RIPv1 Design

• Note that the packet format wastes a lot of space

• There are a number of reasons for this

• • RIP was originally designed so that it could be used with non-IP networks
  • • This never really happened, as other protocols designed their own version of RIP
    • E.g., IPXRIP, XNS RIP, etc.
    • Eight empty bytes in each route entry are for support of the other addressing families
  • Fields tend to fall on 32-bit boundaries
  • • Easier for processing on 32-bit processors
