What can be done to fix the problem?
RouterA#debug ip ospf events
OSPF events debugging is on
RouterA#
04:43:16: OSPF. Rcv pkt from 10.3.0.2, Ethernet0/1, area 0.0.0.1 mismatch area 0.0.0.2 in the
header
04:43:19: OSPF. Rcv hello from 10.100.100.3 area 0 from Ethernet0/0 10.1.0.1
04:43:19: OSPF. End of hello processing
A.
Change router B E0/1 interface to area 0.
B.
Change router A interface E0/1 to area 0.0.0.2.
C.
Configure the E0/1 interfaces of router A and router B to be in area 0.
D.
Shut down the E0/1 interfaces in router A and router B as OSPF does not allow “back doors”
between areas.
E.
Remove the E0/1 interfaces in router A and router B from the OSPF process. Use static routes
to route data directly from router A to router B to avoid passing data through router C in area 0.
