Description

Enable LDP routing on the router or switch.

You must include the ldp statement in the configuration to enable LDP on the router or switch.

Default

LDP is disabled on the router.

Options

transport-preference ipv4 | ipv6

Select the preferred transport for TCP connection when both IPv4 and IPv6 are enabled. If transport-preference ipv4 is configured, LDP will attempt to establish the TCP connection using IPv4. If transport-preference ipv6 is configured, LDP will attempt to establish the TCP connection using IPv6.

Default: ipv6
