Refer to the exhibit.
The branch routers have E1 lines into the Frame Relay Service provider network. The exhibit shows just one branch, but the network actually has 30 branches. The HP 6600 Series routers, which are the area border routers (ABRs), have E2 lines into the Frame Relay network.
The routers in the exhibit Open Shortest Path First (OSPF). The enable OSPF on network follows:
In area 2, OSPF is enabled on network 10.2.0.0/16
In area 0, OSPF is enabled on network 10.0.0.0/16
The customer requires resilience at the WAN core. Which design change best supports that requirement?
- A: Add additional links from the HP 6600 Series routers to the WAN
- B: On each branch router, add a floating static route to one of the ABRs in case the OSPF solution fails
- C: Add a Gigabit link between the HP 6600 Series router with a network in area 0 and area 2.
- D: At each branch, add a redundant link between the switch and the router
