3.6.2 Maximum number of multihomed subnets

For a LAN multihomed connection, more than one IPv4 address or IPv6 address is set for one interface.

<Structure of this section>

(1) For IPv4

The following table describes the maximum number of multihomed subnets for IPv4.

(2) For IPv6

The table below describes the maximum number of multihomed subnets for IPv6. This maximum includes the number of link-local addresses. An interface must always be assigned one link-local address. Therefore, if only IPv6 global addresses are set for all interfaces, the actual number of IPv6 addresses that are set on the switch is 8, the number of automatically generated IPv6 link-local addresses plus one.
