Abstract:
A method and apparatus for recovering from a controlled failover of a BGP speaker is provided. A user sends, to a network element, a request to switch a designation of an active Border Gateway Protocol (BGP) speaker of the network element from a first BGP speaker to a second BGP speaker. After receiving the request, the network element pauses operation of a transport for BGP. Routing data, which describes a state of a first routing information base (RIB) maintained by the active BGP speaker, is transferred from the first BGP speaker to the second BGP speaker. Thereafter, the first BGP speaker may instruct the second BGP speaker to become the active BGP speaker. After the second BGP speaker becomes the active BGP speaker, the second BGP speaker resumes operation of the BGP transport.
