Setup Hints
This section contains hints for setting up a BayStack router.
• Bay Networks recommends that you first install a BayStack router in the same
site as your BootP server, Site Manager workstation, and other Bay Networks
routers to test the software image, configuration file, and routing path. This
test provides you with the startup and troubleshooting experience you need to
perform these tasks on routers at remote sites. After you perform the test,
move the test router to the remote location, modify the configuration file for
that router, and set up the new paths.
• After you build and test the remote router configuration file, make copies of it
on the Site Manager workstation. Then, modify the copies for each BayStack
router in your network, rather than starting over. To avoid mix-ups, ensure that
the file name you assign to each configuration file is unique and meaningful
for each router.
• Before you set up the routing paths, it may be easier to isolate BootP and
TFTP configuration errors on the network if you upgrade all Bay Networks
routers between the BayStack routers and the BootP server to Version 7.80 or
later.
• If you are using EZ-Install over Frame Relay to boot a BayStack router, you
can have up to 20 PVCs for a single Frame Relay interface on the upstream
router. If you have more than 20 PVCs on the Frame Relay interface, the
EZ-Install process may fail. To ensure that the process does not fail, configure
a maximum of 20 PVCs for a Frame Relay interface.
• If the BayStack router or an upstream router will have small routing or
forwarding tables, you can increase performance by reducing the local
memory allocation and allocating more global memory.
• If the BayStack router or an upstream router will have large forwarding tables
(for example, more than 500 servers), you might want to increase the local
memory allocation.
