Hi,

I have some questions about the configuration for
Cyscoexpert Sample Lab.

First: for question 5 under C.1

5. R1 should not see a default route from R2.

How has it been implemented?

I think it's implemented by configured area 12 as
NSSA.

Am I right?

Second: for question 3 under E.3.

3. The rest of the routing domain should only see one
route to these network.

I think it has been done by:

ip summary-address eigrp 100 220.1.0.0 255.255.252.0 5

Am I right?

If so, that means when we use ip summary-address eigrp
command, it will only advertise the summary adress,
like summary-only under BGP. Is it right?

3. Why has 0.0.0.0 been used as wildcard-mask all the
time? What's the advantage?

Thank you for help.

Best Wishes,
Peng Zheng
