9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information
This feature is advertised to BGP neighbors through a capability advertisement. In Receiver Only mode, BGP saves
the advertised routes of peers that support this capability when they restart.
BGP graceful restart is active only when the neighbor becomes established. Otherwise it is disabled. Graceful-
restart applies to all neighbors with established adjacency.
bgp non-deterministic-med
Compare MEDs of paths from different autonomous systems.
Syntax
bgp non-deterministic-med
To return to the default, use the no bgp non-deterministic-med command.
Defaults Disabled (that is, paths/routes for the same destination but from different ASs do not have their MEDs
compared).
