RSVP-TE tunnel between PE and P router

[sachin30720041]

Hello All,

I am working on the following setup.

CE1---(vrf1)PE5---P6---P7--P8--P9--PE10(vrf1)--CE2

 LDP is running on PE5, P6,P7,P8,P9 and P10. BGP VPNv4 session is up between PE5 and PE10. There is an RSVP-TE tunnel between PE5 and P7. I have configured a static route 'ip route 10.10.10.10 255.255.255.255 tunnel1' so that traffic goes through the tunnel. 10.10.10.10 is the loopback of PE10. Traffic goes from CE1 to P7 but P7 drops the traffic. I am not sure why traffic is getting dropped at P7.Am I missing any configuration?

Hi @sachin30720041 ,

You need to enable LDP over the tunnel interface, so that traffic is labelled end to end.

interface tunnel1

mpls ip
