Hi Group,
I've tested a config of 100k static routers on a 3845 router, and a
dynamips 3600 too:
I've created a 100k file of static routes with a perl script, thanks to
Leigh Harrison:
http://www.groupstudy.com/archives/ccielab/200510/msg01594.html
I've created some interface parameters around the static-routers and
saved the file on a TFTP server. The configuration of the (emulated)
router containted a configuration statement to load the configuration
from TFTP. The configuration with 100k static routes is about 4 MB, no
problem since the configuration is loaded from TFTP to
running-configuration,
After the configuration is loaded via TFTP, you'll have to wait for
about an hour before the prompt returns :-)
After that you can do funny things with you 100k static route table.
I've created 10 BGP peers, to load a core router up to 1 million routes
in the BGP table,
Have fun,
Regards,
Henk

Onderwerp: Re: How many static route allow on each router
You are in fact limited by NVRAM. A co-worker wanted to simulate the
routes in the entire BGP table in a Juniper lab and I helped them out by
scripting the conversion to static routes (yes....I know alot of good
data is lost in transaltion but that wasn't the point). In the end the
router wouldn't write the config to NVRAM even after enabling service
config compression....it was simply way too much. If it matters we were
using a 7206/NPE-G1.
Been over a year now so I have no idea what the limit was.
