5.2.4 Checking the Configuration

By viewing the status and type of a BFD session, you can check whether the configurations are
successful.
Prerequisite
The configurations of a single-hop BFD session are complete.
Issue 02 (2011-09-10)
correct source IP address for BFD packets during the creation of a BFD binding;
otherwise, BFD packets are discarded mistakenly.
– On a Layer 2 interface or a Layer 3 physical member interface without an IP address, run:
bfd cfg-name bind peer-ip default-ip interface interface-type interface-
number [ source-ip source-ip ]
session:
bfd cfg-name bind peer-ipv6 peer-ipv6 [ vpn-instance vpn-instance-name ]
interface interface-type interface-number [ source-ipv6 source-ipv6 ]
– If a single-hop BFD6 session is to be created for the first time, the peer IPv6 address and
local outbound interface need to be bound to the session. The bindings cannot be modified
after the BFD6 session is successfully created.
– When creating a BFD6 session, the system checks only the format, not the correctness,
of a peer IPv6 address. An incorrect peer or source IPv6 address leads to a failure in
creating a BFD6 session.
discriminator local discr-value
discriminator remote discr-value
NOTE
l The local discriminator set on a device is equal to the remote discriminator set on a remote device, and
the remote discriminator set on the local device is equal to the local discriminator set on the remote
device. If the discriminators on the device and the remote device do not match, the session cannot be
created. After the local and remote discriminators are set successfully, they cannot be changed.
l In a BFD session to which a default multicast address is bound, its local and remote discriminators
must be different.
NOTE
After necessary parameters, such as local and remote discriminators, are configured for a single-hop BFD
session, the commit command must be run to make the configuration take effect.
