  • 1.  GRE Tunnel Redundancy

     
    Posted 09-28-2022 06:04
    Hello,
    In Junos, GRE virtual interfaces are tied to line card and if the line card fails tunnel become down.
    Is it possible to setup a redundancy mechanism in case we have two line cards?
    Remote end of the GRE accepts only one GRE tunnel. So we can't create a second tunnel for that purpose.
    Thanks.

    LAG + LACP from two different linecards to your upstream device.

    Lets say we configured GRE tunnel with gr-0/0/0 interface. 
    When the line card on slot 0 becomes down system deletes the gr-0/0/0 interface.
    Could you please describe how LAG+LACP solves that issue?
    Thanks.

    Please disregard, as you mention the GRE interface is tied to the linecard - I was thinking only of path resiliency.
