Usage Guidelines

Usage Scenario

The peer label-route-capability command is applicable to the scenario where labeled IPv4 routes need to be exchanged between the local end and the specified peer.

Configuring the check-tunnel-reachable parameter can only be used to check tunnels on IPv4 public networks.

Prerequisites

The peer as-number command has been run to create a peer.

Configuration Impact

If the peer label-route-capability command is run multiple times, the latest configuration overwrites the previous one.

Precautions

When the capability of sending labeled routes is enabled or disabled, BGP connection is automatically closed and the capability of the neighbor is re-negotiated, and then the BGP connection is automatically established.

Example

# Enable BGP to send the labeled routes.
