Starting to test integration/migration of MPLS/TE+VPLS services into an existing network.

Adding a CCR2004, running 7.12rc4 router to an MPLS cloud of CCR1009 routers running 6.49.10. Conforms to reference design.

OSPF+BGP built on IPv4

New router running 7 is operational, complete with TE extensions when path is statically (loosely) defined - In both directions (From V6 endpoint -> V7 endpoint and V7 endpoint -> V6 endpoint).

CSPF works from V6 endpoint -> V7 endpoint.

CSPF does not seem to work from V7 endpoint -> V6 endpoint.

Can anyone confirm this working? If so, any recommendations on troubleshooting?

Share config example on both sides.
