Which three values can be used to tag external EIGRP routes? (Choose three.)
A.
The router ID of the router that redistributed the route
B.
The administrative distance of the external protocol
C.
The protocol ID of the external protocol
D.
The cost to reach the router that redistributed the route
E.
The metric from the external protocol
The router ID of the router from which the external protocol route was learned
E.
The metric from the external protocol
The router ID of the router from which the external protocol route was learned
ADMIN Correct answer is A,C, and “The metric from the external protocol”
EIGRP has the notion of internal and external routes. Internal routes are ones that have been
originated within an EIGRP autonomous system (AS). Therefore, a directly attached network that
is configured to run EIGRP is considered an internal route and is propagated with this information
throughout the EIGRP AS. External routes are ones that have been learned by another routing
protocol or reside in the routing table as static routes. These routes are tagged individually with the
identity of their origination.
External routes are tagged with the following information:

External routes are tagged with the following information:
The router ID of the EIGRP router that redistributed the route.
The AS number where the destination resides.
A configurable administrator tag.
Protocol ID of the external protocol.
The metric from the external protocol.
Bit flags for default routing.
