load

bandwidth

hop count

reliablity
usually refers to the bit error rare of rach network link
delay

defining a maximum

The packets flooded when a toplogy change occues,causing network routers to ipdate their topological database and recelculate routes
split horizon
This prevents sending infomation about a route back out the same interface that originally learned about the route.
holddwon timer
For given period,this cause the router to ignore any updates with poorer metrics to a lost network.
