IGP, EGP (Routing Protocols)

The steps for handling any router data and finding the path, primarily across Autonomous Systems (AS, Networking), we need to:

1. Collect info about the network
2. Process the data
3. Generate that info to the Routing Table

We have multiple standard routing protocols:

• Interior routing protocols
  • May be called Interior Gateway Protocols (IGP)
  • Open Shortest Path First (OSPF) (interior, may be used in an ISP Autonomous Systems (AS, Networking) or company network)
• Exterior routing protocols
  • May be called Exerior Gateway Protocls (EGP)
  • BPG used between AS's
• iBGP Route Redistribution
  • Used to redistribute BGP routes within the AS
