oam-bind ingress vrrp vrid egress cfm md ma

Function

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

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

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

Format

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

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

Parameters

Parameter Description Value
vrid vrid

Specifies the ID of a VRRP group.

The value is an integer ranging from 1 to 255.
interface interface-type interface-number

Specifies the type and number of an interface.

-
md-name

Specifies the name of an MD.

The value is a string of 1 to 43 case-sensitive characters. Question marks (?), hyphens (-) are not supported.
ma-name

Specifies the name of an MA.

The value is a string of 1 to 43 case-sensitive characters. Question marks (?), hyphens (-) are not supported. The total length of MA and MD names must be no greater than 44 characters.

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.

    The following commands are used when CFM is associated with VRRP:
  • oam-bind cfm md ma vrrp vrid
  • oam-bind ingress cfm md ma egress vrrp vrid
  • oam-bind ingress vrrp vrid egress cfm md ma

    Table 1 describes CFM and VRRP association configurations.

Table1 CFM and VRRP association configurations

Scenario Configuration Solution 1 Configuration Solution 2
Bidirectional association between CFM and VRRP Run the oam-bind cfm md ma vrrp vrid command to configure the bidirectional association between CFM and VRRP.If you have run the oam-bind cfm md ma vrrp vrid command, the configuration file contains the following commands:oam-bind ingress vrrp vrid egress cfm md ma.oam-bind ingress cfm md ma egress vrrp vrid. Perform the following operations: Run the oam-bind ingress vrrp vrid egress cfm nd ma command to enable VRRP to instruct the MGR module to notify CFM of a fault. Run the oam-bind ingress cfm md ma egress vrrp vrid command to enable CFM to instruct the MGR module to notify VRRP of a fault.
Unidirectional association between CFM and VRRP Perform either of the following operations: Run the oam-bind ingress vrrp vrid egress cfm nd ma command to enable VRRP to instruct the MGR module to notify CFM of a fault.Run the oam-bind ingress cfm md ma egress vrrp vrid command to enable CFM to instruct the MGR module to notify VRRP of a fault. None

Prerequisites

CFM and VRRP have been configured.
