Regarding LOCAL-AS attribute, I4d like to confirm:

A route with a LOCAL_AS attribute can be advertised to peers in other subautonomous systems within a confederation, but I4m trying and it is not working... the route cannot be advertised to another subautonomous systems..

AS3 (R3)......[ AS10 (subAS5 -R5)----- (subAS5 - R2) ........ (subAS6 - R6)]
|
|
222.222.222.0

In this example, R2 (in the same subAS) has 222.222.222.0. R6 (in another subAS) cannot get the same route:

(R5)
router bgp 5
bgp router-id 5.5.5.5
bgp cluster-id 3368601605
bgp log-neighbor-changes
bgp confederation identifier 10
bgp confederation peers 6
neighbor 2.2.2.2 remote-as 5
neighbor 2.2.2.2 ebgp-multihop 5
neighbor 2.2.2.2 update-source Loopback0
neighbor 2.2.2.2 send-community
neighbor 2.2.2.2 route-map MODCOMMUNITY out
neighbor 3.3.3.3 remote-as 3
neighbor 3.3.3.3 ebgp-multihop 5
neighbor 3.3.3.3 update-source Loopback0

access-list 33 permit 222.222.222.0 0.0.0.255

route-map MODCOMMUNITY permit 10
match ip address 33
set community local-as
