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: 

enable
configure terminal
  router bgp 10
  ! no bgp default ipv4-unicast
  bgp router-id 192.168.1.1
    !
    neighbor 2001:192:168:3::2 remote-as 20
      address-family ipv6 unicast
        network 2001:10:100:100::/64
        network 2001:10:100:200::/64
      neighbor 2001:192:168:3::2 activate 
    neighbor 192.168.3.2 remote-as 20
      ! address-family ipv4 unicast 
      network 10.100.100.0/24
      network 10.100.200.0/24

      neighbor 192.168.1.2 activate
  end


ISP2:

  router bgp 20

    neighbor 2001:192:168:3::1 remote-as 10

  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: 

enable
configure terminal
  router bgp 30
  ! no bgp default ipv4-unicast
  bgp router-id 192.168.1.2
    address-family ipv6 unicast
      network 2001:10:1:1::/64
      network 2001:10:1:2::/64
      neighbor 2001:192:168:1::1 remote-as 10
      neighbor 2001:198:168:1::1 route-map PREPEND out
      neighbor 2001:192:168:1::1 activate
    route-map PREPEND permit 10
    set as-path prepend 30 30 30 30 30
    end

configure terminal
  router bgp 30
  ! no bgp default ipv4-unicast
  bgp router-id 192.168.1.2
    neighbor 192.168.1.1 remote-as 10

    network 10.1.2.0/24
    neighbor 192.168.1.1 activate
    route-map PREPEND permit 10
    set as-path prepend 30 30 30 30 30
    end

configure terminal
  router bgp 30
  ! no bgp default ipv4-unicast
  bgp router-id 192.168.1.2
    neighbor 2001:192:168:2::1 remote-as 20
      address-family ipv6 unicast
        network 2001:10:1:1::/64
        network 2001:10:1:2::/64
      neighbor 2001:192:168:2::1 activate  
    neighbor 192.168.2.1 remote-as 20
      ! address-family ipv4 unicast 
      network 10.1.1.0/24
      network 10.1.2.0/24
      neighbor 192.168.2.1 activate
  end

Cek

! perhatikan AS 30 di tambahkan 5x ke routing ke arah AS 10
!
show ip bgp

show ip route
