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]
user@Area-1-ABR# show protocols ospf
no-nssa-abr;
area 0.0.0.1 {
nssa;
interface ge-1/1/1.100;
