IP Interface Maximums Clarification
In the following sections, the formulas refer to "#IP Interfaces" count and not the
count of IP addresses, which can be greater if you use IP multinetting with either
IPv4 or IPv6. To clarify, if you use multinetting or IPv4 and IPv6 dual stack on a
VLAN, the consumption of routable MAC resources is as follows:
- IPv4 address (primary) consumes one entry of routable MACs
- IPv4 address (primary) + any number of secondary addresses (multinetting)
consumes one entry of routable MACs
- IPv6 interface (link-local) consumes one entry of routable MACs
- IPv6 interface (link-local) + any number of global addresses consume one entry
of routable MACs
- IPv4 address (in any combination) + IPv6 interface (in any combination) consumes
one entry of routable MACs
