Routing Issue with VRF Configuration on Juniper Routers

  • 1.  Routing Issue with VRF Configuration on Juniper Routers

    Posted 12 days ago

    Hi everyone,

    I'm experiencing issues with route exchange on two Juniper routers set up with a VRF named AVM. Despite proper configuration, the expected routes aren't appearing in the VRF routing tables, particularly for interfaces ae7.268, ae0.509, and ae0.510. Below are the key configurations:

    Issues Noted:

    • The routes expected to be exchanged via BGP are not visible in the VRF routing table.
    • Interfaces ae7.268, ae0.509, and ae0.510 are configured under their respective VRFs but seem to not participate in routing exchange as expected.

    Any help or pointers would be greatly appreciated as I navigate this configuration challenge. Thank you!
