oam-bind ingress cfm md ma egress vrrp vrid

Function

The oam-bind ingress cfm md ma egress vrrp vrid command enables CFM to instruct the MGR module to notify VRRP of a fault.

The undo oam-bind ingress cfm md ma egress vrrp vrid command disables CFM from instructing the MGR module to notify VRRP of a fault.

By default, CFM is disabled from instructing the MGR module to notify VRRP of a fault.

Format

oam-bind ingress cfm md md-name ma ma-name egress vrrp vrid vrid interface { interface-name | interface-type interface-number }

undo oam-bind ingress cfm md md-name ma ma-name egress vrrp vrid vrid interface { interface-name | interface-type interface-number }

Parameters

Usage Guidelines

Usage Scenario

To improve network reliability, associate CFM with VRRP. With this association, when CFM or VRRP detects a link fault, it instructs the MGR module to notify the other mechanism of the fault.

The association between CFM and VRRP can be unidirectional or bidirectional.

If the VRRP module detects a link fault, it instructs the CFM module to notify the remote end of the fault.
If the CFM module detects a link fault, it instructs the VRRP module to perform a link switchover.

Prerequisites

CFM and VRRP have been configured.
