bfr-neighbor

Function

The bfr-neighbor end-bier command configures a static BIFT entry.

The undo bfr-neighbor end-bier command deletes a static BIFT entry.

By default, no static BIFT entry is configured.

Format

bfr-neighbor end-bier ipv6-address bfr-id bfrid-start [ to bfrid-end ]

undo bfr-neighbor end-bier [ ipv6-address [ bfr-id bfrid-start [ to bfrid-end ] ] ]

Parameters

Parameter Description Value
ipv6-address

Specifies the End.BIER address of a BFR neighbor.

The value is a 32-digit hexadecimal number in the format of X:X::X:X.

bfr-id bfrid-start

Specifies the start number of a BFR-ID range.

The value is an integer ranging from 1 to 65535.

to bfrid-end

Specifies the end number of a BFR-ID range.

The value is an integer ranging from 1 to 65535.

Usage Guidelines

Usage Scenario

In a scenario of inter-AS BIERv6 traffic forwarding through static entries, you can run this command to manually specify a BIERv6 neighbor for an upstream node of a node that does not support BIERv6 forwarding to generate a static forwarding entry. The device supports the configuration of the End.BIER SID of the next hop that supports BIERv6 forwarding based on the BFR-ID range of the destination node of a multicast flow.

Prerequisites

The protocol static-bift command has been run.

Precautions

The BFR-ID ranges configured for all neighbors in the same sub-domain cannot overlap.

A maximum of 2000 entries can be configured on the device. A maximum of 256 BFR-IDs can be configured in a BFR-ID range.

Example

# Configure a static BIFT entry in sub-domain 0 to directly forward packets destined for BFR-IDs 1 to 10 to the device with End.BIER 2001:db8:1::1.
