Routing Internet Traffic Through Multiple CE Routers: Configuration Summarized by Router

This configuration is an extension of the example in Routing Internet Traffic Through a Hub CE Router. It provides different exit points for various sites by using multiple hub CE routers that perform similar functions.

Routing Instances



routing-instances {


vpna {
instance-type vrf;
interface t3-0/2/0.0;
interface at-1/3/1.0;
route-distinguisher 10.255.14.171:100;
vrf-import vpna-import;
vrf-export vpna-export;


routing-options {


static {
route 0.0.0.0/0 next-hop 10.23.0.1;
}


}




protocols {


bgp {


group to-CE1 {
export export-default;
peer-as 63001;
neighbor 192.168.197.14;
}


}


}


}


}

Policy Options



policy-options {


policy-statement vpna-import {


term a {


from {
protocol bgp;
community vpna-comm;
}


then accept;
}




term b {
then reject;
}


}




policy-statement vpna-export {


term a {


from {
protocol static;
route-filter 0.0.0.0/0 exact;
}




then {
community add public-comm1;
community add vpna-comm;
accept;
}


}




term b {
from protocol bgp;


then {
community add vpna-comm;
accept;
}


}




term c {
then reject;
}


}


community public-comm1 members target:1:111;
community public-comm2 members target:1:112;
community vpna-comm members target:63000:100;
}

The configuration of Router PE2 is identical to that of Router PE1, except that Router PE2 exports the default route through community public-comm2 (see Policy Options).
