Why each option
Intercluster Lookup Service (ILS) in CUCM supports two authentication methods: TLS certificates and passwords.
TokenID is not a supported authentication mechanism in CUCM ILS configuration.
While CUCM uses username/password in many contexts, ILS specifically does not use a 'username and secret key' combination as an authentication type.
TLS certificate-based authentication uses the CUCM cluster certificates to mutually authenticate ILS peers, providing strong cryptographic identity verification between clusters.
Password-based authentication uses a shared password configured on both clusters to authenticate the ILS connection, serving as a simpler alternative to certificate-based auth.
FQDN entries in DNS are used for server discovery/addressing, not as an authentication mechanism for ILS.
