5.10.8 Configuring LDP Support for LDP-to-SR Stitching
Configure the export-tunnel-table command using the following CLI syntax to
support LDP-to-SR stitching.
CLI Syntax: config>router# ldp
export-tunnel-table policy-name [ policy-name...(up to
5 max)]
Example: config>router>ldp# export-tunnel-table "export-SR"
config>router>ldp# exit
The following example displays the LDP-to-SR stitching LDP configuration output.
*A:NOK-1 Dut-B>config>router>ldp# info
----------------------------------------------
export-tunnel-table "export-SR"
...
exit
...
----------------------------------------------
*A:NOK-1 Dut-B>config>router>ldp#
5.10.9 Enabling LDP Signaling and Services
When LDP is enabled, targeted sessions can be established to create remote
adjacencies with nodes that are not directly connected. When service destination
points (SDPs) are configured, extended discovery mechanisms enable LDP to send
periodic targeted hello messages to the SDP’s far-end point. The exchange of LDP
hellos triggers session establishment. The SDP’s signaling default enables tldp. The
SDP uses the targeted-session parameters configured in the config>router>ldp>
targeted-session context.
The service>sdp>ldp and router>lsp commands are mutually exclusive; you can
either specify an LSP or enable an LDP. There cannot be two methods of transport
in a single SDP.
Note: The specified policy name must be the same as the policy-statement name defined
when configuring the route policy options for LDP-to-SR stitching. Refer to the
7705 SAR Router Configuration Guide, “Configuring LDP-to-Segment Routing Stitching
Policies”.
