300-410 Exam - Question 254

Question

Refer to the exhibit. A network engineer must establish communication between three different customer sites with these requirements:

* Site-A: must be restricted to access to any users at Site-B or Site-C.

* Site-B and Site-C: must be able to communicate between sites and share routes using OSPF.

PE interface configuration:

interface FastEthernet0/0

ip vrf forwarding Site-A

!

interface FastEthernet0/1

ip vrf forwarding SharedSites

!

interface FastEthernet0/2

ip vrf forwarding SharedSites

Which configuration meets the requirements?

Examice · Accepted Answer

To establish the required communication restrictions and allow inter-site communication and route sharing for Site-B and Site-C using OSPF, the configuration needs different OSPF process IDs for each VRF. Site-A must have its OSPF configurations isolated, while SharedSites, which includes Site-B and Site-C, must share the same OSPF area to enable route sharing. Therefore, configuring different OSPF process IDs for each VRF and ensuring that both VRFs use area 0 meets the requirements. This configuration ensures Site-A remains restricted while allowing full communication between Site-B and Site-C.

I would choose Answer D as it's in only area 0

B also correct as the traffic can flow between areas. Anythoughts ?

diskman · Answer

The OSPF area must be 0 for the both OSPF VRF instances and the OSPF process ID must be different for each respectively
