PVC status don't go down [7:35389]
Can anyone enlight me on this. I have 2 sites connected through a Frame Relay network as below : Router A Frame Relay Router B My question is this when interface of router A goes down, router B cannot notice it and the whole PVC is not updated as down. But when the interfaces of both routers are configured as subinterface, router B can then update router A's interface as down and the whole PVC goes down. What is concept behind ? Why doesn't the keepalive update both side properly ? Anthony.

Re: PVC status don't go down [7:35389]
The physical interface won't go down until their is a loss of signal from the switch. Is the line protocol up or down on the main interface of router B when router A is down? I look at it like this. Say I have a T1 Frame Relay circuit with 20 64K PVCs mapped to other circuits in a network. If one of the remote routers goes down I sure don't want my T1 to go down. The Subinterface however will show down. This happens in the frame relay network. Once the PVC is built through the frame relay cloud the network knows whether or not either side of the PVC is sending and receiving LMI. If LMI goes away on one end of the PVC, the PVC itself is affected not the connection from the router/CSU to the frame relay switch. Hope this helps!

This would explain why older (or even newer) hardware may support Dot1Q but not ISL.

RE: Ethernet or FastEthernet [7:35245]
Mike, yes the IEEE802.1Q does insert the VLAN tag into the frame (ISL encapsulates the frame.) I am going to try and get this part right. The max frame size for an ethernet frame is 1518, however if you are going to insert the 801.1Q Vlan tag you would require an additional 4 bytes. 2 bytes for Length/Type = 802.1Q Tag Type 2 bytes for Tag Control Information) Bringing the grand total to 1522. I belive that the older chip sets supported a max of 1518 (later the standard was changed to support 1522.) So, I belive that the age on the hardware has a bit to do with this as the change to the frame size (or the IEEE standard change) did not occur until sometime in '98. Now Cisco's ISL came along and decided to take it a bit further. Cisco's implementation encapsulates the frame (the original 1518 byte frame) and by doing so adds 30 more bytes. This 1548 byte max. frame again presents a problem to older Ethernet chip sets. So you may find certine Ethernet HW that will support the 1522 byte size and not the 1548 byte size (I am pretty sure of this but will not swear to it) and hence some hardware will support 802.1Q and not ISL. I hope I am not wrong about this.

Round 1 to the lab [7:35410]
Took the lab Tuesday in San Jose. Missed by a just a couple of points on some really stupid mistakes. The time factor is a killer on this exam. Let me clarify that statement--you have plenty of time to do what is asked of you, the real problem is that you can't hesitate anywhere. You have to be able to read the requirements and decide in a very short period of time how you will satisfy them. For me, this wasn't really a problem accept for one little piece. In my rush to get through the exam in the alloted time, I forgot about the little things. Things I had configured hundreds of times before and were automatic somehow got left right outside the entrance to the room. I ended up finishing the majority of the exam w/ about an hour left and tried to troubleshoot the problems. The automatic things were overlooked because I have never had a problem w/them before. They called time before I could get them resolved and the rest is history. Moral of the story: speed kills in more ways than one. The people out there who have yet to take the exam are probably saying that won't happen to me, that guy just wasn't prepared. Believe me, it will. I was sitting on the other side of that monitor not more than a week ago saying the same thing. I knew how to do everything on the exam, somewhere between my head and fingers it got lost. Round 2 is scheduled for as soon as my 30 days are up. I won't let those same mistakes happen again--believe me, they are etched into my brain. One more command in a certain place probably would have gotten me over the top. You have no idea how bad that burns.

RE: slip/arp/proxy arp switch to csu [7:35413]

Re: Round 1 to the lab [7:35410]
Thanks for the support guys. If nothing else, it has must made me mad and more determined. As soon as I can get some sleep, I'm going to double up my study efforts from before. At this point, just passing is not going to satisfy me--anything less than a 95 is unacceptable. I want to beat it worse than it beat me. This was my first shot. I was convinced before hand that I was ready and I really think I was. I think that maybe I was seduced a little by the aura of it and I let it get the best of me. After experiencing it, the fascination is gone. Now it is sheer determination. Richard--remember it's just an exam. Forget about everything else.

RE: slip/arp/proxy arp switch to csu [7:35413]
well...this isn't really for controlling it like a console connection. This is for snmp traps and NNM polling... If I were to do a reverse telnet to it, that would indeed give me console access but there's no way to spew snmp traps back to NNM serially. I needto be able to assign sl0 an ip address and then give the csu a slip address. A thought beyond my original is that it would have to be from a router and not a switch. because I am goingto have to route to that slip network. so...now...any more comments from anyone else?

I disagree. In order to get a clearance, not only do you have to make the right choices, but all of your past and present friends, roomates, and coworkers need to make the right choices too. Add to that, it only takes one person bad-mouthing you to delay or even end your investigation... ask yourself this, is there at least one person out there who would lie about you in order to make your life difficult? It's a very subjective process, and one that I don't care to go through again. If you have a clearance, be glad that you do.

