Explanation:
When configuring Intercluster Lookup Service (ILS) in Cisco Unified Communications Manager (CUCM), two types of authentication are supported to secure communication between clusters:
TokenID (A): This is a unique identifier used for authentication between clusters in ILS. It helps to ensure secure communication by verifying that the clusters are authorized to exchange information.
TLS certificates (C): Transport Layer Security (TLS) certificates are used for encrypted communication between clusters. TLS provides secure encryption of the data transmitted between CUCM clusters, ensuring that the ILS data is protected during transit.
- Use TLS authentication between clusters in the ILS network.
- Use password authentication between remote clusters in the ILS network.
- Use TLS and password authentication to setup a ILS network using common Certificate Authority (CA) signed certificates without exchanging self-signed certificates between clusters.
