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?

• A.  Configure the ABR in Area 1 for a default LSA with a default-metric of 10 and no- summaries.
• B.  Configure the ABR router in Area 1 to support a virtual link.
• C.  Delete no-summary-lsa from the ABR router in Area 1.
• D.  Configure the external router in Area 1 for NSSA.

In the exhibit, R5 is receiving five 200.1.1.x routes from the RIP router, and is advertising them into Area 1 using an export policy. You want to summarize the RIP routes into Area 0 with the most specific prefix.
Which configuration will accomplish goal?

• A.  [edit protocols]
  user@R1# show
  ospf {
  area 0.0.0.0 {
  area-range 200.1.1.0/28;
  interface ge-0/0/1.0;
  interface ge-0/0/2.0;
  interface lo0.0;
  }
  area 0.0.0.1 {
  nssa {
  default-lsa type-7;
  }
  interface ge-0/0/3.0;
  }
  }
• B.  [edit protocols]
  user@R1# show
  ospf {
  area 0.0.0.0 {
  area-range 200.1.1.0/29;
  interface ge-0/0/1.0;
  interface ge-0/0/2.0;
  interface lo0.0;
  }
  area 0.0.0.1 {
  nssa {
  default-lsa type-7;
  }
  interface ge-0/0/3.0;
  }
  }
• C.  [edit protocols]
  user@R1# show
  ospf {
  area 0.0.0.0 {
  interface ge-0/0/1.0;
  interface ge-0/0/2.0;
  interface lo0.0;
  }
  area 0.0.0.1 {
  nssa {
  default-lsa type-7;
  area-range 200.1.1.0/28;
  }
  interface ge-0/0/3.0;
  }
  }
• D.  [edit protocols]
  user@R1# show
  ospf {
  area 0.0.0.0 {
  interface ge-0/0/1.0;
  interface ge-0/0/2.0;
  interface lo0.0;
  }
  area 0.0.0.1 {
