Category

Policy.

Configuration

Defined under bgp { policy { } } and referenced by name in peer filter chains:

bgp {
    policy {
        prefix-list allow-default {
            entry 0.0.0.0/0 { action accept; }
            entry 0.0.0.0/0 { ge 8; le 24; action accept; }
            entry 0.0.0.0/0 { ge 25; action reject; }
        }
    }
    filter {
        import [ allow-default ];
    }
}

Entries are evaluated in order; first match wins.
