EIGRP uses a robust metric based on both _______________and ______________, so routers make good choices about the best route to use.
Link bandwidth and link delay
Line status and link-state
Backbone area and intra-are route
Tunnel source and tunnel destination
What term describes what a router knows about each route? At the end of the process when a router learns about a route to a subnet, all the router knows is some measurement of distance (the metric) and the next-hop router and outgoing interface to use for that route (a vector, or direction).
Direction vector
EIGRP distance
Link state
Distance vector
EIGRP is less likely to cause a loop than OSPF.
EIGRP sends update messages without UDP or TCP, but it does use a protocol called _____________. _______________ provides a mechanism to resend any EIGRP messages that are not received by a neighbor.
Frame relay
Rapid spanning tree protocol (RSTP)
Reliable transport protocol (RTP)
RIP
Route poisoning is the practice of …
a route failing due to looping
advertise a failed route with a specific metric value called infinity
blocking a router from receiving pieces of information
none of these
A router learns of a potential neighbor by receiving a Hello. The Hello must be received within 40 sec to be a potential neighbor. Then the router checks the following settings to determine whether the router should be allowed to become a neighbor:
It must pass the authentication process if used
It must use the same configured autonomous system number (which is a configuration setting)
The source IP address used by the neighbor’s Hello must be in the same subnet as the local router’s interface IP address/mask
all of these
f a non successor route’s RD is greater than the FD, the route is a feasible successor route.
__________________ is a DV feature that tells the routing protocol to not advertise some routes in an update sent out an interface: routes that list that interface as the outgoing interface. Those routes that are not advertised on an interface usually include the routes learned in routing updates received on that interface.
Split horizon
Route poisoning
Route summarization
Feasible condition
