IPv4 Default Metric for Default Routes for Layer 2 + Static Routing
An IPv4 default route can be assigned on in-band interfaces statically or by a
DHCP server. The following behavior is supported:
• The default metric for static assignment is 1
• The default metric for DHCP assignment is 253
The maximum metric value is 255.
NOTE: The same metric values are used for an IP default gateway on an OOB
interface.
If both an IPv4 default gateway on an OOB interface and a default route on
an in-band interface are both assigned, the selection for the active default
gateway / route is performed according to the following criteria:
• The lower metric is preferred regardless of the default gateway / route
assignment method (static or DHCP assignment).
• If two entries have the same metric, the IPv4 default gateway assigned to
an OOB interface is preferred
ARP
The Address Resolution Protocol (ARP) converts IP addresses into physical
MAC addresses. ARP enables a host to communicate with other hosts when
their IP addresses are known.
