bgp rr

Pre-Alpha. This page describes behavior that may change.

RFC 4456 iBGP route reflector. Reflects routes between client peers and non-client peers, appending ORIGINATOR_ID and CLUSTER_LIST for loop detection.

Category

Policy.

Configuration

The route reflector plugin is auto-enabled when any peer has route-reflector-client set to true. No explicit plugin loading is needed.

bgp {
    peer client1 {
        connection {
            remote { ip 10.0.0.1; }
        }
        session {
            asn { local 65000; remote 65000; }
            route-reflector-client true;
        }
    }
    peer client2 {
        connection {
            remote { ip 10.0.0.2; }
        }
        session {
            asn { local 65000; remote 65000; }
            route-reflector-client true;
            cluster-id 1.2.3.4;
        }
    }
}

Leaf	Type	Default	Description
route-reflector-client	boolean	false	Mark this peer as a route reflector client.
cluster-id	IPv4 address	router-id	Override cluster ID for route reflection (RFC 4456 Section 7).

Routes from clients are reflected to all other clients and non-clients. Routes from non-clients are reflected only to clients. ORIGINATOR_ID is set on reflection; CLUSTER_LIST is prepended. Loop detection drops routes where the local cluster-id appears in CLUSTER_LIST.

CLI

Command	Description
show rr status	Returns JSON with running state.
show rr peers	Returns JSON array of peer addresses, remote AS, and up/down state.

Interactions

• Depends on bgp-adj-rib-in for route replay on reconnect.
• Works alongside bgp-rs for combined reflector + route server deployments.
