Subject: ODR Problem!!!
Hi Group,
I need your help with the following scenario:
R1-----------------------------------R2
CDP is enable and it is working perfectly, I think so!!!
R1 only has ODR enable and its has 3 subnets conected directly.
R2 has OSPF and ODR, but R2 doesn4t receive the 3 routes of R1.
I really don4t know What I am doing wrong!!!
The debug show the following message:
R2:
R2#sh logging
Syslog logging: enabled (0 messages dropped, 1 messages rate-limited, 0
flushes, 0 overruns)
Console logging: level debugging, 72 messages logged
