Description

When you configure multicast-only fast reroute (MoFRR), apply a routing policy that filters for a restricted set of multicast streams to be affected by your MoFRR configuration. You can apply filters that are based on source or group addresses.

For example:

content_copy zoom_out_map
routing-options {
    multicast {
        stream-protection {
            policy mofrr-select;
        }
    }
}
policy-statement mofrr-select {
    term A {
        from {
            source-address-filter 225.1.1.1/32 exact;
        }
        then {
            accept;
        }
    }
    term B {
        from {
            source-address-filter 226.0.0.0/8 orlonger;
        }
        then {
            accept;
        }
    }
    term C {
        from {
            source-address-filter 227.1.1.0/24 orlonger;
            source-address-filter 227.4.1.0/24 orlonger;
            source-address-filter 227.16.1.0/24 orlonger;
        }
        then {
            accept;
        }
    }
    term D {
        from {
            source-address-filter 227.1.1.1/32 exact;
        }
        then {
            reject; #MoFRR disabled
        }
    }
    term E {
        from {
            route-filter 227.1.1.0/24 orlonger;
        }
        then accept;
    }
    ...
}
