bestroute region-validation allow-invalid(BGP-VPN instance IPv4 address family view)

Usage Scenario

Regional validation is a solution that combines multiple trusted ASs into a region and multiple regions into a regional confederation. By checking whether the routes received from EBGP peers in external regions belong to the local region, regional validation prevents external regions from hijacking routes in the local region. To improve BGP route selection security, you can run the bestroute region-validation command to apply regional validation results of BGP routes to BGP route selection. If the regional validation succeeds, the route is valid and can participate in route selection. If the regional validation fails, the route is invalid and cannot participate in route selection. To allow the routes that fail the regional validation to participate in route selection, configure the allow-invalid parameter. After the parameter is configured, the routes that fail the regional validation are considered valid and can participate in route selection. The priority of the routes is reduced during route selection.
