  • 1.  VPLS not working.

    Posted 07-30-2024 05:31
    Using the sandbox Intra-AS BGP-CT in vLabs, I configure VPLS on MX routers.

    I configure the following:

    • IP Addressing
    • OSPF
    • MPLS
    • LDP
    • MP-BGP
    • VPLS (using BGP as a signaling protocol)

    The issue arises when I use VLAN-VPLS encapsulation, preventing me from achieving L3 connectivity between CEs.

    When I use ethernet-vpls can achieve L3 connectivity between CEs.

    The only thing I notice is that I do not observe ARP from the interface going from the PE to the CE using the show arp command.

    Thanks for the help.

    What do you see in the vpls tables?

    show vpls mac-table

    Hi!

    I don't see MAC address in any of the PEs.
