I am going to create flash cards for my CCIE lab studys. A sample question could look like this:
Routers R1 and R2 are EIGRP neighbors. 220.127.116.11/24 is the transit link between them.
R1 also has a loopback with the IP-address 18.104.22.168/24. The default settings are
enabled for EIGRP and the correct network statements are in place. What netmask will R2
have for R1’s loopback?
The netmask is 255.255.0.0 or /16 since auto-summary is on by default.
I am going to create the flashcards in Anki, if there is interest I will make it publically available for download and it will be updated whenever I add content to it.
