A router has learned three possible routes that could be used to reach a destination network. One
route is from EIGRP and has a composite metric of 20514560. Another route is from OSPF with a
metric of 782. The last is from RIPv2 and has a metric of 4. Which route or routes will the router
install in the routing table?
A.
the OSPF route
B.
the EIGRP route
C.
the RIPv2 route
D.
all three routes
E.
the OSPF and RIPv2 routes
When one route is advertised by more than one routing protocol, the router will choose to use the routing protocol which has lowest Administrative Distance. The Administrative Distances of popular routing protocols are: EIGRP 90; OSPF 110; RIP 120.
However, still not 100% sure if it actually uses administrative and not composite metric (if so, answer would be RIPv2)
(Enhanced Interior Gateway Routing Protocol) is a network protocol that lets routers exchange information more efficiently than with earlier network protocols.
