No Supernetting in RIP

It isn't very often you learn something new about RIP, but here is something I found out today: NO SUPERNETTING WITH RIP!

R1(config)#int lo 100
R1(config-if)#ip address 100.0.0.1 255.0.0.0
R1(config-if)#int lo 101
R1(config-if)#ip address 101.0.0.1 255.0.0.0
R1(config-if)#int f2/0
R1(config-if)#ip summary-address rip 100.0.0.0 254.0.0.0
Summary mask must be greater or equal to major net
R1(config-if)#

    According to u, i completed the lab successfully. One thing i just want to share..

    R1----- R2

    Doing summarization on R1. After summarization, summary route is appearing in R2. But i want to block all the network expect summary route.. I used prefix list to block & successfully implemented.

    I just want to know, it it correct way to do so...???

    If only the summary route that you want to be sent to R2, then you could remove the subnets from the rip network list and redistribute only the static route.
