display bgp link-state unicast routing-table

Function

The display bgp link-state unicast routing-table command displays BGP-LS route information.

Format

display bgp link-state unicast routing-table [ peer { ipv4-address | ipv6-address } { received-routes | advertised-routes } ] [ type { node | link | ipv4-prefix | ipv6-prefix | te-policy | srv6-sid } ]

Parameters

Parameter	Description	Value
peer ipv4-address	Specifies the address of the IPv4 peer to be displayed.	The value is in dotted decimal notation.
ipv6-address	Specifies the address of the IPv6 peer to be displayed.	The value is a 32-digit hexadecimal number, in the format of X:X:X:X:X:X:X:X.
received-routes	Displays BGP-LS routes received from the specified peer.	-
advertised-routes	Displays BGP-LS routes advertised to the specified peer.	-
type	Indicates route type information.	-
node	Displays node routes.	-
link	Displays link routes.	-
ipv4-prefix	Displays IPv4 prefix routes.	-
ipv6-prefix	Displays IPv6 prefix routes.	-
te-policy	Displays TE Policy routes.	-
srv6-sid	Displays SRv6-SID routes.	-

Usage Guidelines

Usage Scenario

To check BGP-LS route information, run the display bgp link-state unicast routing-table command. BGP-LS routes carry topology information and are classified into five types of routes that carry node, link, route prefix, TE Policy and SRv6-sid information, respectively. Theses routes collaborate in carrying topology information.

Example

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