[j-nsp] Next Gen MVPN and signalling protocol

[samuel.gay at bt.com]

Hi group,

Thanks for all your answers.
 
I have done some tests in my testbed.
I was wrong in my mind.

Effectively multicast traffic use P2MP LSP (RSVP-TE) and unicast traffic use "classic" LSP (LDP).

Regards,
Samuel

Samuel,
p2mp RSVP LSP egress LSR lo0.0 IP@ are not present in inet.0/inet.3 and therefore unicast traffic cannot use NGEN MVPN p2mp LSP.
If you have p2p RSVP LSP and you stll want to use LDP (cannot imagine why but let's assume so) then consider changing next-hops of IPv4 unicast/L3VPN/L2VPN routes together with using "no-install-to"  with "install <prefix/mask>" LSP knobs.
