Parameters
value: Bandwidth reference value in Mbps, ranging from 1 to 2147483648.
Use the
bandwidth-reference
for calculating link cost.
Use the
undo bandwidth-reference
By default, the reference value is 100 Mbps.
In the case no interface cost is specified in interface view or system view and
automatic cost calculation is enabled:
When the cost style is wide or wide-compatible, IS-IS automatically
■
calculates the interface cost based on the interface bandwidth, using the
formula: interface cost = bandwidth reference value/interface bandwidth, and
the maximum calculated cost is 16777214.
When the cost style is narrow, narrow-compatible, or compatible, if the
■
interface is a loopback interface, the cost value is 0; otherwise, the cost value is
automatically calculated as follows: if the interface bandwidth is in the range of
1 M to 10 M, the interface cost is 60; if the interface bandwidth is in the range
of 11 M to 100 M, the interface cost is 50; if the interface bandwidth is in the
range of 101 M to 155 M, the interface cost is 40; if the interface bandwidth is
in the range of 156 M to 622 M, the interface cost is 30; if the interface
bandwidth is in the range of 623 M to 2500 M, the interface cost is 20, and
the default interface cost of 10 is used for any other bandwidths.