Re: Lab scenarios - CCBootcamp.com or IPexpert.net [7:35369]
Al, Both labs are really good, you should get them both. IPExpert is a good get-your-feet-wet and intermediate lab package that give lots of indepth insite into the labs that it offers. Ipexpert has good explanation text and makes it easier for beginner/intermediate lab candidates to tackle their labs. CCBootcamp labs are a good followup to the ipexpert labs and are meant for more advanced users because of the level of advanced multi-protocol scenarios. All of the CCBootcamp labs have had the old technologies removed and are now in a 1-day format. You can also do all of the labs without re-cabling if you have the proper equipment setup. thanks, -Brad Ellis CCIE#5796 (RS / Security) Network Learning Inc [EMAIL PROTECTED] used Cisco gear: www.optsys.net CCIE Labs, racks, and classes: http://www.ccbootcamp.com/quicklinks.html Al Walter wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

Well check each end with loopbacks. You can also make a loopback plug with an RJ-45. 12 to 45. I'm assuming that your crossover cable is 12 of each to 45 of the other. 1 - 4 2 - 5 4 - 1 5 - 2 To verify the crossover cable make a loopback jack. (a) Test service module with loopback plug.

Hello everyone... Okay this is the first time I've setup ISDN simulator so bare with me. I basically have TWO cisco routers. A 2503 and a 2522 both of which have a BRI. I also have two Adtran NT1's ACE..on the back of these...there are TWO S/T(Local) ports and to the right of it there is a Network U port. On the side of it there are two LOCAL BUS switches. On one switch it says configuration and switch options are: SHORT and LONG...and the other switch is the Termination: Options are NONE...50100. Im assuming the NT1 setup should be like this, but I'm not sure: On the Teltone Simulator: PORT 1 goes to NETWORK port on Adtran ...and then from Adtran S/T port to the BRI port on the Routerhowever what would be the setup on the adtrans since I get an illuminated ERROR light with the READY light blinking once every second.

At 09:38 AM 2/14/02, Michael Williams wrote: Oleg Oz wrote: The originally ethernet chips used in cisco network modules only supported a fixed frame size. When ISL/802.1Q came along, the hardware needed to support some additional space to accomadate the VLAN info. I could see this as being an explanation. But doesn't Dot1Q fit into a standard ethernet frame? I believe so, whereas ISL adds into to the ethernet frame making it bigger. This would explain why older (or even newer) hardware may support Dot1Q but not ISL. Both ISL and IEEE 802.1Q can confuse older chipsets because the resulting frame can be longer than 1518 bytes. Whether these frames will confuse a chipset or not depends on the age of the chipset, and also on whether the chipset checks the length before it checks the header. ISL encapsulates an Ethernet frame, adding a 26-byte ISL header to the front of the frame, and a 4-byte CRC to the end of the frame. The first 48 bits, which would normally contain an ordinary destination address, contain a 40-bit address, a 4-bit Type, and 4-bit User field used for priority. The first 40 bits are 0x01-00-0C-00-00. A recipient that doesn't understand ISL takes a look at those 40 bits with the next 8 bits and sees a multicast address that it doesn't understand. The recipient should just drop the packet. The exact behavior depends on the chipset, however. A good chip would just say hey, it's not for me, get rid of it. A bad chip would say Yikes this is way too long and report an error, crash perhaps, or do something unpredictable. Now, the IEEE 802.1Q crowd has the advantage that they can influence IEEE specifications. They added four bytes, inserting them where a length/type field would appear normally. They were able to reserve a type field (0x8100) so that all recipients can determine if they should understand the frame or not. The first two bytes of the 802.1Q insertion are actually the Tag Protocol Identifier (TPID). The TPID is set to 0x8100. Because this number is bigger than the maximum size of an Ethernet frame, a recipient knows that the frame is not a standard 802.3 frame and that the field is not an 802.3 length field. If the recipient supports 802.1Q, it continues to process the rest of the insertion as an 802.1Q header. If the recipient does not support 802.1Q, it sees the two TPID bytes as an unsupported EtherType and should drop the frame. On the other hand, a bad chipset might barf. To support IEEE 802.1Q and avoid the need to drop and report baby giants, the IEEE 802.3ac VLAN Tag Task Force received approval in September 1998 for extending the Ethernet maximum frame size to 1522 bytes.

