Targeted session commands

targeted-session

Syntax

targeted-session

Context

config>router>ldp

Platforms

Supported on all 7210 SAS platforms as described in this document.

Description

This command configures targeted LDP sessions. Targeted sessions are LDP sessions between non-directly connected peers. Hello messages are sent directly to the peer platform instead of to all the routers on this subnet multicast address.

The discovery messages for an indirect LDP session are addressed to the specified peer and not to the multicast address.

disable-targeted-session

Syntax

[no] disable-targeted-session

Context

config>router>ldp>targ-session

Platforms

Supported on all 7210 SAS platforms as described in this document.

Description

This command disables support for targeted sessions. Targeted sessions are LDP sessions between non-directly connected peers. The discovery messages for an indirect LDP session are addressed to the specified peer and not to the multicast address.

The no form of this command enables the set up of any targeted sessions.

Default

no disable-targeted-session

peer

Syntax

[no] peer ip-address

Context

config>router>ldp>targeted-session

Platforms

Parameters

ip-address

Specifies the IP address of the LDP peer in dotted-decimal notation.

tunneling

Syntax

[no] tunneling

Context

config>router>ldp>targ-session>peer

Platforms

Supported on all 7210 SAS platforms as described in this document.

Description

This command enables LDP over tunnels.

The no form of this command disables tunneling.

Default

no tunneling

lsp

Syntax

[no] lsp lsp-name

Context

config>router>ldp>targ-session>tunneling

Platforms

Supported on all 7210 SAS platforms as described in this document.

Description

This command configures a specific LSP destined for this peer to be used for tunneling of LDP FEC over RSVP. A maximum of four RSVP LSPs can be explicitly used for tunneling LDP FECs to the T-LDP peer.

It is not necessary to specify any RSVP LSP in this context unless there is a need to restrict the tunneling to selected LSPs. All RSVP LSPs with a to address matching that of the T-LDP peer are eligible by default. The user can also exclude specific LSP names by using the ldp-over-rsvp exclude command in the configure>router>mpls>lsp context.

Default

no tunneling
