Creating and Applying the Route Filter Policy

The policy described in this section is applied to Router A and does the following:

• Denies routes in network 2001:db8:a004::/48
• Sets the community and MED values for routes in network 2001:db8:4000::/44
• Sets the community and MED values for routes that contain AS path 4977

The following is a route filter policy named custFilter:

entry et1 {
if match all {
nlri 2001:db8:a004::/48;
} then {
deny;
}
}
entry et2 {
if match any {
nlri  2001:db8:4000::/44;
as-path 4977;
} then {
med set 100;
community set "2342:6788";
permit;
}
}

Apply the custFilter inbound policy.
