Ada tiga (3) ISP
ISP1:
IP 192.168.1.1/24 menuju ISP3 IP 192.168.3.1/24 menuju ISP2 AS 10 IP 10.100.100.0/24 IP 10.100.200.0/24
ISP2
IP 192.168.2.1/24 - menuju ISP3 IP 192.168.3.2/24 - menuju ISP1 AS 20 IP 10.10.10.0/24 IP 10.10.20.0/24
ISP3 (kita)
IP 192.168.1.2/24 - menuju ISP1 IP 192.168.2.2/24 - menuju ISP2 AS 30 IP 10.1.1.0/24 IP 10.1.2.0/24

BGP Peering
Consider that IP connectivity between ISPs edge routers and Our Core router is already set up and working properly. So we can start to establish BGP peering to both ISPs.
ISP1:
vtysh
configure terminal
router bgp 10
bgp router-id 192.168.1.1
no synchronization
bgp log-neighbor-changes
network 10.100.100.0/24
network 10.100.200.0/24
neighbor 192.168.3.2 remote-as 20
neighbor 192.168.3.2 password $AP7i1
neighbor 192.168.1.2 remote-as 30
neighbor 192.168.1.2 password $AP7i1
end
ISP2:
vtysh
configure terminal
router bgp 20
bgp router-id 192.168.2.1
no synchronization
bgp log-neighbor-changes
network 10.10.10.0/24
network 10.10.20.0/24
neighbor 192.168.3.1 remote-as 10
neighbor 192.168.3.1 password $AP7i1
neighbor 192.168.2.2 remote-as 30
neighbor 192.168.2.2 password $AP7i1
end
Main / Backup Link Setup di ISP3
Lakukan
- accept network kita sendiri
- drop semua tabel IP lainnya, karena kita tidak mau menjadi transit provider
- BGP AS prepend - menaikan AS path ke salah satu ISP (disini ISP1)
ISP3:
vtysh
configure terminal
router bgp 30
bgp router-id 192.168.1.2
no synchronization
bgp log-neighbor-changes
network 10.1.1.0/24
network 10.1.2.0/24
neighbor 192.168.2.1 remote-as 20
neighbor 192.168.2.1 password $AP7i1
neighbor 192.168.1.1 remote-as 10
neighbor 192.168.1.1 password $AP7i1
neighbor 198.168.1.1 route-map PREPEND out
route-map PREPEND permit 10
set as-path prepend 30 30 30 30 30
end
Cek
! perhatikan AS 30 di tambahkan 5x ke routing ke arah AS 10 ! show ip bgp
show ip route show ip bgp 10.100.1000.0/24 show ip bgp neighbors 192.168.2.2 advertised-routes show ip bgp neighbor 192.168.1.1 routes show bgp ipv4 unicast neighbors show bgp ipv4 unicast summary
