AS7195 – BGP COMMUNITIES

EdgeUno is an Internet Service Provider and Managed Services company that provides infrastructure at national or global scale. This document provides information about our routing policy, and how customers can control their prefixes inside our network.

EdgeUno have a selective peering policy, and our network information can be found updated at https://www.peeringdb.com/asn/7195

Origin Communities

Origin communities are used to identify the region in which a prefix was learned and if a prefix was learned from a customer.

Local Preference

By default, all received customer routes are assigned a local preference of 300 in EdgeUno Backbone. Customer can change this preference using the following BGP communities:

Traffic Engineering

The use of this communities allow customer to prevent their prefixes from being advertised to peers/transits or to a complete region. Not all our peers are eligible to traffic engineering. (consult network engineering for specific ASNs)

Below we have a table with a list of peers and transit connections that accept this.
Traffic engineering communities are formatted AAYZZ:ASN where:

• AA Private code and will be always 64.
  
• Y Action code where:
  • 0 – Suppress the announce
    
• ZZ Country Code where:
  • 01 – USA
