Hello Mandragor.

 

Try to configure it with "in/out" parameter.

You can also try with neighbor field instead.

Thank you for your suggestion, but my issue is not to filter which connected networks to announce but on which device - I want to ensure that the connected networks are only announced on the active device, and by using neighbor route-map or prefix-list I still announce any matched network on the standby device as well, unfortunately.

    Hello Mandragor.

    Your syntax should be fine.

    redistribute [connected|isis|kernel|ospf|rip|static] route-map WORD

    The issue could be in how your "conditionalRoutemap" is configured.

    Could you share it?

    Regards,

    Dario.

    Hello Mandragor.

     

    I was checking some production environment with BGP on it and it hasn't got any specific configuration for active and standby units. Actually, I would bet that BGP is not advertising any route in standby unit by default.

     

    Have you validated this somehow? (traffic-capture, show ip route at PE,...)

     

    Regards,

    Dario.
