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
