Re: OT - Fridays Puzzle

No problems, as long as we are learning, it's cool.

NOW, R2 is using network 2.0.0.0 as the candidate default correct?

*Puzzle #2*

Configure R2 such that it does NOT use network 2.0.0.0 as the candidate
default.

*Restrictions:*

R2 should have network 2.0.0.0 in its routing table reachable via R1.
DO NOT configure R1.
You should use an access-list on R2.
DO NOT use another global config command on R2 besides the access-list to
accomplish this task.
DO NOT use PBR, or IP SLA.
DO NOT configure another interface on R2.
