Hi khurram,
its seems to be that connected route are also redistribute in rip when u redist
ribute bgp in RIP may be due to some changes in IOS version 12.1, but it should
be of classful network as per requirement of RIP.
regards,
khalid

If RIP is not running on network 12.0.0.0, and you redistribute BGP as
mentioned, then it will appear in RIP domain.

Yakout,
Attached are the notes to your reply...
> 1) BGP AS number is incorrect, has to be 24 since you are redistributing
BGP
> 24, I asuume that was a typo.
Yes , it was a typo. corrected line 'redistribute bgp 1 metric 1'
> 2) If your network statement under RIP was "network 12.0.0.0", which is
not
> shown here..
No ! Network 12.0.0.0 is not in RIP. Its only in BGP, which implies it
will be
a 'connected' route in Routing Table and an entry will be created in BGP
Table with
nexthop 0.0.0.0
Do you expect RIP to advertise this route on redistributing bgp in RIP??
Comments appreciated
Thanks
Khurram.
