EVPN/MPLS vlan aware questions

  • 1.  EVPN/MPLS vlan aware questions

    Posted 07-05-2021 00:57
    I have the following topology

    From CE1-192.168.1.1, I can reach CE1-192.168.2.2, but not CE2-192.168.2.3.
    From CE2-192.168.1.2, I can reach CE2-192.168.2.3, but not CE1-192.168.2.2
    On vMX3, I have the following:

    It seems to me vMX3 knows how to send icmp request to vMX4, but it does not.

    root@vQFX-1# run traceroute 192.168.2.3 routing-instance CE1-Red141

    I do not understand the following:

    root@vMX-LS-1# run show arp no-resolve logical-system vMX3   
    MAC Address       Address         Interface         Flags
