Policy Framework Configuration Guide - Juniper Networks

Junos 10.4 Policy Framework Configuration Guide
policy-options {
community dunedin members [ 56:2379 23:46944 ];
policy-statement from-dunedin {
from community dunedin;
then {
metric 2;
preference 100;
next policy;
}
}
}
The preceding example modifies the metric and preference for routes that contain
members of community dunedin only.
NOTE: You cannot set or add a community in a policy whose members use
regular expressions or a wildcard.
Delete a particular community from a route, leaving remaining communities untouched:
[edit]
policy-options {
community dunedin members 701:555;
policy-statement delete-dunedin {
then {
community delete dunedin;
}
}
}
Remove any community from a route with the AS number of 65534 or 65535:
[edit]
policy-options {
community my-as1-transit members [ 65535:10 65535:11 ];
community my-as2-transit members [ 65534:10 65534:11 ];
community my-wild members [ 65534:* 65535:* ];
policy-statement delete-communities {
from {
community [ my-as1-transit my-as2-transit ];
}
then {
community delete my-wild;
}
}
}
Match the set of community members 5000, 5010, 5020, 5030, and so on up to 5090:
[edit]
policy-options {
community customers members "^1111:50.0$";
policy-statement advertise-customers {
from community customers;
then accept;
