• The Expressway cluster name should be the routable FQDN used in the SRV records that address the cluster, and the same cluster name must be configured on every peer. in context
• To form a cluster you first create a cluster of one (the primary) and restart it before adding other peers. in context
• Cisco recommends forming the cluster with IP addresses in Permissive mode, then changing peer addresses to FQDNs, and then switching TLS verification mode to Enforce. in context
• Configuration is copied from the primary to the other peers about every two minutes, and changes can take up to about a minute to appear on all peers. in context
• Cluster TLS verification mode defaults to Permissive; Enforce requires valid peer certificates. in context
