SOLUTION: Triggered Updates/Split Horizon for Preventing Two-hop Loops
"Split horizon" is a scheme for avoiding problems caused by including routes in updates sent to the router from which they were learned.
Version -- The RIP version number. The current version is 2.
Address family identifier -- Indicates what type of address is specified in this particular entry.
Route tag -- Attribute assigned to a route which must be preserved and readvertised with a route. The route tag provides a method of separating internal RIP routes from external RIP routes, which may have been imported from an EGP or another IGP.
IP address -- The destination IP address.
Subnet mask -- Value applied to the IP address to yield the non-host portion of the address. If zero, then no subnet mask has been included for this entry.
Next hop -- Immediate next hop IP address to which packets to the destination specified by this route entry should be forwarded.
Metric -- Represents the total cost of getting a datagram from the host to that destination.RIP 2 Packet Format
