What is the issue.

Is it for CSC or Inter-AS scenario.

Inter-AS scenario.

I just want to stitch 2 LSPs togheter as it is possible with another vendor routers.

Thanks

You can do that in Cisco with Ebgp send-label capability on the ASBR-ASBR EBGP session.

If the other vendor is Juniper then you have to run family inet labeled-unicast on the ASBR.

Hello Aditya.

I'm not so sure that this is what I want to achieve.

The LSPs are RSVP signaled TE tunnels. They don't have any connection to MPLS VPNs.

Basicaly I'm looking for a way to stitch the two LSPs togheter, as it is possible in Juniper router with ccc.

Thank you

Unfortunately there is no circuit cross-connect as in Juniper where in you can stitch the lsp's.

But for Inter-AS Rsvp-Te lsp's,Cisco supports via the below mentioned.

Dont know abt Inter-Op bit.

Probably you will have to create mpls-lsp with loose Ero and with "no-cspf" turned on in juniper.

OR

Have both the ASBR's either cisco or juniper.
