Zorluk: KolayOSPFv2 Neighbor Adjacencies and Router ID

Which TWO parameters in OSPFv2 Hello packets must match between two neighboring Cisco routers for them to successfully form an OSPF neighbor adjacency? (Select TWO.)

  1. OSPF Area IDCevap
  2. Hello and Dead timer intervalsCevap
  3. C
    OSPF Router ID
  4. D
    OSPF Process ID

Cevap

The OSPF Area ID and the Hello/Dead timer intervals must match between neighboring routers to establish an OSPF adjacency.
For two routers to establish an OSPFv2 neighbor adjacency, key configuration parameters exchanged in Hello packets must match. Specifically, the Area ID and the Hello/Dead timer intervals must be identical on both sides of the link.

Adım Adım Çözüm

1
Identify OSPF neighbor adjacency requirements
Neighboring routers exchange Hello packets containing configuration parameters.
For an OSPF adjacency to reach FULL state, specific fields in the Hello packet must match on both routers.
2
Evaluate the parameters
Area ID and Hello/Dead timer intervals are mandatory matching parameters.
Router IDs must be unique per router, and Process IDs are only locally significant.
