Problem with route-policy and taging

[Kramerz132]

Hey!

I'm trying to apply the following configuration but are receving the follow error:

!!% Policy [aggregate-routes] uses the 'tag' attribute. There is no 'tag' attribute at the bgp aggregation-dflt attach point.

route-policy aggregate-routes
  set community test
  set community test1
  if tag eq 1000 then
    set community (65000:1,65000:2,65000:3)
  endif
end-policy
!
 

router static
 address-family ipv4 unicast
  10.1.1.0/24 Null0 tag 1000 
  
  router bgp 65000
 address-family ipv4 unicast
  aggregate-address 10.1.1.0/24 route-policy aggregate-routes

Hello.

Please find set/match attributes per attach point in the following document - http://www.cisco.com/c/en/us/td/docs/routers/asr9000/software/asr9k_r4-2/routing/configuration/guide/b_routing_cg42asr9k/b_routing_cg42asr9k_chapter_0110.html#con_1240966

Match tag is not supported for the attach point.

The TAG can be used for table operations that touch the RIB, the agg route operation has no knowledge about the RIB (it only knows the BGP table) hence that tag value can't be used in that facinity.
