Pinging VPLS for connectivity verification

  • 1.  Pinging VPLS for connectivity verification

    Posted 09-16-2019 19:43

    morning,

    I am simply trying to ping CE L3 interfaces from PEs to verify that the vpls instance is up beyond the typical commands. I have found the following command:

     

    ping vpls instance instance-name destination-mac address source-ip address

    Initialization failure: bind to address 10.0.0.3 failed with error "Can't assign requested address"

     

    However I am not able to source from the IP - so it sounds like i need an inet interface in the instance and I am so not see how to do that. I cannot add an inet family to the vpls interface, i can't add a separate inet interface to the routing instance either... so not sure how to progress... any help?

    thanks

    if you want to ping CE L3 interface , then you need l3 interface in on your side, fir example configured via l3-interface ...

    But if you want to check only mpls connectivity between your sites you can ping via

    ping mpls l2vpn instance INSTANCE-NAME remote-site-id 2 local-site-id 1 ..

    Hi,

     

    VPLS being an L2 service, you would not be able to add an L3 interface directly.

    However, you could configure an irb interface to be brought up once the vpls instance comes up.

    https://www.juniper.net/documentation/en_US/junos/topics/task/configuration/vpls-irb-solutions.html

    This irb interface would by default sit in the inet.0 routing-table.

    From this irb interface in inet.0 you could simply ping the CE L3 address:

    ping <ce-ip-address> interface irb.x

    The irb interface can also be moved under a Routing-instance if required:

    set routing-instance <ri-name> interface irb.x

    Hope this helps.

     

    Cheers,

    Ashvin

    Hi!

     

    Normally VPLS is the L2 VPN technology, meaning there is no L3 interface and you could not communite to end CE host directly via L3. But you coudl configure irb under the VPLS routing instance 

     

    Here is the link you could refer:

     

    https://www.juniper.net/documentation/en_US/junos/topics/task/configuration/vpls-irb-solutions.html

     

    If you just want to verify if VPLS connection is up, you could issue below command to check:

     

    show vpls connections