RE: Ethernet or FastEthernet [7:35245]
Great answer. One minor thing. ISL came first. It was designed by Kalpana years ago. Cisco bought Kalpana in the mid-1990s. Priscilla At 10:53 AM 2/14/02, Oleg Oz wrote: Mike, yes the IEEE802.1Q does insert the VLAN tag into the frame (ISL encapsulates the frame.) I am going to try and get this part right. The max frame size for an ethernet frame is 1518, however if you are going to insert the 801.1Q Vlan tag you would require an additional 4 bytes. 2 bytes for Length/Type = 802.1Q Tag Type 2 bytes for Tag Control Information) Bringing the grand total to 1522. I belive that the older chip sets supported a max of 1518 (later the standard was changed to support 1522.) So, I belive that the age on the hardware has a bit to do with this as the change to the frame size (or the IEEE standard change) did not occur until sometime in '98. Now Cisco's ISL came along and decided to take it a bit further. Cisco's implementation encapsulates the frame (the original 1518 byte frame) and by doing so adds 30 more bytes. This 1548 byte max. frame again presents a problem to older Ethernet chip sets. So you may find certine Ethernet HW that will support the 1522 byte size and not the 1548 byte size (I am pretty sure of this but will not swear to it) and hence some hardware will support 802.1Q and not ISL. I hope I am not wrong about this.

Thanks again. Best Regards, Hunt Lee WebCentral Tom Martin wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... Hunt, You are correct, there is nothing filtering the routes entering from Router B, without local preference set higher on 10.1.1.1 (Router A?) for the routes, nothing will prevent AS 202 from being used for other destinations as well. More confusing to me is the configuration. I read the question as if Router B should only be used for packets _originating_ from AS 202, which should use the T1 connection. In this case an outbound filter would be appropriate, along with a community tag of no-export. Even if this the reverse is true (which the configuration seems to indicate), the as-path access-list is only setting local preference for the AS 300 destination! It seems like the following access-list should have been used: ip as-path access-list 1 permit ^202$ Then again, perhaps I have just totally misunderstood the question.

Raj, This one comes straight from RFC 2328. The IP destination address for the packet is selected as follows. On physical point-to-point networks, the IP destination is always set to the address AllSPFRouters. On all other network types (including virtual links), the majority of OSPF packets are sent as unicasts, i.e., sent directly to the other end of the adjacency. In this case, the IP destination is just the Neighbor IP address associated with the other end of the adjacency (see Section 10). The only packets not sent as unicasts are on broadcast networks; on these networks Hello packets are sent to the multicast destination AllSPFRouters, the Designated Router and its Backup send both Link State Update.

Re: VOipVoFR [7:34947]
1. Voice is a low burst rate data in addition to other characteristics required such as low latency, jitter etc. 2. If you really want to think in terms of layers, voice is not layer 4 stuff, it is an application, just as video is. It might go down through presentation layer for say compression before being transported at layer 4 (udp/tcp/rsvp etc) and then encapsulating it into layer 3 packet (IP,IPX etc). 3. VoFR does not necessarily mean that IP is now out of picture and voice is directly being framed into FR. Mostly, IP is still there. FR, ATM, Enet are just media mechanisms. You can skip IP however if you switch a lot. Like frame relay switching or ATM switching etc. 4. DLCI is just locally significant, it is just a way to identify connections.

Re: WAN IP [7:35405]
Brian, Why would this be a problem if you're using two routers that both support a /31 address? There is an RFC (I don't have the number handy) defining this. I can understand the potential if you're not using the same IOS or using routers from different vendors. Ken Brian 02/14/02 07:58PM Begging for problems with non compliant hardware/software??

Re: Re: S.Singh: Faulty Serial Link [7:35379]
Thanks Nadeem, one thing more, when the serial interface goes down, the LED hangs, i.e. even when I remove the serial cable does the LED keep glowing. Only when I restart the router does the LED status come to actual. Can you add to this? I'll tell you the end results of this case, keep checking the mail. Bye.

External MLS-RP for 6500 [7:35472]
Hi All - I have a Catalyst 6500 switch and would like to the MSFC of a different 6500 as the external MLS-RP for the first 6500. How should I include it on the first 6500? There's a command for the 5000, but I couldn't find one on 6500 series. Thanks.

CISCO PIX handling of RST packets [7:35474]

Why is this so? What happens if I send large spoofed packets to the PIX and they get denied. Will the victim client (of the IP address I spoofed) end up getting DoS'ed by large RST packets from the PIX? Thanks in advance.

I can't think of any technical reasons off-hand, but I can think of a possible non-technical one. If Qwest does this sort of thing for many other organisations, giving each organisation a unique prefix may help them to keep track of which networks belong to which organisation - it may make it easier for their techos if they can look at the network address and get an instant reminder of which organisation they are looking at.

Before I even came into this department a few years ago, Qwest !nterprise was helping our company with the network configuration. When they designed the IPX network numbering scheme they began all network numbers with CCC. I recently realized that they're numbering scheme was chosen because it could be easily summarized by NLSP, which we weren't running at the time but I think it was running for a short while. My question is why did they start all network addresses with CCC? I can understand using a scheme that can be summarized but why not simply use 1, 10001, 11000, 11001 instead of CCC1, CCC10001, etc.? Just curious if there is some reason that is eluding me. Thanks! John -- David Madland Sr. Network Engineer CCIE# 2016 Qwest Communications Int. Inc.
