destination IP address or sub-network is configured as an attribute in the IP
routing table.

The IP MTU in use is the lowest of:
• The interface IP MTU setting
• Any IP MTU specified by the selected route
• Any IP MTU specified by the MTU command

The recommended MTU size is 8972 bytes (in order to compensate for the IP
and ICMP headers).
