    Hello All

    We have a  VDX6740 switches. There is a BGP EVPN session with third-party switches. Everything works fine, but there is a problem with some routes.
    Why are routes with a sticky MAC not installed in FIB?


    This route is installed in FIB:

    Prefix: MAC:[3000030][00c0.b75a.0cb1], Status: BE, Age: 0h57m18s
    NEXT_HOP: 10.32.0.23, Learned from Peer: 10.32.1.1 (65020)
    LOCAL_PREF: 100, MED: none, ORIGIN: igp, Weight: 0
    AS_PATH: 65002
    Extended Community: RT 65000:3000030 RT 65002:1 ExtCom:03:0c:00:00:00:00:00:08 ExtCom:06:00:00:00:00:00:00:01
    Mac Mobility Ext Community: 1
    Extended Community: ExtCom: Tunnel Encapsulation (Type Vxlan)
    L2_vni: 3000030
    ESI : 00.000000000000000000
    RD: 10.32.0.20:1

    # show mac-address-table address 00c0.b75a.0cb1
    VlanId Mac-address Type State Ports
    30 00c0.b75a.0cb1 EVPN Active Tu 61443


    And this one is not:

    Prefix: MAC:[3000030][001c.73d1.f301], Status: E, Age: 0h45m39s
    NEXT_HOP: 10.32.0.21, Learned from Peer: 10.32.1.1 (65020)
    LOCAL_PREF: 100, MED: none, ORIGIN: igp, Weight: 0
    AS_PATH: 65002
    Extended Community: RT 65000:3000030 RT 65002:1 ExtCom:03:0c:00:00:00:00:00:08 ExtCom:06:00:01:00:00:00:00:00
    Mac Mobility Sticky: True
    Extended Community: ExtCom: Tunnel Encapsulation (Type Vxlan)
    L2_vni: 3000030
    ESI : 00.000000000000000000
    RD: 10.32.0.20:1

    # show mac-address-table address 001c.73d1.f301
    Total MAC addresses : 0

    Hello, thank you for providing those details. I ran this past some of our engineers and they requested that you open a support case for this question so we can dig in to this a little further with you. If you can go to the Portal and open a case, they can take it from there.
