Continue checking their connected interfaces with the

Continue checking their connected interfaces with the “show running-config” command:
R1#show running-config<<output omitted>>!interface Ethernet0/1description **Connected to L2SW**ip address 10.10.230.1 255.255.255.0ip ospf hello-
interval 25ip ospf 1 area 0!<<output omitted>>
R2#show running-config<<output omitted>>!interface Ethernet0/1description **Connected to L2SW**ip address 10.10.230.2 255.255.255.0ip ospf 2
area 0!<<output omitted>>
We see the hello interval on R1 is not the same as R2 (and you can verify with the “show ip ospf interface <interface> command”) -> There is a hello
and dead interval mismatch problem. We should configure “no ip ospf hello-interval 25″ on R1.
Note: Maybe there are some versions of this question in the exam. For example there are some reports saying that Ethernet0/1 on R1 is shutdown (and
this is the correct choice in the exam). So please be careful checking the config on the routers before choosing the correct answers.
