Huawei S1720 Series Configuration Guide

There is no limit on costs of interfaces or route costs. The cost of a route received
by an interface is the actual cost.
– If the cost style is wide-compatible or wide, the cost of the interface ranges from 1 to
16777215. When the cost is 16777215, the neighbor TLV generated on the link cannot
be used for route calculation but for the transmission of TE information. The maximum
cost of a received route is 0xFFFFFFFF.
