Each NetRunner may belong to only one cluster. (NetRunner models
containing two LAN modules count as two nodes. The two LAN
modules can be assigned to one cluster and count as two nodes in that
cluster, or they can each be assigned to different clusters - and count
as one node in each cluster.)
D
A new NetRunner will only attempt connection via the WAN with
other NetRunners assigned to the default cluster name of None. To
connect a new NetRunner to a different cluster, its cluster name needs
to be changed. This procedure is described in the Integration Router
manual.
D
Each cluster may consist of up to 12 interconnected NetRunners. For
example, if you connect a new NetRunner to a WAN with 12 nodes
already in place, a request for connection by the new NetRunner will
be ignored, as each node's address table already holds the maximum of
11 other node addresses.
To add the new node to the network, the original 12 nodes need to be
partitioned into smaller clusters and the new NetRunner assigned to
one cluster or another. This is illustrated in the following figures.
