display bier ipv6 routing-table

Function

The display bier ipv6 routing-table command displays information about the BIERv6 routing table.

Format

display bier ipv6 routing-table [ sub-domain id [ bsl { 64 | 128 | 256 } ] ] [ prefix prefix-ipv6 | end-bier end-bier-addr ] [ verbose ]

Parameters

Parameter	Description	Value
sub-domain id	Specifies the ID of a BIERv6 sub-domain.	The value is an integer ranging from 0 to 255.
bsl	Specifies a BSL in BIERv6 encapsulation.	The value can be 64, 128, or 256.
prefix prefix-ipv6	Specifies the IPv6 address of a next hop.	The value is a 32-digit hexadecimal number in the format of X:X::X:X.
end-bier end-bier-addr	Specifies the next-hop End.BIER address.	The value is a 32-digit hexadecimal number in the format of X:X::X:X.
verbose	Displays detailed information about the BIERv6 routing table.	-

Usage Guidelines

Usage Scenario

To view information about the BIRT in multicast over BIERv6 scenarios, run the display bier ipv6 routing-table command. When prefix-based filtering is used, the system filters routes based on the dynamic next hop prefix and displays only dynamic routing information. When End.BIER-based filtering is used, the system filters routes based on the static next hop End.BIER address and displays only static routing information.

Example

The actual command output varies according to the device. The command output here is only an example.
