Single-Hop Detection In Bfd Echo Packet Mode; Bidirectional Detection In Bfd Control Packet Mode - H3C S5800 Series Configuration Manual

For more information about BFD, see BFD Configuration in the High Availability Configuration Guide.
BFD for RIP provides two link detection modes:
Single-hop detection in BFD echo packet mode for a directly connected neighbor. In this mode, a
BFD session is established only when the neighbor has route information to send.
Bidirectional detection in BFD control packet mode for an indirectly connected neighbor. In this
mode, a BFD session is established only when both ends have routes to send and BFD is enabled
on the receiving interface.

Single-Hop Detection in BFD Echo Packet Mode

Follow these steps to configure BFD for RIP (single-hop detection in BFD echo packet mode):
To do...
Enter system view

Bidirectional Detection in BFD Control Packet Mode

Follow these steps to configure BFD for RIP (bidirectional detection in BFD control packet mode):
To do...
Enter system view
