It combines the advantages of two kinds of link-state and distance vector routing protocol
Open and can specify the network, specify the network there are a variety of ways
Neighbor Table

Topology table

Routing Table
FD (feasible distance):
The local router to the destination metric (cost) is the Metric value
AD (Notice distance):
Next-hop router to measure destination
Successor can be understood as the optimal path
FD lowest value
Feasible successor will be appreciated that suboptimal path
FD AD value is less than the value of the successor
Note: BW minimum bandwidth
In fact, the minimum bandwidth (BW) and load (DLY)

CDP Neighbor Discovery Protocol
Cost load balancing: default supports four different different versions of IOS
v * S FD> FS FD rounding
Feasible successor FD / successor FD = n (n + 1 if it is an integer, rounding up if the decimal)
The method is similar to the rip, you must specify MD5 authentication, or may fail
