The design is being proposed for use within the network. The CE devices are OSPF graceful restart-capable,
and the core devices are OSPF graceful restart-aware. The WAN advertisements received from BGP are
redistributed into OSPF. A forwarding supervisor failure event takes place on CE A. During this event, how will
the routes learned from the WAN be seen on the core devices?
A. via CE A and CE B
B. via CE A
C. via CE B
D. no WAN routes will be accessible
Answer: C
Explanation:
I think the answer should be A. via CE A and CE B. I’m assuming core devices see WAN routes via CE A and CE B before the failure event. Graceful restart should suppress routing changes until the timers expire.

Answer C should be correct. It say “during this event”. Although CE A will keep forwarding, but other routers won’t learn route for CE A, because it is in process of re-build routing table.
