3.4.4 Checking the Configuration

By viewing the type of a BFD session, you can check whether the configurations are successful.
Prerequisite
The configurations of a BFD session with automatically negotiated discriminators are complete.
Procedure
l
----End
Example
# After the configuration is complete, run the display bfd session all verbose command. You
can see that a BFD session of the Static_Auto type has been established. The local and remote
discriminators of this BFD session are 8193 and 8192 respectively and have been obtained based
on automatic negotiation.

NOTE
l The source IP address must be specified.
l The peer IP address must be specified, which cannot be a multicast IP address.
NOTE
A BFD session currently does not detect route switching. If the change of bound peer IP address causes a
route to switch to another link, the BFD session is negotiated again only when the original link fails.
Run the display bfd session { all | static | dynamic | discriminator discr-value | peer-ip
peer-ip [ vpn-instance vpn-instance-name ] } verbose command to check information
about a BFD session.
