Which of the following must match for two directly connected routers running OSPF to establish a
neighbor adjacency? (Select 2 choices.)
A.
area IDs
B.
process IDs
C.
router IDs
D.
hello timers

Hello packets are sent every 10 seconds by default. In order for OSPF routers to establish
neighbor adjacencies and exchange routing information successfully, the hello interval needs to

The area number is a number from 0-255, declared at the end of the network command after the
wildcard bits. Routers in the same area will exchange routing information or Link State Updates or
LSUs
