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;
}
{master:0}[edit]
user@Area-1-External# show protocols ospf
area 0.0.0.1 {
stub no-summaries;
interface ge-1/1/1.100;
}
What must you change for these configurations to work?

Referring to the output in the exhibit, why does the router prefer the path toward interface ge-
0/0/0.0 for the 20.0.0.0/8 route?
