[j-nsp] BGP route origination with communities

[Harry Reynolds]

Just jumping in here. At first take I think you need to explicitly accept
that static route somewhere. It seems that you want to set the coms, and
then strip them out via the bgp-policies-PEER1-export policy. If so I do not
see where a static route is accepted anywhere. The default BGP policy does
not send a static. I suggest:


>     policy-statement bgp-policies-PEER1-export {
>         term term-1 {
>             from policy ( ! rm-PEER1OUT );
>             then reject;
>         }
>         /* IOS defaults to NOT sending communities, unlike JUNOS */
>         term strip-communities {
>             then {
>                 community delete all;
>                 next term;
>             }
>         }
>         term next-hop-self {
>             then {
>                 next-hop self;
>                 next term;
>             }
>         }
 term new-term { <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
		from {
>                 route-filter 192.168.224.0/19 exact;

>             then {
>                 accept;
>             }
>         }

>         term explicit-default-action {
>             then next policy;
>         }
>     }
