Interkoneksi BGP Routing

Sebelum kita memulai interkoneksi BGP antar ASN dibeberapa router, kita akan membuat contoh identifikasi suatu Router dan ASN (Public):

SANDYA: AS141626 - 10.212.212.9/30

TGR: AS65106 - 10.212.212.10/30 ( SANDYA-IX + CONTENT )

# Konfigurasi Route-Map IN #
route-map TGR-IN permit 10

large-community 141626:141626:1000 141626:212:1 141626:141626:65106
set local-preference 200
exit

# Konfigurasi Route-Map OUT # 
route-map TGR-OUT permit 10
ip address prefix-list SANDYA
large-community 141626:141626:141626
exit

route-map TGR-OUT permit 500
ip address prefix-list SANDYA-IX
exit

route-map TGR-OUT permit 1000
match large-community CONTENT
exit
