    Posted 25 days ago
    I have a iBGP for evpn sigaling as follows:
    set protocols bgp group dci type internal
    set protocols bgp group dci local-address 192.168.20.2
    set protocols bgp group dci family evpn signaling
    set protocols bgp group dci local-as 65540
    set protocols bgp group dci neighbor 192.168.10.2
    ​

    BGP is established, but I got the following:

    root@vMX3# run show route table EVPN1-MPLS.evpn.0 hidden
    
    EVPN1-MPLS.evpn.0: 4 destinations, 4 routes (3 active, 0 holddown, 1 hidden)
    + = Active Route, - = Last Active, * = Both
    
    3:192.168.10.2:10::101::192.168.10.2/248 IM
                        [BGP/170] 00:34:45, localpref 100, from 192.168.10.2
                          AS path: I, validation-state: unverified
                          Unusable
    

    192.168.10.2 is reachable

    root@vMX3# run ping 192.168.10.2 source 192.168.20.2 count 1
    PING 192.168.10.2 (192.168.10.2): 56 data bytes
    64 bytes from 192.168.10.2: icmp_seq=0 ttl=63 time=70.015 ms
    
    --- 192.168.10.2 ping statistics ---
    1 packets transmitted, 1 packets received, 0% packet loss
    round-trip min/avg/max/stddev = 70.015/70.015/70.015/0.000 ms
    

    Any clue ?

    thanks !!

    Can you please verify inet.3 and if it contains the next-hop for this Type-3/Inclusive Multicast Route? The show route table inet.3 <NH>would do. If it does not, please try adding a static entry on inet.3 for testing purposes, this should solve recursion towards a valid next-hop for this route.

    thanks a lot !!
    After I posted this, I noticed  my routing tables missed inet.3 one, as I did not configure the lookback interface on the P router.
