Demonstrates DR/BDR election on broadcast LAN, ABR between Area 0 and Area 30, ASBR redistributing static into OSPF as Type 5 LSA. Used for ipc-05, ipc-06, ipc-07, ipc-08. notes: |- PingLabz OSPF Reference Lab =========================== TOPOLOGY Area 0 broadcast LAN (10.20.0.0/24) via SW1 R1 (ASBR, Lo0=10.255.0.1) R2 (ABR, Lo0=10.255.0.2, priority 100 to win DR) R3 (internal Area 0, Lo0=10.255.0.3) Area 30 P2P link (10.30.30.0/30) R2 Et0/1 <-> R4 Et0/0 R4 (internal Area 30, Lo0=10.255.0.4) ROLES - R1: ASBR. Redistributes static 172.20.10.0/24 -> Null0 into OSPF as O E2. - R2: ABR + DR. Priority 100 forces DR election on the LAN segment. - R3: Internal Area 0 router. Default priority - becomes BDR. - R4: Internal Area 30 router. NODE COUNT (CML Free) - 4 counted iol-xe + 1 unmanaged switch (not counted) = 4 counted. 1 slot free. USE Boot the lab, wait ~2-3 min for OSPF convergence, then run: - show ip ospf neighbor (R2 has 3 neighbors: R1 DROTHER, R3 BDR, R4 P2P) - show ip ospf interface brief - show ip route ospf (R4 sees IA + E2 routes; R1 sees IA routes to Area 30) - show ip ospf database (LSAs by area) title: PingLabz OSPF Reference Lab version: 0.3.0
