12.2.2 Retrieving LIS Parameters
The LIS is an important CIP concept. It is a group of IP machines
configured as members of the same IP subnet. In other words:
they share the same IP network and subnetwork numbers.
In most cases this LIS will be a corporate LAN/WAN environment,
which is interconnected via the DSL/ATM network.
In order to be able to properly configure your STPro for sharing
the same logical IP subnet, you must know the following LIS
parameters:
 The IP network number
 The IP subnetwork number
 The remote access router's RFC1577/RFC2225 compliancy
state
 The remote access router IP address, in the case it is not
RFC1577/RFC2225 compliant.
Of course, in case you know the IP address of one member of the
LIS, and the associated netmask, you also have enough
information.
For an existing LIS, you must configure the STPro CIP settings,
according to the existing LIS parameters.
If the default CIP member's IP parameters, and the CIP
connection's remote IP address, configured in the STPro, match
with these parameters, nothing needs to be configured.
However, make sure that the CIP member's local IP address is not
ambiguous within the LIS.
In the case of creating a new LIS, you are recommended to use
the default CIP configurations of the STPro. In case the remote
access router is also a STPro, best results are assured.
Note: Both ends of the LIS must be properly configured for connectivity,
inclusive the routing tables.
