7.2 establishing ebgp peering

hi

in the result of show ip bgp in R1

we see he receive the same route from BB1 and BB3 and one we be preferred

my issue is I need the correct config of BB3 and BB1

interface Loopback0ip address 28.119.16.1 255.255.255.0
ipv6 address 2001:28:119:16::1/64
!
interface Loopback1
ip address 28.119.17.1 255.255.255.0
ipv6 address 2001:28:119:17::1/64
!
interface Loopback10
ip address 30.0.0.1 255.255.0.0
ipv6 address 2001:30::1/64
ipv6 rip RIPng enable
!
interface Loopback11
ip address 30.1.0.1 255.255.0.0
ipv6 address 2001:30:1::1/64
ipv6 rip RIPng enable

Rack1R1#show ip bgp
BGP table version is 33, local router ID is 150.1.1.1
Status codes: s suppressed, d damped, h history, * valid, > best, i - internal,
r RIB-failure, S Stale
Origin codes: i - IGP, e - EGP, ? - incomplete

*>i28.119.16.0/24 204.12.1.254 0 100 0 54 i
* i                          54.1.1.254 0 100 0 54 i

so from here we know that R1 receive the network 28.119.16.0 from BB1 and BB3

if you go to that link http://www.ine.com/downloads/bb1.txt

I don't find any int loopack with ip address that belong to network 28.119.16.0/24

I need just correct initial config bb1 , bb2

thanks.
