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
Enhanced Interior Gateway Routing Protocol (also known as EIGRP) is a proprietary routing protocol developed by Cisco.
It is the fastest Routing protocol out there and even faster than OSPF.
It is an advanced distance vector routing protocol that contains optimisations that are intended to minimise any routing instability that was incurred after topology changes, as well as the bandwidth usage and processing power within the router.
Also keep in mind that the administrative distance of EIGRP is 90 and Ospf is 110 (lower is better)
Here what you need to know about administrative distance for the CCNA objectives :
Directly Connected interface 0
Static route 1
Internal EIGRP 90
OSPF 110
RIP & RIP V2 120
