Installing the Router on a Network
After a router is physically attached to a network, and powered-up, it must be
logically installed on the network. You can install a router using a network
management tool, such as OpenLNS CT.
Alternatively, you can use a custom network management tool that uses the
router network management messages defined in Chapter 7; this method is
recommended only for very simple networks with no more than a few routers
because of the complexity of calculating timing parameters and forwarding tables
for complex networks.
Router Installation with OpenLNS CT
The OpenLNS Commissioning Tool (OpenLNS CT) is an end-user tool that
supports installation of routers and application devices. See the OpenLNS CT
User’s Guide for a description of router installation.
Important: Before commissioning the router from OpenLNS CT, be sure that
you have programmed both halves of the router (for example, see Configuring a
Series 5000 Half-Router) and that the reset signals for both halves are tied
together (for example, see RST~).
Router Installation with Network Management
Messages
You can install routers using the network management messages described in
Chapter 7, Network Management Messages, and in Appendix B of the Neuron
Chip Data Book, but this process is only recommended for simple networks with
few routers. The process is similar to application device installation described in
the OpenLNS CT User’s Guide.
To install a router with network management messages, follow these steps:
1. Change the router state to Unconfigured using the Set Node Mode
network management message.
2. Assign one or two domains, subnets, and node IDs to both sides of the
router using the Update Domain network management message.
When installing the router in one domain, the same domain must be
assigned to both sides.
When installing the router in two domains, the same domain must be
assigned as the first domain on both sides, and the same domain must be
assigned as the second domain on both sides.
3. Select a routing algorithm for both sides of the router using the Write
Memory network management message. Both sides must be set to use
the same algorithm.
4. For configured routers, load the group and subnet routing tables on both
sides of the router using the Group or Subnet Table Download network
management message. There are 255 forwarding flags for subnets and
255 forwarding flags for groups on each side for each domain.
