Usage Guidelines

Usage Scenario

To enable the IS-IS process to advertise link attributes, run the cost-style command in the IS-IS view to set the cost type of IS-IS packets to wide, compatible, or wide-compatible.

This command is used to control the attribute advertisement of TLV 22, and the IPv4 address family of the corresponding link must be active.

Example

# Enable the IS-IS process to advertise link attribute-related TLVs on the LSP.
