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.

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)
