bgp bestpath med missing-as-worst
Configures a missing MED value of a path as having the worst MED value.
Syntax: [no] bgp bestpath med missing-as-worst
Description: Multi-Exit-Discriminator (MED) is considered when selecting the best path among many paths. Paths with lower MED are preferred. By default, if a MED is missing, its value is set to 0, or most preferred. All routers in an AS should be configured the same way to ensure a consistent decision process throughout the AS.
Use the bgp bestpath med missing-as-worst command to consider a missing MED value of a path as having the worst MED value, i.e. 4294967294.
Use the no bgp bestpath med missing-as-worst command to reset the value of a missing MED value to the default value of 0.
NOTE Setting MED behavior using the bgp bestpath med missing-as-worst command takes affect immediately for all new routing decisions. To ensure that it affects all routes, use the clear ip bgp * command to reset all routes.
Factory Default: Disabled.
Command Mode: Router Configuration
Example: The following example configures a BGP speaker to consider a missing MED attribute in a path as having the worst value:
router(config)#router bgp 101
router(config-router)#bgp best path med missing-as-worst
router(config-router)#end
router#
