+## IPv6 Router Advertisements with radvd
+
+The libvirt_manager role can automatically configure IPv6 router advertisements using the `radvd` role. This is useful for providing SLAAC and/or DHCPv6 configuration to VMs on IPv6-enabled networks.
+
+To enable radvd, define `cifmw_libvirt_manager_radvd_networks` with a list of network configurations:
+
+```yaml
+cifmw_libvirt_manager_radvd_networks:
+  - name: cifmw-testnet1
+    adv_managed_flag: true
+    adv_other_config_flag: true
+    prefixes:
+      - network: "2001:db8:1::/64"
+```
+
+For complete documentation on available parameters and configuration options, refer to the [radvd role documentation](../radvd/README.md).
