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 = 10.0.0.43 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 rain link 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.
