off topic: PIX DHCP (client) Implementation?
Is anyone aware of any 'unique' characteristics regarding the DHCP (client) implementation on PIX 5.x? I tried assigning an IP to the outside interface via dhcp with a linksys switch dhcp server and it failed. When I plugged it straight into my cable modem and repeated the process, it worked just fine. Perhaps the linksys dhcp server component is flawed somehow (even though it works just fine for assigning addresses to other DHCP clients (wintel boxes))?? I replicated the failure three times and also ran debug on the PIX dhcp function with no useful results. (Given the rampant rumors re instability, I already placed knee pads under the chassis, but oddly enough that didn't help.) The only thing I could find online was the following excerpt: Note: Use of the DHCP client feature to acquire an IP address from a generic DHCP server is not supported. (source: http://www.cisco.com/univercd/cc/td/doc/product/iaabu/pix/pix_v53/config/advanced.htm#xtocid57942 ) [So can I assume that my cable company has invested some portion of my huge monthly bills in a "name brand" DHCP server?] Thanks for any info. _ Get your FREE download of MSN Explorer at http://explorer.msn.com _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Re: Stupid question
I'll be quite honest and say I haven't done a detailed investigation of the IOS implementation restrictions here. My intuition would be that IOS has one ARP cache per subnet per physical router, and having multiple router ports in the same broadcast subnet confuses the ARP mechanism. On a first scan of RFC 1812, I don't see any inherent architectural limitation on more than one interface in a subnet on a physical router. I suspect the reason that multiple serial interfaces can work is that they don't routinely ARP, since they don't have to resolve MAC addresses they don't have. However, just in the last few days, we read on this list that serial interfaces can have 2 or more in the same subnet. I think one poster said there was a maximum of 6? Which would be consistent with the maximum interfaces in load sharing. I suspect there are some IOS internal games here, where an (internal only) virtual interface describes the next hop for a destination to which there is load sharing, and some type of recursion takes place (perhaps interacting with a cache) to decide which physical interface to use. These are guesses, however. But ethernet interfaces cannot share a subnet.

Re: Protocols on frame relay switch
The serial ports will 'see' each other, but if you're configuring the hub router as a frame relay switch you are no longer routing IP through the router, you are switching frame relay frames from one interface to the other. In that scenario, an IP routing protocol is unnecessary because you are not doing IP routing. The router is switching frames based on DLCI, so this is a layer-2 function. It is no more concerned with IP addresses than a provider's frame relay switch in a real frame relay cloud. They forward frames based on layer two information only. I know I keep repeating the same concept, but I just woke up and can't form thoughts very well. g HTH, John What does that mean?

Re: Stupid question
This is all new information to me! I had no idea that I could place two separate serial interfaces into the same subnet, so I just tried it. I set up two back to back cables between two routers and put both lines on the same subnet. I was amazed that it didn't freak out. I noticed that when I would ping from one to the other the router did per-packet load balancing regardless of 'ip route-cache' setting, which makes sense. This really doesn't have anything to do with route caching or fast switching. Now I just tried running OSPF across these links and the routers didn't appear to be confused. They each see the other as being adjacent on two different interfaces, but they don't really care. They just put both routes into the routing table. I suppose this is no different than if I were to configure a loopback interface on each side and then use ip unnumbered on both links. In that case they'd also be in the same subnet. Interesting, thanks for pointing this out to me! John I'll be quite honest and say I haven't done a detailed investigation of the IOS implementation restrictions here.

RE: PIX Performance
How's about a little 'real-life' observation on a 515UR/failover package:
Problem:
external limited to ~850Kbit/s since install. Normal range, 2.5-3.5Mbits/s
internal ether on 515 does not exceed 140-160KBytes/s
internal ether has unusual number of IP transport retransmissions.
no apparent loops/collisions/protocol/hardware problems (Fluke OneTouch)
external ether on 515 sends 2.5Mbits/s+ to external IMux'ed T1's fine.
load: well under specs.
no NAT
5.3
internal -- hub/switch -- 100Mb/full -- 515 -- 10BaseT --border router
--T1X3 --external
N.G. Sniffer on internal and external side of 515. Fluke OneTouch as well.
Somehow, it seems that, despite the theoretical, this PIX is throttling the
bandwidth at around 850Kbits/s. The MRTG graph is most unusual and
certainly shows the pattern of a throttle of some sort. Plateau shape, no
spikes. Config normal, as far as a couple of us can tell, certainly nothing
bazaar. I've tried disabling the failover, yes. No NAT *may*, I've heard
speculation, need another kind of treatment. Seems like '0 0 0 0' with
statics wouldn't kill the throughput...
How or why it's down that has been a baffler for a couple of days/nights.
Maybe it's broke.
If anyone might have a suggestion on what to look for ('show what?)|(debug
what?) I'd listen. Otherwise, handy syslog indicates the thing is doing
it's job. A "must have" device.
However, to keep internal peace, I may have to not have until I can get a
solution.

