A sibling_addresses statement is required for each VLAN created with the zconfig
commands. The two addresses in the list indicate there are two switches in the Surviving Partner
group. The first address 10.0.0.30 and 11.0.0.30 are assigned to the switch on which the
configuration is being run. The remaining addresses are distributed to the switches that run
zspconfig -u on a first come, first serve basis.

The sibling_addresses command may also take a netmask operand similar to that given
to ifconfig. For example:

sibling_addresses: zhp0 = 10.0.0.30, 10.0.0.31 netmask
255.255.255.0;

sibling_addresses: zhp1 = 11.0.0.30, 11.0.0.31 netmask

255.255.255.0;

Virtual addresses should be setup for all VLANs that connect to

High Availability nodes. Usually this would include all VLANs
except the interconnect VLAN or VLANs connected to upstream

routers. It is possible that a setup would have VLANs that are
used for management only. Virtual addresses are setup as

follows:

virtual_address: zhp0 = 10.0.0.42 netmask 255.255.255.0;
virtual_address: zhp1 = 11.0.0.42 netmask 255.255.255.0;

Only a single address per VLAN is provided because this single address will move with the
current Master switch, and the netmask must be the same as that provided in the
sibling_addresses statement.

The last required section for the configuration is description of the ports. Particularly we need to
specify one of the following for all of the ports participating in the high availability setup. The
possible port types are:

interconnect - Ports connected between groups of Surviving Partner switches. VRRP
heartbeat messages are sent on the interconnect ports.

Crossconnect - Crossconnect ports are ports that are connected to other Surviving Partner
switches, that are not part of this Surviving Partner group. Crossconnect ports behave
differently then bonding ports. The links are not brought down temporarily, and VRRP runs
with the native MAC addresses to avoid MAC address duplication with the other VRRP
group.

RAINlink - Ports connected to RAINLink or bonding driver nodes. These ports contain
virtual addresses managed by VRRP. And during a failover event, the links are toggled
down to force failover to the Master switch.

Route - Ports connected to upstream routers. VRRP does not manage virtual IP addresses for
these links. Routing protocols must be used to instruct up stream routers of a different path
to get to the VRRP managed networks. These port types are currently not implemented.
