ROS7 - BGP aggregate summary

Sun Mar 12, 2023 10:08 am

Hi all

Having searched, and found conflicting information, I'm pretty lost at how I do what I need to do:

In ROS6 I have config along the lines of:

/routing bgp aggregate add include-igp=yes inherit-attributes=no instance=default prefix=10.92.25.0/24

Eth1 of the router is configured as 10.92.25.60/26.

When this interface is up, the router will advertise 10.92.25.0/24 to its upstream pairs (on Ether 6 and Ether 8).

In order to aggregate in ROS7 - it looks like I need to add a blackholed route for 10.92.25.0/24 - however this is always advertised, regardless of the state of Ether1.

Others suggested it was required to create an address list, and use this as the Output Network - however this been set to a list, or a list that doesn't exist (the default bgp-networks) makes no difference in my case.

Any ideas?

Cheers
