IP Connectivity CLI lab Analyze & fix

Multi-area OSPF: area 1 can’t reach area 0 — on the CLI

An ABR should be gluing area 1 to the backbone (area 0), but LSA Type 3 inter-area routes never show up on the far side. Investigate the ABR, find the misconfig, and get inter-area routes flowing. Type real Cisco IOS commands — abbreviations and Tab-completion work — to find the fault and fix it.
