Usage guidelines

Enabling LDP for VPNs is used for the Carrier's Carrier network that uses LDP between the Level 1 carrier

and Level 2 carrier PEs. In such a network, you must enable LDP for each VPN on each Level 1 carrier PE.

The VPN instance specified by this command must have been created by the ip vpn-instance command

in system view.

The GR commands are available only in LDP view. All other commands available in LDP view are

available in LDP-VPN instance view.

Commands executed in LDP view take effect only for the public network. Commands executed in

LDP-VPN instance view take effect only for the specified VPN instance. The GR commands are global

commands and take effect for all VPN instances and the public network.

# Enable LDP for the VPN instance vpn1, and enter LDP-VPN instance view.
