Did you enable "mpls netflow egress" on a non-VRF interface? This
feature is only supported on PE-CE interfaces (i.e. when "ip vrf
forwarding xxx" is also enabled on the interface), so please replace
this with the ingress command "ip route-cache flow" to capture IP
packets.

P.S: I think I was working on a case from one of your collegues about
this very problem..
