Ohhh I'm sorry I meant to say 10.2.0.0/16
And not 10.2.0.0/24; but the concepts and the Debugs should be useful

Caffeine had not kick in yet

Hi Roman,

I would think that the configuration is OK, but in order to generate the
summary you need to have the 10.2.0.0/24 or longer match in your routing
table in order to generate that summary route

10.1.1.0/24  10.2.0.0/24, but yet is in the Mayor Class
Network. RIP v2 supports VLSM


Interface                  IP-Address      OK? Method Status

Ethernet0/0                192.168.12.5    YES NVRAM  up

The example for RIP summarization in the Cisco configuration guide has this
example:

interface Ethernet1
ip address 10.1.1.1 255.255.255.0
ip summary-address rip 10.2.0.0 255.255.0.0
no ip split-horizon

router rip
network 10.0.0.0

Why would you summarize and exclude the IP range of the interface? Is this
an error or is there a good reason to do this?
