BGP & OSPF

Then why you wrote this, at the first palce?

"On one of the vdoms I have some ospf routes - and I want them distributed into my BGP."

If you want to advertise to only limited BGP neighbors, you should set route-maps in BGP neighbor config, and applies them to two groups, 1) neighbors not to advertised, and 2) neighbors to be advertised.

On the other hand, if you have a lot of OSPF routes and you want to redistribute only some of them into BGP, you should construct a prefix-list to match only those you want to redistribute, then use it in a route-map, and use it under the redistribution section. Examples are below:

config router bgp

    set as xxxx1

    set router-id xxx.xxx.xxx.xxx

    config neighbor

        edit "yyy.yyy.yyy.yyy"

            set soft-reconfiguration ena

            set remote-as  xxxx2

            set route-map-out "ADVERTISE-ROUTEMAP"

        next

        edit "zzz.zzz.zzz.zzz"

           set soft-reconfiguration ena

            set remote-as  xxxx2

            set route-map-out "NOT-ADVERTISE-ROUTEMAP"

        next

    config redistribute "ospf"

        set status ena

        set route-map  "REDIST-ROUTEMAP-NAME"

   end
