The remote discriminator is set.
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. After
local and remote discriminators are set successfully, they cannot be modified.
NOTE
For the BFD sessions that use the default multicast IP address, the local and remote discriminators must
be different.
Step 4
Run:
commit
The configuration is committed.
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.
