(usr-tc) arcs and ospf
by Mike Andrews 26 May '00

26 May '00

I've been having a really bizarre problem off and on the last week or two. Occasionally some of my ARCs will suddenly stop doing OSPF right. The routing table loses all OSPF routes, and the ARC stops announcing its routes via OSPF to our Ciscos. Disabling/enabling OSPF doesn't help, but most of the time (not all the time) rebooting the ARC will. One thing that seemed to trigger it was rebooting some of our Ciscos... and since that happens so infrequently (not rebooted since going to ARC 4.2 in fact) it's hard to track down. I don't know which one exactly, maybe our AS border router dying is what threw it off. It also happened last night when I installed a Cisco Catalyst 2924XL (replacing an old 10BaseT hub, finally!) which didn't involve rebooting the Ciscos, but involved having them unreachable for a minute or two as cables were switched and Spanning Tree did its thing... I have another ARC with no modems on the same LAN (for testing) and it initially did the same thing, but now I'm having trouble reproducing it. When it was screwed up one night, it fixed itself overnight, but it obviously took hours to do, which kinda defeats the purpose of OSPF. I know this is really vague, but problem is, I don't really know where to start looking for this, because I didn't document very well what my current OSPF settings are. (A bulk-config-to-ASCII utility would be REALLY HELPFUL HERE :) I could reverse-engineer HARM and try to get a dump of that part of the config via SNMP somehow, I guess, but... yuck. Anyway, I'm also not a real in-depth OSPF guru yet. Has anyone seen anything like this before or know of any particular settings that I might want to check? This is driving me nuts (not to mention my customers) and I'm not sure where to start.

(usr-tc) more netserver questions
by Brian 23 Mar '00

23 Mar '00

If you have a netserver net0 configured as say: 12.1.2.1 255.255.255.0 and in net0 routing is set for "broadcast"......is it going to try and broadcast 12.1.2.1 as the default for 12.1.2.0? The routing table shows something like: Destination Gateway Flag Met Interface VPN -------------------- ---------------- ---- --- --------- --- 12.1.2.0 /24 12.1.2.55 NLC 1 net0 0 so would it try to announce that via RIP if "broadcast" was enabled under net0? ----------------------------------------------------- Brian Feeny (BF304) signal(a)shreve.net 318-222-2638 x 109 http://www.shreve.net/~signal Network Administrator ShreveNet Inc.

(usr-tc) Hiper TCs and Memory...
by Stephen Amadei 01 Mar '00

01 Mar '00

Hi guys, I was wondering if adding memory to my Hiper TCs would help performance. Is there a guide to how much memory is needed for X number of DSP cards? I am up to 8 DSPs in one of my chassis, and I'm wondering if the standard amount of RAM is hurting performance. Thanx in advance. I am running the latest TCS 3.6 code and IP only. ----Steve Stephen Amadei Dandy.NET CTO Atlantic City, NJ - 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) CIDR and Netservers
by Brian 29 Feb '00

29 Feb '00

A few netserver questions...........with regards to classless routing. Is their any gotchas on a netserver when dealing with classless routing? configuring net0 seems ok, since it asks for netmask. But configuring pools, if you just do: set assigned 12.1.1.1 set size 62 How is it going to announce that (in rip)? As a /8 network :) (which is the classfull address for a 12.x.x.x network. I know the commands exist: set enh_routing on add ippool dialup1 12.1.1.1 62 add netmask 12.1.1.0 255.255.255.192 is that whats suppose to "fix" its classfullness and make it announce classfull.............? and finally :) how do you display these "ippools" on the netserver once set? Forgive me, its been almost 2 years since I've worked with netservers but I am trying to help someone out.

(usr-tc) Netserver / ARP
by Brian 29 Feb '00

29 Feb '00

Has anyone ever heard of a netserver spoiling the ARP cache of a Cisco (don't ask me how, it just happens). Like imagine a lan, with a cisco router, and a netserver on that lan. You traceroute like www.yahoo.com, and it goes to the cisco, and then to the netserver! "sh ip route" on the cisco shows it should take "default", show ip redirects is empty, show arp looks normal............yet........"clear arp" fixes the problem! proxyarp disabled on the netserver........this is on 3.8.1.......... ----------------------------------------------------- Brian Feeny (BF304) signal(a)shreve.net 318-222-2638 x 109 http://www.shreve.net/~signal Network Administrator ShreveNet Inc.
