DGS-3630 Layer 3 Stackable Managed Switch CLI Reference Guide not pass the MED value with routes for further path advertisement. The lower MED value is preferred than the larger MED value. By default, MED 0 is assigned to a route if missing MED missing. Use the bgp bestpath med missing-as-worst command to configure the BGP router to assign a largest MED value to a route if missing MED. Example This example shows how to configure the BGP process 10000 to assign a largest MED value to a route if missing MED. Switch# configure terminal Switch(config)# router bgp 10000 Switch(config-router)# bgp bestpath med missing-as-worst 12-13 bgp client-to-client reflection (MI and EI Mode Only) This command is used to enable route reflection from a BGP route reflector to clients. Use the no form of this command to disable client-to-client route reflection. bgp client-to-client reflection no bgp client-to-client reflection Parameters None. Default By default, this option is enabled. Command Mode Router Configuration Mode. Command Default Level Level: 12. Usage Guideline In a large scale BGP network, route reflection is a mechanism used to reduce the needs of fully mesh of iBGP sessions. With route reflection, an autonomous system can be partitioned into a number of clusters; each cluster is formed by the route reflector and its client. The connection between clusters is still fully meshed. However, in a cluster, the reflector needs to maintain connections with all clients, but the client does not need to maintain connections with other clients. The route reflector is responsible to reflect routes received from one client to other clients. Use the bgp client-to-client reflection command on the route reflector to enable reflection of routes received from the clients to other clients. If the clients are already fully meshed, then use the no bgp client-to-client reflection command to disable client-to-client reflection because route reflection is not required. Example This example shows how to configure the local router is a route reflector with three neighbors as the clients. The client to client reflection is enabled to enable the route reflection. 171
