Considerations For Clustering - Nokia Voyager Reference Manual

Configuring Traffic Management
Note
All cluster nodes must use the same mode.
You can change the cluster mode without interrupting traffic flow through the
cluster. Use Cluster Voyager or the CCLI to change the mode on all the nodes
simultaneously.

Considerations for Clustering

Note
For information about the requirements for using VPN-1/FireWall-1 in an
IPSO cluster, see
When you configure an IPSO cluster, take into account the considerations
explained in the following sections.
Network Environment
Cluster nodes cannot use dynamic routing—that is, no routing protocols
!
can be enabled.
Devices that need to send traffic through a cluster must have a static route
!
that uses the appropriate cluster IP address (internal or external) for the
route's gateway address. For example, a router on the internal side of a
cluster should use an internal cluster IP address as the gateway address.
! If you use multicast mode, adjacent devices (either connected directly or
through a switch or hub) must be able to accept ARP replies that contain a
multicast MAC address. See
information about configuring interfaces for instructions about how to
configure a Nokia appliance to accept these replies.
Note
If there is no router between the cluster and host systems (PCs or
workstations), the hosts must be able to accept ARP replies with
