  • 1.  MVPN via ldp only

    I have a following topology to test this

    mreceiver <------- PE1  <-------- RR <-------- PE2 <--------- msender

    I used to use rsvp, but I like to test ldp only. I have the following configuration

    set version 14.1R1.10
    set system host-name PE1
    set system services ssh root-login allow
    set chassis fpc 0 pic 0 tunnel-services bandwidth 1g

    set routing-instances spclab protocols pim interface all
    set routing-instances spclab protocols mvpn
    

    On PE2

    root@PE2# run show multicast route instance spclab    
    Instance: spclab Family: INET

    Group: 239.255.0.0
        Source: 10.144.32.12/32
        Upstream interface: ge-0/0/1.1000

    Instance: spclab Family: INET6

    No downstream interface list

    Can I use ldp only for mvpn ? 

    If I use rsvp and configure provider-tunnel rsvp-te, it works.

    thanks for help !!

    Figured out.
    missed  on RR

    set protocols ldp p2mp
