You are running into the old "redistribute protocol for routes that are
connected" problem. <g>
The problem is that the 200.200.200.0 network is a connected interface
on the same router on which both RIP and BGP are running. The IOS
protects itself by being selective about what it is going to allow into
redistribution or all sorts of messy internal loops will develop.
Now, if the 200.200.200.0 route came into your routing table via RIP
from another router, the "metric" keyword would work just fine. In my
example below, both routers are running RIP and BGP. Router R2 is
advertising network 200.200.200.0 to R6 via RIP.
R6--172.150.200.0--R2--200.200.200.0
on R6:
router rip
network 172.150.0.0
!
router bgp 6
bgp log-neighbor-changes
redistribute rip metric 5
neighbor 172.150.200.2 remote-as 1
!
