  • Page 282: Reflector Cluster-Id (Bgp View/Bgp-Vpn Instance View)

    Default level 2: System level Parameters None Description Use the reflect between-clients command to enable route reflection between clients. Use the undo reflect between-clients command to disable this function. By default, route reflection between clients is enabled. After a route reflector is configured, it reflects the routes of a client to other clients. If the clients of a route reflector are fully meshed, you need disable route reflection between clients to reduce routing costs.

  • Page 283: Refresh Bgp

    Typically, a cluster has only one route reflector. The router ID of the route reflector is the ID of the cluster. You can configure multiple route reflectors to improve network stability. Using this command can configure the identical cluster ID for all the route reflectors to avoid routing loops. Related commands: reflect between-clients and peer reflect-client.

    When a BGP router receives an iBGP route, it checks only whether the next hop is reachable by default. If the synchronization is enabled, the iBGP route is synchronized and advertised to eBGP peers only when the route is also advertised by IGP. Otherwise, the iBGP route cannot be advertised to eBGP peers. Examples # Enable the synchronization between BGP and IGP routes.

    By default, no default route is redistributed. Using the import-route command cannot redistribute a default route. To do so, you need to use the default-route-advertise command. If no default route exists in the router's routing table, use the default-route-advertise always command to generate a default route in a Type-5 LSA. You can reference a routing policy to set the cost and type of the default route: The router advertises the default route only when it passes the routing policy.
