F.3.1 Routing Protocol

In theory, any state-of-the-art routing protocol could be used for the virtual IP network. This section
describes how to set up the virtual router using the OSPF (Open Shortest Path First) routing protocol
because it is a commonly used protocol.
For the OSPF routing protocol, define an OSPF Area ID to use for the BCC-enabled resources in a
business continuity cluster. All nodes of every peer cluster in a given business continuity cluster
need to use the same OSPF Area ID. When deploying multiple business continuity clusters, use a
different OSPF Area ID for each one.
IMPORTANT: Do not use OSPF Area ID 0 for any of your business continuity clusters.

F.3.2 LAN Routers

For your LAN routers, you must define the OSPF Area ID to be used for each of your business
continuity clusters. For guidelines about OSPF Area IDs, see
page 170. The LAN routers are also where you define and handle the propagation of the routes to
services that are using virtual IP addresses.

F.3.3 Internal Router

Do not use a cluster node as a general purpose router. Make sure a default gateway is properly set
up, and the default route of the cluster node is configured accordingly.
Redistribute any routing changes for the cluster resources to your routing infrastructure but do not
redistribute routing changes somewhere in the LAN/WAN to the cluster nodes.
F.3.4 IP Addresses for BCC-Enabled Cluster Resources
Define an IP address range for your BCC-enabled resources. The IP addresses must be unique across
all peer clusters. When deploying multiple business continuity clusters, use a different IP address
range for each of them.
For example, you can specify an IP address range for each peer cluster that accommodates the nodes
and the master IP address of the cluster:
Cluster 1: 10.10.10.0/24
Cluster 2: 10.10.20.0/24
Cluster 3: 10.10.30.0/24
Cluster 4: 10.10.40.0/24
You can specify a different range to be used for all cluster resources in the business continuity
cluster:
Resources: 10.10.50.nnn/32
