It seems to me that you are trying to force traffic from AS 300 destined to
10.1.1.0/24 through AS 200, rather then directly to AS 100. If this is
correct you really don't need to do anything on R5. The following will
accomplish this:
//Assume R3 is neighor 3.3.3.3 for R1://
route-map pre-pend permit 10
match ip address prefix-list pre-pend
set community 100:10
!
!
route-map pre-pend permit 20
match ip address
!
!
ip prefix-list pre-pend seq 10 permit 10.1.1.0/24
access-list 1 permit any
!
!
//In your router bgp section//
neighbor 3.3.3.3 route-map pre-pend out
!
Assume R4 is neighbor IP address 4.4.4.4 for R3
Assume R3 is neighbor IP address 33.33.33.33 for R4
route-map pre-pend permit 10
match community 10:100
set as-path prepend 1000 2000 3000
!
!
route-map pre-pend permit 20
match ip address
!
!
ip prefix-list pre-pend seq 10 permit 10.1.1.0/24
access-list 1 permit any
//In your router bgp section//
neighbor 33.33.33.33 route-map pre-pend in
