Routing
Routing is the process of selecting a path for traffic in a network or between or across multiple networks.
Internet Routing Registries
There are at least 25 IRRs registering and executing routing policies that
- offer public descriptions of the relationship between external and internal Border Gateway Protocol peers,
- offer Documentation,
- provide routing security,
- allow automatic generation of router configurations,
- provide a debugging aid,
- publish routing intentions,
- construct and maintain routing filters and router configurations, and
- share diagnostic and information service for general network management.[1]
Routing Incidents Types
Border Gateway Protocol (BGP) is a key tool for Internet connection redundancy, enabling data communications between large networks operated by different organizations. However, one bad move can lead to a major blackout.[2] Possible causes could be:
- Misconfiguration
- Malicious
- Targeted Traffic Misdirection
