aggregate-address command

[Matt qomat]

I noticed when I first place aggregate-address 10.34.0.0 255.224.0.0 summary-only and than 10.40.0.0 255.255.255.0 to advertise more specific, that route is not placed. If I take out 10.34.0.0 and put 10.40.0.0 and than put 10.34.0.0 back, I can see both advertised. Looks to me the order matters if second aggregate fells into wider aggregate. Did anyone notice this issue?

Hello Mateusz,

you can use the suppress-map option in the aggregate-address command to get the desired behaviour

see

https://www.cisco.com/en/US/docs/ios/iproute/command/reference/irp_bgp1.html#wp1011467

routes that match the route-map will be suppressed the component routes not matching will be advertised in addition to aggregate

Hope to help

Giuseppe
