Enabling ICMP Router Discovery globally
About this task
Enable Router Discovery globally so that the device supports Router Discovery. Use ICMP Router Discovery to enable hosts attached to the broadcast network to discover the IP addresses of their neighboring routers.
If you enable ICMP Router Discovery globally, you automatically enable it for all VLANs. If you do not require ICMP Router Discovery on a specific VLAN, you must manually disable the feature.