IDS monitoring Port Mirroring/SPAN
OK, here's the deal, I need to monitor a T-3 before and after a Firewall So:ISP---7206Switch-FirewallSwitchRouterLANs with the 2 different IDSes ( Intrusion Detection System ) hanging off of a monitor port on each switch. I was starting to get collisions on the firewall and the router with a 100Mb hub so, I figured if I wack 2 Cisco 2912XL switches in there and set everything for 100Mb Full, and that would end that issue and it has, but has raised another one. So far, at the switch points, the switches are running at 80% according to the LEDs on the front, with our current bandwidth at about ~20Mb. What are the LEDs measuring is my first question? If it is the CPU utilization, I have a feeling it is because of Span/port monitor that the CPU has to duplicate the packets and ship them out the monitor port. My 2nd question is: If this link goes up to the max 40+ Mb, will I start dropping packets between the router(s) and the Firewall? Will I drop packets going to the IDSes? We have a Cat 5000 sitting around so, I figured, why not just use it? I tried to enable two different Port spans on a Cat 5000 and it will only allow me to do one at a time. I figured a Cat 5000 would have enough CPU power to do the job. I was going to create 3 VLANs, one VLAN before the firewall and one after and one for management. But if I can only do (1) span at a time, this isn't going to work either. Suggestions? Or am I worrying for nothing? Will the 2912's do it or do I need to go the 3500XL or 4000 series switches to do this? What is everyone else doing?

do NOT Teraterm Pro, it doesn't work. The reason is that I think Cisco user SSH version 1.5.x or something which is something Teraterm does not support. Try putty.

Re: Stupid question
The limit on Cisco routers is 4 Serials in the same subnet... but my question is: What problem does that solve? Why would I want/need to do that? Any thoughts? Z From: "Howard C. Berkowitz" [EMAIL PROTECTED] Reply-To: "Howard C. Berkowitz" [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: Re: Stupid question Date: Sat, 31 Mar 2001 10:29:36 -0500 I'll be quite honest and say I haven't done a detailed investigation of the IOS implementation restrictions here. My intuition would be that IOS has one ARP cache per subnet per physical router, and having multiple router ports in the same broadcast subnet confuses the ARP mechanism. On a first scan of RFC 1812, I don't see any inherent architectural limitation on more than one interface in a subnet on a physical router. I suspect the reason that multiple serial interfaces can work is that they don't routinely ARP, since they don't have to resolve MAC addresses they don't have. However, just in the last few days, we read on this list that serial interfaces can have 2 or more in the same subnet. I think one poster said there was a maximum of 6? Which would be consistent with the maximum interfaces in load sharing. I suspect there are some IOS internal games here, where an (internal only) virtual interface describes the next hop for a destination to which there is load sharing, and some type of recursion takes place (perhaps interacting with a cache) to decide which physical interface to use. These are guesses, however. But ethernet interfaces cannot share a subnet.

If you are routing, each interface on the router must be in its own subnet. Otherwise routing would not work. If you're bridging, then the bridged interfaces are in the same subnet but you don't specifically assign an IP address to those interfaces. I'm guessing that you're really asking the former question: in a routing situation can two different interfaces be in the same subnet, and the answer is no. _ Get your FREE download of MSN Explorer at http://explorer.msn.com _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Re: OSPF over FR - stop me before my head starts bleeding
Below you'll find the FR switch configuration (important parts, anyway). Also, s0.2 on R3 is a point-to-point PVC to another router (R6). In the last hour, I've actually gotten the OSPF to work correctly by using "ip ospf priority" statements. What was happening was that R4 (a spoke) was always taking on the role of DR, and since R5 couldn't talk to R4, it wasn't receiving any O routes. I've now made it so that R3 is always the DR. I think a DR is necessary because it's a multipoint network - similar to an ethernet network in an addressing sense. However, I still have a problem - R5 can't ping R4. I've added map statements to no avail. R5 knows all the routes, but either it's not sending packets out its S0 interface, or R3 isn't routing them on R5's behalf.

