Configuring OSPF - Summarization Lab

As the CCIE Lab exam requires you to the think outside the box a bit, I will do the same on this lab. Here is a simple topology and the basic start up configuration.

Objectives:

  • Summarize 192.168.1.2/32 from Area 2 as 192.168.1.0/24 into area 0.

Restrictions:

  • Do not use area-range command or summary-address to summarize the routes into Area 0.
  • R3 and other routers in Area 0 or any new additional areas should only have the summary address to reach 192.168.1.2. 
  • If prefix 192.168.1.2/32 is withdrawn (i.e shutdown loopback0 on R2) from R1 OSPF database then 192.168.1.0/24 should not be summarized/advertised into area 0.
