Re: Problem with routing protocol RIPng.

Fri Nov 23, 2012 10:06 am

Does anyone have the same problem with the RIPng?

So instead of connections, type "connect" are seen by the router "R2" as RIPng.
After turning off the router "R3" router "R2" loses network routing table, which wrong seen as "RIPng" but should it be a network "connect".
After reboot, RIPng protocol. Networks are visible again.


My question is as follows:
Do I have something misconfigured?
Are you perhaps a bug that should be reported to Support MT?
