Default

Command Mode
Router Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
This command is used to enable the checking of next hop of the BGP aggregated routes. Only the routes
with the same next hop attribute can be aggregated if the BGP aggregate next hop check is enabled.
Using the no form of this command is to disable the BGP aggregate-next-hop-check.
Example
This example shows how to configure the BGP aggregate-next-hop-check state.
Switch# configure terminal
Switch(config)# router bgp 100
Switch(config-router)# bgp aggregate-next-hop-check
11-5 bgp always-compare-med
This command is used to configure the Multi Exit Discriminator (MED) in best path selection for paths that
are advertised from neighbors in either the same or different autonomous systems. Use the no command
to use MED only for paths that are advertised from neighbors in the same autonomous system.
bgp always-compare-med
no bgp always-compare-med
Parameters
None.
Default
By default, this option is disabled.
Command Mode
Router Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
MED is an attribute that is exchanged between of eBGP neighbors. MED is an attribute specified by a
local peer, and advertised to the remote peer to affect the best path selection result in the remote peer.
The remote peer will not pass the MED value with routes for further path advertisement. The lower MED
value is preferred than the larger MED value.
By default, the MED attribute only affects the selection of paths that are advertised by the same AS. To
use MED to further affects the selection of routes advertised from different AS, enable the always-
compare-med command setting.
