  3. RIP v1 • Default • No subnetmask • Onlyworkswith CLASSFUL networks(A, B, C based on the first 3 bits of the IP address) • Inboundinterfacemask is used – canhandlecontinoussubnets.

  4. RIP v2 • Can be protected with password (more secure) • More informationinpacket (administrativedistance) • Subnetmasksupport(VLSM ornotcontinousranges)
