Information About IP Unnumbered Ethernet Polling Support
IP Unnumbered Ethernet Polling Support Overview
IP unnumbered support for serial interfaces is extended to Ethernet physical interfaces. Unnumbered Ethernet physical interfaces are used in the same manner as unnumbered serial interfaces. On a device, if two unnumbered interfaces inherit their addresses from the same loopback address and are connected to the same peer, this configuration is not supported.
The polling option enables the dynamic discovery of hosts (connected though the unnumbered interfaces) based on the Address Resolution Protocol (ARP) protocol.
