7-9 bgp bestpath compare-routerid
This command is used to compare the router ID for identical eBGP paths. Use the no command to revert to disable this
function.

7-10 bgp bestpath med confed
This command is used to configure a BGP routing process to compare the Multi Exit Discriminator (MED) between
paths learned form confederation peers. To disable MED comparison of paths received from confederation peers, use
the no form of this command.
bgp bestpath med confed
no bgp bestpath med confed
Parameters
Default
Command Mode
DXS-3600 Series 10GbE Layer 2/3 Switch CLI Reference Guide
If enabled, the BGP process will compare the confederation AS path length of the
routes received. The shorter the confederation AS path length, the better the route
is.
You can verify your settings by entering show ip bgp parameters command.
This example shows how to enable the BGP process to compare the AS path that
contains some confederation AS numbers.
None.
BGP receives routes with identical eBGP paths from eBGP peers and selects the
first route received as the best path.
Router Configuration.
Level: 8. (EI Mode Only Command)
When comparing similar routes from peers the BGP router does not consider router
ID of the routes. By default, it selects the first received route. Use this command to
include router ID in the selection process; similar routes are compared and the route
with lowest router ID is selected. The router-id is the highest IP address on the
router, with preference given to loopback addresses. Router ID can be manually set
by using the bgp router-id command.
You can verify your settings by entering show ip bgp parameters command.
This example shows how to configure to compare the router ID for identical eBGP
paths for the autonomous system 65534.
None.
By default, this option is disabled.
