Question
The core of a network has four routers connected in a square design with Gigabit Ethernet links using /30 subnets. The network is used to carry voice traffic and other applications. Convergence time is taking more than expected. Which three actions would you take to improve OSPF convergence time? (Choose three.)
Options
- AIncrease MTU of the interfaces to accommodate larger OSPF packets
- BChange the network type to point-to-point on those links.
- CReduce SPF initial timer.
- DIncrease hello interval to avoid adjacency flapping.
- EEnable OSPF.

Explanation
The OSPF SPF Throttling is configured using the command timers throttle spf OSPF router configuration command. spf-start: Initial delay to schedule an SPF calculation after a topology change. Range is 1 to 600000 milliseconds. spf-hold: Minimum hold-time between two SPF calculations. Range is 1 to 600000 milliseconds. spf-max-wait: Maximum wait between two SPF calculations. Range is 1 to 600000 milliseconds. This command is used to delay the SPF algorithm being executed during network instability. SPF Is very CPU intensive.
