Khurram,
In your scenario;
1) BGP AS number is incorrect, has to be 24 since you are redistributing BGP
24, I asuume that was a typo.
2) If your network statement under RIP was "network 12.0.0.0", which is not
shown here..
Then the answer to your question is, No the network will not be advertised
by RIP.
The reason is as I mentioned before in my previous email.
Another thing, when you redistribute BGP into any IGP, it will only
redistribute EBGP and Locally originated routes (with next hop 0.0.0.0) it
will not redistribute iBGP routes (marked with i in BGP table)
I am not sure of the reason behind that, but I guess to prevent loops,
assuming that iBGP routes will not be synched untill they are known via IGP
in the first place.
HTH
Yakout

Asim,
Appreciate your time , but this is not the question i asked. Original
question is:
"When you redistribute BGP in another protocol, does the Router
redistributes Routes
from "BGP Table" or it picks all installed 'B' routes from Routing table
and start
advertising in RIP domain"
Lemme give you an example
int loop0
ip address 12.0.0.1 255.255.255.0
router rip
redistribute bgp 24 metric 1 <---- redistributing BGP in RIP
network x.x.x.x (rip network).
.
.
router bgp 1
network 12.0.0.0 mask 255.255.255.0 <---- BGP will add 12.0.0.0/24 in BGP
Table
.
Do you expect 12.0.0.0 to be advertised on RIP interfaces? If not, why not?
Appreciate your help.
Thanks
Khurram.
