sh mpls forwarding-table and IPv6

Unanswered Question
Sep 4th, 2007


I am running IPv6 over MPLS (not 6PE) but I cant see the bindings using "sh mpls ldp bindings" nor the forwarding info using "sh mpls forwarding-table", are these commands IPv4 only?

I can try: sh ipv6 cef, which gives me the info but in a different format.

Thanks for your help,


I have this problem too.

I'm not sure I understand what you mean by IPv6 over MPLS if not 6PE. LDP or RSVP for ipv6 are not supported yet.

Could you please explain.

Just to add. Not only LDP and RSVP for ipv6 are not supported but as far as I know they are not standardized either.

Do you mean there is not native IPv6 over MPLS implementations yet?

I can see LDP defined for IPv6 in rfc3036 & 3815...

Sorry my bad. It seems like the RFC does cover IPv6 as well. No vendor that I know of implements it though.
