7.12.5 (Optional) Configuring IPv6 IS-IS Attributes for Interfaces
on Different Types of Networks
Different IS-IS attributes can be configured for different types of network interfaces.
Context
The establishment modes of IS-IS neighbor relationships are different on a broadcast network
and on a P2P network. Different IS-IS attributes can be configured for interfaces on different
types of networks.

4. Run:
ipv6 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.
NOTE
The auto-cost enable command can be run on Eth-Trunk interfaces as same with on physical
interfaces. If the command is run on an Eth-Trunk interface, the bandwidth of the Eth-Trunk interface
is equal to the total bandwidth of all its member interfaces.
If the cost-style is narrow, narrow-compatible, or compatible, the cost of each interface is
based on costs listed in
Table 7-2 Mapping between IS-IS interface costs and interface bandwidth

NOTE
To change the cost of a loopback interface, run the isis ipv6 cost command only in the loopback
interface view.
