[j-nsp] BGP group and peer exports

[Kisito Nguene Ndoum]

Hi Levent,

The two levels of export policies can co-exist.
The peer-specific export policy will be applied to the peer only.
The group export policy is applied to the other peers.

See simple example below :

[edit protocols bgp]
lab at router# show
log-updown;
group TRANSIT {
     type external;
     family inet {
         unicast;
     }
     export send-group;
     peer-as 65123;
     neighbor 1.1.29.2;
     neighbor 1.1.22.2 {
         export send-peer;
     }
}

lab at router> show route advertising-protocol bgp 1.1.22.2 [ peer policy 
applied ]

inet.0: 12 destinations, 12 routes (12 active, 0 holddown, 0 hidden)
   Prefix                  Nexthop              MED     Lclpref    AS path
* 10.3.0.0/24             Self                                    1111 2222

lab at router> show route advertising-protocol bgp 1.1.29.2 [ group policy 
applied ]

inet.0: 12 destinations, 12 routes (12 active, 0 holddown, 0 hidden)
   Prefix                  Nexthop              MED     Lclpref    AS path
* 20.3.0.0/24             Self                                    4444 5555 
1111 I

Hope this helps,
- Kisito
