WAN Edge Router Deployment
Question
A network administrator is tasked to make sure that an OMP peer session is closed after missing three consecutive keepalive messages in 3 minutes. Additionally, route updates must be sent every minute. If a WAN Edge router becomes unavailable, the peer must use last known information to forward packets for 12 hours. Which set of configuration commands accomplishes this task?
Options
- Aomp timers advertisement-interval 60 holdtime 180 graceful-restart-timer 43200
- Bomp timers advertisement-interval 1 holdtime 180 graceful-restart-timer 43200
- Comp timers advertisement-interval 1 holdtime 180 graceful-restart-timer 720
- Domp timers advertisement-interval 60 holdtime 60 graceful-restart-timer 720

OMP timers control route update frequency, session timeout based on missed keepalives, and how long stale routing information is retained during a graceful restart.
Common mistakes.
- B. The
advertisement-intervalis set to 1 second, but the requirement is for route updates every minute (60 seconds). - C. The
