Refer to the exhibit. The design is being proposed for use within the network. The CE devices are
61
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
• B.via CE B
• C.no WAN routes will be accessible
• D.via CE A and CE B
