IP global parameters for routing switches

Ip routing features an ARP reply
Parameter Description Default See page
Address Resolution Protocol (ARP) A typical IP mechanism that routers use to understand the MAC address of the device around the network. The router transmits the Ip of the device within the ARP request and receives the device’s MAC address within an ARP reply. Enabled Configuring ARP parameters

Time for you to Live (TTL) The utmost quantity of routers (hops) by which a packet can pass prior to being discarded. Each router decreases a packet’s TTL by 1 before forwarding the packet. If reducing the TTL causes the TTL to become , the router drops the packet rather of forwarding it. 64 hops Begin to see the chapter “Configuring IP Addressing” within the Management and Configuration Guide.
Directed broadcast forwarding A directed broadcast is really a packet that contains all ones (or in some instances, all zeros) within the host area of the destination Ip. Whenever a router forwards this type of broadcast, it transmits a duplicate from the packet out all of its enabled IP interfaces.
