Question

A network architect must redesign a data center network based on OSPFv2. The network must perform fast reconvergence between directly connected switches. Which two actions must be taken to meet the requirements? (Choose two.)

Options

AConfigure all links on AREA 0.
BImplement a virtual link between the switches.
CUse OSPF point-to-point links only.
DSet low OSPF hello and DEAD timers.
EEnable BFD for failure detection.

Explanation

Detecting link and node failures quickly is number one priority for fast convergence. For maximum speed, relying on IGP keepalive times should be avoided whether possible and physical failure detection mechanisms should be used. This implies the use of physical point-to-point links whether possible. BFD (BiDirectional Forwarding Detection) provides sub-second convergence for many protocols and is done in hardware. BFD will also only work on point-to- point links.
