Note:

The remote-ip-address must match the BFD local-ip-address configured on the remote system.
For LAG null encapsulation, an interface must be created and the micro-BFD IP addresses must match the interface IP address.

Table: Configuring Micro-BFD for Network LAG Using Dot1q Encapsulation with no Interface shows an example of configuring micro-BFD for network LAG using dot1q encapsulation with no interface.

Note:

The remote-ip-address must match the BFD local-ip-address configured on the remote system.
For LAG dot1q encapsulation with no interface, the micro-BFD IP addresses can be any valid addresses.

Note:

The remote-ip-address must match the BFD local-ip-address configured on the remote system.
For LAG dot1q encapsulation with multiple non-zero VLAN interfaces, the micro-BFD IP addresses can be any valid addresses and the interfaces must have non-zero VLANs.

Table: Configuring Micro-BFD for Network LAG Using Dot1q Encapsulation with a Zero VLAN Interface shows an example of configuring micro-BFD for network LAG using dot1q encapsulation with a zero VLAN interface.

Note:

The remote-ip-address must match the BFD local-ip-address configured on the remote system.
For LAG dot1q encapsulation with a zero VLAN interface, the micro-BFD IP addresses must match the interface addresses of the zero VLAN interface.
