Usage Guidelines

Usage Scenario

After the redirect ip recursive-lookup tunnel command is run, the received routes that carry a redirection extended community attribute preferentially recurse to tunnel. If the tunnel is reachable, they are used for forwarding; if the tunnel is unreachable, these received routes recurse to other routes.

Prerequisites

The BGP FlowSpec peer has been enabled to advertise routes that carry a redirection extended community attribute.

Precautions

In VS mode, this command is supported only by the admin VS.

The SRv6 TE Policy or SRv6 TE Policy Group of tunnel is not supported in a tunnel selector specified in the command.

Example

# Enable a device to preferentially recurse the received routes that carry a redirection extended community attribute to tunnels.
