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?

  1. Configure the ABR router in Area 1 to support a virtual link.

  2. Delete no-summary-lsa from the ABR router in Area 1.

  3. Configure the external router in Area 1 for NSSA.

  4. Configure the ABR in Area 1 for a default LSA with a default-metric of 10 and no- summaries.
