BGP Routing

Border Gateway Protocol (BGP) Routing determines the best network routes for data transmission on the internet. The internet consists of thousands of private, public, corporate, and government networks linked together through standardized protocols, devices, and communication technologies. When you browse the internet, data travels across multiple networks before reaching its destination. BGP looks at all the available paths that data could travel and selects the best route. For instance, when a user in the United States loads an application with origin servers in Europe, BGP makes that communication quick and efficient.

Equinix assigns a private Autonomous System Number (ASN) for your LAN. BGP policy is used to select:

• Default Routes
• Full Routes
• Default + Full Routes

IP Subnet Sourcing

The available options for the LAN IP subnets used by EIA services are described here:

Up to 100 subnets can be configured per EIA service. Subnets may include a mix of Equinix-assigned and Customer-assigned IP addresses. Mixing Equinix-assigned and Customer-assigned addresses on the same EIA service is permitted only when the announcing ASN is provided by Equinix. Equinix-assigned addresses cannot be announced using a customer ASN.

Equinix-assigned IP Addresses

Provided by Equinix, you must purchase additional LAN IP subnets from Equinix for this option.

Customer-assigned IP Addresses

Provided by the customer, IP addresses must be at least IPv4 /24 or IPv6 /48. For customer-assigned IPs, customers can use either their own public ASN (only for EIA over Dedicated variant) or a private ASN assigned by Equinix.

Single-Port Architectures

For Single-Port BGP, Equinix assigns a private Autonomous System Number (ASN) for the LAN, and a default WAN IP subnet of /30 for IPv4 addresses and /64 for IPv6 addresses. A BGP-capable Layer 3 device is required.

Dual-Port Architectures

By default, Equinix assigns a private Autonomous System Number (ASN) for the LAN, and two /30 IPv4 WAN subnets and two /64 IPv6 WAN subnets. A pair of Layer 3 devices for the dual-homed setup is required.

Traffic Engineering - BGP Communities

The following communities are available to all BGP users:

• Lower local preference

  • 65502:80 Set local preference to a lower value than standard customer (above peers, multi homed customer scenario)

• Remotely Triggered Black Hole

  • 65535:666 Blackhole a single host within customer’s ranges

If you are using BGP and bringing your own IP addresses, you can control how your routes are announced out of AS15830, and how traffic should flow into your network. Equinix offers the following communities for you to tag onto your prefixes.

• Prepend (Customer-assigned IP addresses only)

  • 65501:nnnn Prepend 1x AS15830 towards a provider or IXs in a metro
  • 65502:nnnn Prepend 2x AS15830 towards a provider or IXs in a metro
  • 65503:nnnn Prepend 3x AS15830 towards a provider or IXs in a metro
  • 65505:nnnn (to be deprecated) Prepend 5x AS15830 towards a provider or IXs in a metro

• Do not announce (Customer-assigned IP addresses only)

  • 65509:nnnn Do not announce the prefix towards a provider or IXs in a metro
  • 65509:300 Do not announce to any peer globally
  • 65509:400 Do not announce to any ISP provider globally

The suffix ‘nnnn’ can be either the provider ASN or one of the following:
