+-> **Note:** This resource should only be created **once**.
+It's used to configure static (not object) options in `protocols iccp` block.
+
+Configure static configuration in `protocols iccp` block.
+
+## Example Usage
+
+```hcl
+# Configure protocol ICCP
+resource "junos_iccp" "iccp" {
+  local_ip_addr                   = "192.0.2.1"
+  authentication_key              = "a_key"
+  session_establishment_hold_time = 300
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+- **local_ip_addr** (Required, String)  
+  Local IP address to use by default for all peers.
+- **authentication_key** (Optional, String, Sensitive)  
+  MD5 authentication key for all peers.
+- **session_establishment_hold_time** (Optional, Number)  
+  Time within which connection must succeed with peers (45..600 seconds).
+
+## Attributes Reference
+
+The following attributes are exported:
+
+- **id** (String)  
+  An identifier for the resource with value `iccp`.
+
+## Import
