Important Considerations

The system uses the ARP cache to find the MAC addresses that correspond to the IP addresses of hosts and other routers on the same subnets. Each device that participates in routing maintains an ARP cache, which is a table of known IP addresses and their corresponding MAC addresses.

The first line in the output (the status line) indicates whether IP routing is enabled (in-band only):

IP interface options (such as ICMP router discovery) appear under ip interface detail and are set on a per-interface basis. The second status line indicates the number of entries in the ARP cache.
