Which two statements about the command distance bgp 90 60 120 are true? (Choose two.)
A.
Implementing the command is a Cisco best practice.
B.
The external distance it sets is preferred over the internal distance.
C.
The internal distance it sets is preferred over the external distance.
D.
The local distance it sets may conflict with the EIGRP administrative distance.
E.
The internal distance it sets may conflict with the EIGRP administrative distance.
F.
The local distance it sets may conflict with the RIP administrative distance.
Explanation:
To allow the use of external, internal, and local administrative distances that could be a better
route than other external, internal, or local routes to a node, use the distance bgp command in
address family or router configuration mode. To return to the default values, use the no form of
this command.

no distance bgp
external-distance
Administrative distance for BGP external routes. External routes are routes for which the best path
is learned from a neighbor external to the autonomous system. Accept table values are from 1 to
255. The default is 20. Routes with a distance of 255 are not installed in the routing table.
internal-distance
Administrative distance for BGP internal routes. Internal routes are those routes that are learned
from another BGP entity within the same autonomous system. Accept table values are from 1 to
255. The default is 200. Routes with a distance of 255 are not installed in the routing table.
local-distance
Administrative distance for BGP local routes. Local routes are those networks listed with a network
router configuration command, often as back doors, for that router or for networks that are being
redistributed from another process. Accept table values are from 1 to 255. The default is 200.
Routes with a distance of 255 are not installed in the routing table.
Defaults
external-distance: 20
internal-distance: 200
local-distance: 200
In this case, the internal distance is 60 and the external is 90, and the local distance is 120 (same
as RIP).
