EIGRP & OSPF Questions 2

February 1st, 2021 in ENCOR 350-401 Go to comments

Question 1


Broadcast and Non-Broadcast networks elect DR/BDR while Point-to-point/multipoint do not elect DR/BDR. Therefore we have to set the two Gi0/0 interfaces to point-to-point or point-to-multipoint network to ensure that a DR/BDR election does not occur.

Question 2

Question 3

Question 4


The “network area 0” command on R2 did not cover the IP address of Fa1/1 interface of R2 so OSPF did not run on this interface. Therefore we have to use the command “network area 0” to turn on OSPF on this interface.

Note: The command “network area 0” can be used too so this answer is also correct but answer C is the best answer here.

The “network area 0” command on R1 will run OSPF on all active interfaces of R1.

Question 5

Question 6


We must reconfigure the IP address after assigning or removing an interface to a VRF. Otherwise that interface does not have an IP address.

Question 7


By default, EIGRP metric is calculated:

metric = bandwidth + delay

While OSPF is calculated by:

OSPF metric = Reference bandwidth / Interface bandwidth in bps

(Or Cisco uses 100Mbps (108) bandwidth as reference bandwidth. With this bandwidth, our equation would be:

Cost = 108/interface bandwidth in bps)
