BFD packets. In this case, you need to specify the correct source IP address of BFD packets
by setting the source-ip parameter when creating a BFD session to prevent BFD packets
from being discarded incorrectly.
discriminator local discr-value
The local discriminator is set.
discriminator remote discr-value
The remote discriminator is set.
NOTE
When you set the discriminators, ensure that the local discriminator at the local end is the same as the
remote discriminator at the peer end; otherwise, the BFD session fails to be set up.
NOTE
After setting necessary parameters, for example, local and remote discriminators, during the creation of a
single-hop BFD session, you must run the commit command to make the configuration take effect.
