5000 Series Layer 2/3 Managed Data Center Switch CLI Reference Guide 11-10 bgp aggregate-different-meds Use the bgp aggregate-different-meds command in BGP Router Configuration mode to allow the aggregation of routes with different MED attributes. By default, BGP only aggregates routes that have the same MED value, as prescribed by RFC 4271. When this command is given, the path for an active aggregate address is advertised without a MED attribute. When this command is not given, if multiple routes match an aggregate address, but have different MEDs, the aggregate takes the MED of the first matching route. Any other matching prefix with the same MED is included in the aggregate. Matching prefixes with different MEDs are not considered to be part of the aggregate and continue to be advertised as individual routes. Use the no command in BGP Router Configuration mode to return the command to the default. bgp aggregate-different-meds no bgp aggregate-different-meds Parameters None. Default The default is a matching MED val for all routes aggregated by a given aggregate address. Command Mode • BGP Router Config • IPv6 Address Family Config • IPv4 VRF Address Family Config 11-11 bgp always-compare-med To compare MED values during the decision process in paths received from different ASs, use the bgp always-compare-med command. The MED is a 32-bit integer, commonly set by an external peer to indicate the internal distance to a destination. The decision process compares MED values to prefer paths that have a shorter internal distance. Since different ASs may use different internal distance metrics or have different policies for setting the MED, the decision process normally does not compare MED values in paths received from peers in different autonomous systems. This command allows you to force BGP to compare MEDs, regardless of whether paths are received from a common AS. Use the no command to revert to the default behavior, only comparing MED values from paths received from neighbors in the same AS. bgp always-compare-med no bgp always-compare-med 1030
