RIP Packet Fields Description
Command:
- Indicates that the packet is a request or a response. The request command requests the responding system to send all or part of its routing table. Destinations for which a response is requested are listed later in the packet. The response command represents a reply to a request or, more frequently, an unsolicited regular routing update. In the response packet, a responding system includes all or part of its routing table. Regular routing update messages include the entire routing table.
Version number:
- Specifies the RIP version being implemented. With the potential for many RIP implementations in the Internet, this field can be used to signal different, potentially incompatible, implementations.
