Zorluk: KolayOSPFv2 Neighbor Adjacencies and Router ID

When establishing an OSPFv2 neighbor relationship between two directly connected router interfaces, certain interface parameters must be identical. Which two parameters must match for a neighbor adjacency to form successfully? (Select two.)

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

Cevap

The OSPF Area ID and the Hello and Dead timer intervals must match between directly connected router interfaces to form an OSPFv2 neighbor adjacency.
For two Cisco routers to successfully form an OSPFv2 neighbor adjacency, specific fields exchanged in Hello packets must match. Both connected interfaces must be configured within the same OSPF Area ID and must share identical Hello and Dead timer intervals.

Adım Adım Çözüm

1
Identify OSPFv2 Hello packet requirements for neighbor adjacency formation.
OSPF Hello packets verify essential parameters prior to forming a neighbor relationship.
Mismatched core parameters in Hello packets cause neighbor discovery to fail.
2
Analyze each candidate parameter against OSPFv2 neighbor requirements.
Area ID and Hello/Dead timers must match. Process ID is locally significant, and Router IDs must be unique rather than matching.
Process IDs do not traverse Hello packets, and duplicate Router IDs conflict within the LSDB.
