display mpls lsp (asbr/protocol bgp)

Function

The display mpls lsp asbr command displays on an ASBR information about LSPs created using BGP based on received VPNv4 or VPNv6 routes (excluding LSPs lacking forwarding tokens).

The display mpls lsp protocol bgp command displays information about LSPs created using BGP based on received IPv4 VPN routes (excluding LSPs lacking forwarding tokens).

The display mpls lsp protocol bgp-ipv6 command displays information about LSPs created using BGP based on received IPv6 VPN routes (excluding LSPs lacking forwarding tokens).

Parameters

Parameter	Description	Value
nexthop nexthop-addr	Specifies the next hop IPv4 address.	This value is in dotted decimal notation. This address can be displayed using the display mpls lsp verbose command.
nexthop6-addr	Specifies the next hop IPv6 address.	The value is a 32-digit hexadecimal number, in the format of X:X:X:X:X:X:X:X.
verbose	Displays detailed information about LSPs.	-
asbr	Displays information about ASBR LSPs.	-
bgp-ipv6	Displays information about LSPs created using BGP based on received IPv6 VPN routes.	-
exclude	Displays information about LSPs that are not mapped to a specified FEC.	-
fec-prefix	Displays information about LSPs of a specified IPv4 address.	This value is in dotted decimal notation. This address can be displayed using the display mpls lsp verbose command.
fec-prefix-length	Specifies the mask length of the specified IPv4 address.	The value is an integer ranging from 0 to 32.
fec6-prefix	Displays information about LSPs of a specified IPv6 address.	The value is a 32-digit hexadecimal number, in the format of X:X:X:X:X:X:X:X.
fec6-prefix-length	Specifies the length of the IPv6 address prefix.	The value is an integer ranging from 0 to 128.
lsr-role	Displays information about an LSP according to the specified role of the local LSR.	-
egress	Displays information about LSPs with the local LSR as the egress.	-
ingress	Displays information about LSPs with the local LSR as the ingress.	-
transit	Displays information about LSPs with the local LSR as a transit node.	-
include	Displays information about LSPs that are mapped to a specified FEC.	-

Usage Guidelines

Usage Scenario

In an inter-AS VPN Option B or Option C scenario, to check information about LSPs created using BGP based on received VPNv4 or VPNv6 routes (excluding LSPs lacking forwarding tokens), run the display mpls lsp asbr command on an ASBR.

In a BGP/MPLS IP VPN or BGP/MPLS IPv6 VPN scenario, to check information about LSPs created using BGP based on received VPN routes (including the incoming/outgoing labels of VPN routes and corresponding VPN instances), run the display mpls lsp protocol bgp command on a PE or ASBR.

Example

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