Abstract:
In one embodiment, a plurality of links between a network node and another network node are configured as a link bundle. The network node establishes one or more standby bidirectional forwarding detection (BFD) sessions. Each standby BFD session is associated with one or more links of the link bundle. The network node establishes an active BFD session. The active BFD session is associated with one or more links of the link bundle. In response to non-receipt of returned BFD messages for the active BFD session, one or more new active BFD sessions are selected from the one or more standby BFD sessions. In response to non-receipt of returned BFD messages for the one or more new active BFD sessions, it is determined that the link bundle has failed.
