30 seconds
-
180
seconds
-

shown ip route output shown in the exhibit? (choose two)

The
next routing update can be expected in 35 sedonds
-
The
IP address 10.10.10.6 is configured on S0/1
-
The
IP address 10.10.10.8 is configured on S0/1

13. S0/0 on R1 is configured as a multipoint
interface to communicate with R2 and R3 in the hub-and-spoke Frame Relay
topology shown in the exhibit. Originally, stattic routes were configured
betwwn these routers to successfully route traffic between the attached
networks. What will need to be done in order to use RIPv2 in place of the
static routes?
-
Configure
the no ip subnet-zero command on R1, R2 and R3
-
Dynamic
routing protocols such as RIPv2 cannot be used across Frame Relay networks
-
Configure the S0/0 interface on R1 as two subinterfaces and configure
point-to-point links to R2 and R3
-
Change
the 172.16.2.0/25 and 172.16.2.128/25 subnetworks so that at least two bits are
borrowed from the last octet.

Change
the network address configuration to eliminate the discontiguous 172.16.2.0/25
and 172.16.2.128/25 subnetwork.

-
Routing traffic load is reduced when used in stub network links
-

efficient algorithm is used to build routing tables, using automatic updates.
-

Router#
show ip eigrp interfaces

Router# show ip eigrp
neighbors

two statements are true regarding EIGRP? (Choose two)
-
Passive routes are in the process of being

-
EIGRP supports VLSM,
route summarization, and routing update authentication.

EIGRP exchanges full routing table information
with neighboring routers with every update
-
If the feasible successor has a higher
advertised distance than the successor route, it becomes the primary route
-
A query process is used
to discover a replacement for a failed route if a feasible successor is not
identified from the current routing.
