[c-nsp] Not able to export MPLS egress net flows from PE routers

[Tirumalarao Burre]

Hi Experts,


I need yout help to capture MPLS egress net flows from PE routers.


Here is my MPLS VPN test setup details.

CE1-----PE1-----P1---P2---PE2---CE2


IOS tried:: 12.4(15)T6, 12.4(24)T


PE1 router configuration attached.


I am trying to export MPLS egress net flows from PE1 router(interface
pointing to P1 router) to netflow capturing server.

MPLS VPN topology is UP and I could ping successfully from CE1 to CE2.

When I capture packets on my flow capture destination server, I could not
receive MPLS packets.


Could you guide me how to capture MPLS egress net flows from PE routers
where I could see MPLS labels.
