display bgp link-state unicast routing-table segment-list

Function

The display bgp link-state unicast routing-table segment-list command displays the SID list of the BGP-LS routes with the specified prefix.

Format

display bgp link-state unicast routing-table [ peer ipv4-address { received-routes | advertised-routes } ] bgp-ls-prefix segment-list

Parameters

Parameter	Description	Value
peer ipv4-address	Specifies the address of the IPv4 peer to be displayed.	The value is in dotted decimal notation.
received-routes	Displays BGP-LS routes received from the specified peer.	-
advertised-routes	Displays BGP-LS routes advertised to the specified peer.	-
bgp-ls-prefix	Specifies a BGP-LS route prefix.	For details about BGP-LS route prefix formats, see "BGP-LS" in Feature Description - IP Routing - BGP. The BGP-LS route prefix format is complex. To facilitate your query, run the display bgp link-state unicast routing-table command to check all BGP-LS routes, and copy the prefix of the route whose information is to be queried when specifying prefix.

Usage Guidelines

Usage Scenario

BGP-LS routes carry topology information and are classified into four types of routes that carry node, link, route prefix, and TE Policy information, respectively. Theses routes collaborate in carrying topology information. For details about BGP-LS route prefix formats, see "BGP-LS" in Feature Description - IP Routing - BGP.

Example

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