Implementation Notes
Nortel Networks recommends that you first install an AN/ANH or ARN
router in the same site as your BootP server, Site Manager workstation, and
other Nortel 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 AN/ANH
or ARN 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 Nortel Networks
routers between the AN/ANH or ARN routers and the BootP server to Version
7.80 or later.
If you are using EZ-Install over Frame Relay to boot an AN/ANH or ARN
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 AN/ANH or ARN 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 AN/ANH or ARN 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.
