currently we're using 2 MLXe-16 routers as upstream routers for some more specific routers and i'm trying to advertise our aggregates and additionally our sub aggregates to our upstream providers, but i collapse with the configuration at the moment.
For for exampe, we have the following aggregate. This aggregate we want to advertise with some specific parameters, eg with as path prepending.
What we try to achieve is, to advertise 10.10.0.0/16 and additionally 10.10.0.0/24,10.10.1.0/24, 10.10.10.2.0/24 and so on.
What we tried is to configure the big aggregate as "aggregate-address". But unfortunately it is not working as exspected.
router bgp aggregate-address 10.10.0.0/16 advertise-map ADVERT-MORE aggregate-address 10.10.0.0/16 attribute-map 3PREPEND route-map ADVERT-MORE permit 5 match ip prefix-list ADVERT-MORE ip prefix-list ADVERT-MORE permit 10.10.0.0/24 ip prefix-list ADVERT-MORE permit 10.10.1.0/24 ip prefix-list ADVERT-MORE permit 10.10.2.0/24 route-map 3PREPEND permit 10 set as-path 1337 1337 1337
Maybe some one have a hint how to solve our problem?
Thank you and best Regards
