Session Description
--------------------------------------------------------------------------------
The command output shows that the Echo Passive field indicates Enable, which means that the
passive echo function is enabled for the BFD session. If the Echo Passive field indicates
Disable, this means that the passive echo function is disabled for the BFD session. The passive
echo function can be enabled for a BFD session only when the passive echo function is globally
enabled, the ACL rule (if configured) is matched, and the echo function is enabled on the peer.
5.4 Configuring the Association Between the BFD Status
and the Interface Status
By associating the BFD session status with the interface status, you can trigger fast route
convergence. This function is applicable to only the BFD session that uses the default multicast
IP address to detect the single-hop link.

5.4.1 Establishing the Configuration Task

Before associating the BFD session status with the interface status, familiarize yourself with the
applicable environment, complete the pre-configuration tasks, and obtain the required data. This
can help you complete the configuration task quickly and accurately.
