On the Cisco side, I have things set up as follows: router rip version 2 timers basic 30 30 2 60 300 passive-interface Serial1/0 passive-interface Serial1/1 passive-interface BRI2/0 network 1.2.3.0 network 1.2.4.0 network 1.2.5.0 no auto-summary I cut some networks out, but this basically works for me. You might want to go the the interface that you are ripping over and do a: ip rip receive version 2 Finally, you might want to enable some debugging to see if updates are making their way to the Cisco: term mon debug ip rip events One other little thing. The first time I set this up I was trying to RIP a subnet for which I had a secondary IP address set up on that same interface. It just does not work (which actually makes sense) but I beat my head on it for a couple of days.

Thanks for the pointer! When I did that though, the updates did not seem to be getting through to the router. I'm going to try again because is seems that some changes sort of blow the Cisco's mind for a bit.

(usr-tc) RIPv2 CPU Issue
by G. Douglas Davidson 10 Nov '00

10 Nov '00

I've been using RIPv2 to allow our Cisco to route to our TCs, but I just noticed recently that RIP is a CPU hog on the Cisco. It is consuming around 60 percent of the CPU. Is there anything that can be done to decrease the amount of RIP updates that the TCs send? Is OSPF less of a pig? Should I segement things so that I proxy arp the regular dialups and only RIP a subnet for the people I need to route a subnet to? Any thoughts appreciated. -- ----- G Douglas Davidson | CityNet, Inc. douglas(a)city-net.com | Pittsburgh, PA voice: 412.481.5406 | fax: 412.431.1315 - To unsubscribe to usr-tc, send an email to "majordomo(a)xmission.com" with "unsubscribe usr-tc" in the body of the message.

(usr-tc) Associating IP pools with Modem Groups
by Mike Tindor 06 Nov '00

06 Nov '00

Is there a way to associate IP pools with modem groups? For instance, have an IP pool of 24 for each ADTS-E or an IP pool of 23 for each Prime that we have, and associate that with slot:1 or slot:2 modem group. Is this possible? If so, could somebody provide me with an example to configure it?

(usr-tc) DSP problems
by Steve Cobb 05 Nov '00

05 Nov '00

I've got a TCR with 2 HyperDSPs working fine connected to PRIs. I've had to add another DSP because of expansion. I've got the card in the TCR and have copied the configuration from one DSP to the new DSP, ie trunk settings, swith type, etc. My users are getting unusual high tones at handshake and then the connection drops. I've talked with several 3COM technicians who have said the card is setup correctly. I've had the PRI checked by the telco technician twice and they say that the PRI is good. The 3COM technician had me look at the errors on the span and they were incredibly high for the new card. The telco say that when he hookd his "t-bird" to it (whatever that is) he doesn't get any errors. Anybody have any ideas on how to troubleshoot this? There is a lot of finger-pointing going on.

I'm wondering if there is a way to tell in HyperAccess or by telneting to the rack to see if a user is using mppp. Is there a way to tell if an ISDN user is using two modems?
