Enhancing IS-IS network security
To enhance the security of an IS-IS network, you can configure IS-IS authentication. IS-IS authentication
involves neighbor relationship authentication, area authentication and routing domain authentication.
Configuration prerequisites
Before this configuration, complete the following tasks:
• Configure network layer addresses for interfaces, and to make sure that all neighboring nodes can
reach each other at the network layer.
• Enable IS-IS.

authentication succeeds, it forms the neighbor relationship with the peer.
The authentication mode and password at both ends must be identical.
