bfd bind peer-ip default-ip

bfd bind peer-ip default-ip

Function

The bfd bind peer-ip default-ip command creates a BFD binding for detecting the physical status of a link.

The undo bfd session-name command deletes a specified BFD session and the created BFD binding.

By default, BFD binding is not created.

Format

bfd session-name bind peer-ip default-ip interface interface-type interface-number [ source-ip ip-address ]

undo bfd session-name

Parameters

Parameter

Description

Value

session-name

Specifies the session name of BFD.

The value is a string of 1 to 15 characters without spaces.

peer-ip default-ip

Indicates the default multicast IP address that is bound to a BFD session.

By default, BFD uses the multicast IP address 224.0.0.184. You can set the multicast IP address by running the default-ip-address command.

interface interface-type interface-number

Specifies the type and number of the interface bound to a BFD session.

  • interface-type specifies the interface type.

  • interface-number specifies the interface number.

-

source-ip ip-address

Indicates the source IP address carried in BFD packets. If the source IP address is not specified, the system searches the local routing table for an outbound interface from which the peer IP address can be reached. The IP address of this outbound interface is used as the source IP address of BFD packets sent by the local end. Generally, this parameter is not required.

Usage Guidelines

Usage Scenario

If source-ip is specified, the URPF-enabled device does not incorrectly discard BFD packets. Ensure that the source IP address is correct. The system only checks whether the source IP address is valid (for example, it cannot be a multicast or broadcast address) without checking correctness.

Precautions

If the IP address of an outbound interface is changed after a BFD session is configured, the source IP address of BFD packets is not updated.

After the bfd bind peer-ip default-ip command is executed, run the commit command to commit the configuration to make the configuration take effect.

Example

# Create a BFD session named test, and then detect the one-hop link that is bound to the local interface GigabitEthernet0/0/1 through the default multicast IP address.
