I have 4 PM2-E's, three with 30 analog modems, the last has 10 modems and
one ISDN-U BRI card, all active.
The PM's are all in one large subnet of a class C on an ethernet switch,
along with a few Unix hosts- telnet-service users talk to the Unix hosts fine.
I'd like all my PPP users to have addresses out of a different C network,
only used for them (makes filters easy). Some users are on ISDN and have
each a 16-address subnet from there, the rest of the PPP (analog and ISDN) users
each have a single address assigned.
None of the Unixes run 'routed', so I believed Livingston's documentation where
it says I can give them and my router a static route to one PM, and that one
will forward packets to the appropriate PM.
The ISDN PM has lots of RAM and handles all the ISDN users with their small
subnets (as above, analog PPP users get a single, assigned IP address), so
I put a static route on the Cisco and the Unix hosts saying that PM is
the gateway to the PPP class-C.
It doesn't work.
Looking at debugging on the Cisco and the ISDN-PM, sometimes the other
portmasters are announcing default routes to the whole class-C, and
other times they don't seem to send announcements at all. What gives?
Do I need to turn off RIP on the Portmaster and let default routes take over?
Could it be related to the version of ComOS?
The PM's ship with 'set default off', I left that setting alone, but
I do have 'set ether0 routing on' for all the PMs.
