When you did a "debug ip rip" what advertisement(s) did you see with either
of those two configurations?

Subject: RIP v2 auto-summary

When I enable no-auto-summary under rip version 2 and do a show ip rip
database. Why is there an entry of 172.29.0.0/16 being summarized.

How does the no-auto and auto work for Rip Version 2. The database and
route table look the same for either command

Thanks
