The system view is displayed.
2. Run:
isis [ process-id ]
The IS-IS view is displayed.
3. Run:
circuit-cost cost [ level-1 | level-2 ]
The global IS-IS cost is configured.
You can use the circuit-cost command to configure the costs of all interfaces at a time.
l Enable IS-IS to automatically calculate interface costs.
1. Run:
system-view
The system view is displayed.
2. Run:
isis [ process-id ]
The IS-IS view is displayed.
3. Run:
bandwidth-reference value
The reference value of the bandwidth is configured. By default, the bandwidth
reference value is 100 Mbit/s.
4. Run:
auto-cost enable
The interface is configured to automatically calculate its cost.
The configuration of the bandwidth reference value takes effect only when the cost type is
wide or wide-compatible. In this case, Cost of each interface = (Value of bandwidth-
reference/Interface bandwidth) x 10.
If the cost-style is narrow, narrow-compatible, or compatible, the cost of each interface is
based on costs listed in Table 6-1.
