Need assistance with label-unicast

  • 1.  Need assistance with label-unicast

    I have two Router reflectors in two different AS for inter-Provider option C. When I came across two different ways to configure label-unicast  in RRs.

    I tested the following:

    On RR1 in AS1

    set protocols bgp group iBGP family inet labeled-unicast resolve-vpn      <<--- remote RR2 loopback in both inet.0 and inet.3

    On RR2 in AS2

    set protocols bgp group iBGP family inet unicast

    set protocols bgp group iBGP family inet labeled-unicast rib-group RR1-loopback

    set protocols bgp group iBGP family inet labeled-unicast rib inet.3

    set routing-options rib-groups RR1-loopback import-rib inet.3

    set routing-options rib-groups RR1-loopback import-rib inet.0

    set routing-options rib-groups RR1-loopback import-policy RR1-loopback

    set policy-options policy-statement RR1-loopback term 1 from route-filter 11.11.11.11/32 exact

    set policy-options policy-statement RR1-loopback term 1 then accept

    set policy-options policy-statement RR1-loopback term 2 then reject   


    Also Remote RR1 in AS1 loopback in both inet.0 and inet.3


    The L2 and L3 vpn works fine.  I like to know whether any difference when I select which one to use.

    thanks !!
