3Com 4500G Family Configuration Manual page 366

Configure route redistribution on Switch B to make RIP 200 redistribute direct routes and routes
from RIP 100. Thus, Switch C can learn routes destined for 10.2.1.0/24 and 11.1.1.0/24, while
Switch A cannot learn routes destined for 12.3.1.0/24 and 16.4.1.0/24.
Configure a filtering policy on Switch B to filter out the route 10.2.1.1/24 from RIP 100, making the
route not advertised to Switch C.
