the routing table (ip subnet-zero is enabled). If I do a "sh ip ro vrf <vrf-name>" the subnet appears. If I remove the interface from the VRF and put the ip address back on I can ping ok. Am I missing something? PE IOS is 12.2(6)

Once you put the interface on the PE

in vrf forwarding, it removes the IP address from the global routing table

and hence you cannot ping it. It only expects to receive routing update specific

to the vrf over the vrf interface or IP packet destined for route known

to the vrf nt the global routing table.

Thats how its suppose to work.
