This is actually Lab 3-7 in the Cisco CCNP ROUTE Lab book.
I have a router that is connecting the following networks
Loopback 101 10.1.1.101/30 Area 200
Loopback 105 10.1.1.105/30 Area 200
Loopback 109 10.1.1.109/30 Area 200
Loopback 113 10.1.1.113/30 Area 200
Through a virtual link to Area 0.
Simple enuff at this point.
Now an objective wants me to sumamrize the above netowk to the most efficient summary.
Okay, so I figure
area 200 range 10.1.1.96 255.255.255.224
Should do the trick...
No dice.. All the networks are still showing up in routing tables of all three routers..
I bang my head against this problem for like 30 minutes, wondering was there something special about virtual links that would "break" summaries?
Then, I finally caught that I had accidentally put in the command
netw 10.1.1.96 0.0.0.31 area 100
instead of:
netw 10.1.1.96 0.0.0.31 area 200
So I guess the lesson is this.. When you think you have the concepts down pretty good, and something does not work like you think it should, (especially you first few times configuring it) go back and check that you did not fat finger a command.