Route filtering - reprise
Dear Group, A while ago I brought a problem to the group re: two networks on the same wire, (prime and secondary on the router e0 interface) and using policy routing so that one went out one serial and the other went out the second serial. Neither LAN should go out the other's serial (or come in). Also the routes should be advertised such that the core should not send traffic down the wrong pipe. All sorts of things were tried but got messed up due to the secondary address. Finally, using 2 ospf processes and 2 eigrp processes got the "job" done. A total of 4 routing processes. However, that didn't sit right and I have being trying to do it in BGP. I have a config that works. It was done on a 2611 router with 6 ethernet (instead of serial). Here are the relevent parts. interface Ethernet0/0 description Uplink to LabR05 ip address 198.103.224.2 255.255.255.252 ! interface Ethernet0/1 description Uplink to LabR06 ip address 198.103.224.6 255.255.255.252 ! interface Ethernet1/0 description Client LAN ip address 142.226.20.1 255.255.255.0 secondary ip address 142.226.10.1 255.255.255.0 ip policy route-map client ! router bgp 65300 network 142.226.10.0 mask 255.255.255.0 network 142.226.20.0 mask 255.255.255.0 neighbor 198.103.224.1 remote-as 65500 neighbor 198.103.224.1 timers 5 10 neighbor 198.103.224.1 route-map R5out out neighbor 198.103.224.5 remote-as 65500 neighbor 198.103.224.5 timers 5 10 neighbor 198.103.224.5 route-map R6out out ! ip local policy route-map client ip classless ip route 0.0.0.0 0.0.0.0 198.103.224.1 ip route 0.0.0.0 0.0.0.0 198.103.224.5 no ip http server ! ! ip access-list extended client1 permit ip 142.226.10.0 0.0.0.255 any ip access-list extended client2 permit ip 142.226.20.0 0.0.0.255 any route-map R5out permit 10 match ip address client1 set ip next-hop 198.103.224.1 ! route-map R6out permit 10 match ip address client2 set ip next-hop 198.103.224.5 ! route-map client permit 10 match ip address client1 set interface Ethernet0/0 ! route-map client permit 20 match ip address client2 set interface Ethernet0/1 * This works great. HOWEVER. Always one of these I have uncovered a "quirk" or bug that I can't find on CCO. Getting ready to open a Tac case on this one. If the router is reloaded, after it's up and just before the "Press return to get started!" line - I see this: "Secondary addresses not allowed with negotiated addresses" Processor board ID JAB024801KB (751772336) M860 processor: part number 0, mask 49 Bridging software.

I can put it back in and the router does not complain. Save the config and everything is happy again! (until the next reload) Does anyone have a handle on that one??

Re: Stupid question
The limit on Cisco routers is 4 Serials in the same subnet... but my question is: What problem does that solve? Why would I want/need to do that? My gut tells me that this is not really a planned-for limit, and sort of happened. Any thoughts? As a wild guess, it might be to allow the support of NBMA hub-and-spoke subnets that have more than one hub interface. Not sure how useful this would be -- I tend to think that the marginal improvement in reliability of having more than one interface of the same router in the same subnet is very small. If I need multiple hubs, multiple routers become appropriate. _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Re: IDS monitoring Port Mirroring/SPAN
I am using a 2900XL with 2 IDS's and Internet monitoring software on it. There are three vlans on it. It is working great. If you need more info email me offline. Neil ""Scott Nelson"" [EMAIL PROTECTED] wrote in message 9a580l$a2n$[EMAIL PROTECTED]">news:9a580l$a2n$[EMAIL PROTECTED]... OK, here's the deal, I need to monitor a T-3 before and after a Firewall So:ISP---7206Switch-FirewallSwitchRouterLANs with the 2 different IDSes ( Intrusion Detection System ) hanging off of a monitor port on each switch. I was starting to get collisions on the firewall and the router with a 100Mb hub so, I figured if I wack 2 Cisco 2912XL switches in there and set everything for 100Mb Full, and that would end that issue and it has, but has raised another one. So far, at the switch points, the switches are running at 80% according to the LEDs on the front, with our current bandwidth at about ~20Mb. What are the LEDs measuring is my first question? If it is the CPU utilization, I have a feeling it is because of Span/port monitor that the CPU has to duplicate the packets and ship them out the monitor port. My 2nd question is: If this link goes up to the max 40+ Mb, will I start dropping packets between the router(s) and the Firewall? Will I drop packets going to the IDSes? We have a Cat 5000 sitting around so, I figured, why not just use it? I tried to enable two different Port spans on a Cat 5000 and it will only allow me to do one at a time. I figured a Cat 5000 would have enough CPU power to do the job. I was going to create 3 VLANs, one VLAN before the firewall and one after and one for management. But if I can only do (1) span at a time, this isn't going to work either. Suggestions? Or am I worrying for nothing? Will the 2912's do it or do I need to go the 3500XL or 4000 series switches to do this? What is everyone else doing?

When I had an 8MB flash in slot0 and a 4MB in slot1 the show flash thinks it's 16MB. That's what confused me. And when I put the 4MB in slot0 it registered correctly.
