In the exhibit, customers connected to Area 3 must have access to external prefixes received from
the data center connected to the router in Area 1. These configurations are currently applied to the
routers in Area 1:
{master:0}[edit]

}
{master:0}[edit]
lab@Area-1-External# show protocols ospf
area 0.0.0.1 {
