3.10. BGP Peer
Definition: A BGP peer is another BGP instance to which the DUT is in the Established state. (See RFC 1771.)
Discussion: In the test scenarios for the methodology discussion that will follow this document, peers send BGP advertisements to the DUT and receive DUT-originated advertisements. We recommend that the peering relation be established before tests begin. It might also be interesting to measure the time required to reach the established state. This is a protocol-specific definition, not to be confused with another frequent usage, which refers to the business/economic definition for the exchange of routes without financial compensation. It is worth noting that a BGP peer, by this definition, is associated with a BGP peering session, and there may be more than one such active session on a router or on a tester. The peering sessions referred to here may exist between various classes of BGP routers (see Section 4.2).
