bgp path selection criteria
hi , Anyone here knows which BGP path criteria takes precedence ? AS_PATH or local preference From what I read it is local preference , but in actual fact it is not so , why I said this is because I have a customer who prepends their prefixes many times then advertise them to us but on our side we set local preference to customers' routes to 90 which in fact will always come back to us if we do this but this is not happening Instead the prefixes go to another providers' link because their AS-PATH is shorter why is that so?

thank you very much your explanation is crystal clear -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of [EMAIL PROTECTED] Sent: Tuesday, October 10, 2000 1:50 PM To: [EMAIL PROTECTED] Subject: RE: keepalive set in frame-relay circuit? 10 seconds is the default, and should generally be fine. Your circuit is probably down for some other reason. Is this a test setup, with the routers connected back-to back (or with another cisco as a switch), or is the frame relay circuit a 'real' circuit from a telco? Assuming it's a real circuit, try the 'show frame lmi' command. Your 'num status enq. sent' and 'num status msgs recv' values should be the same (or very similar), and non-zero. If they aren't the same, clear the counters, wait a minute or so, and check again. If you are not receiving any LMI messages, then you're not talking to the frame relay switch. This is not a good thing. Either your router config is wrong (wrong encapsulation? wrong lmi type? could be a few things) or the telco service is broken (or dud hardware, potentially). If the LMI looks OK, try the command 'show frame pvc', or turn on term mon and do a 'debug frame lmi' (it's a fairly safe debug to do even in a production environment, unless your routers are very overloaded or you have zillions of PVCs. But I take no responsibility if it breaks your network :-). See what PVCs are defined, and which ones the telco knows about. See if they match what you think they should be. With the debug frame lmi command, you will see (hopefully) LMI messages coming from the switch. Check that they're coming in every ten seconds. If not, change your keepalive to match. Every now and again (every minute on mine, YMMV) the LMI message will include the status of all the PVCs the switch knows about, and their status (I believe the exact format of the messages varies between frame switch types. On mine, an active PVC has status 0x2, and an inactive one has status 0x0). Even if you force the interface up/up by fiddling with the keepalives, it won't pass any data if the circuit's broken.

RE: what is mean reverse telnet ?
The term reverse Telnet means that you are initiating a Telnet session out the asynchronous line, instead of accepting a connection into the line (which is a forward connection). To establish a reverse Telnet session to a modem, determine the IP address of your LAN (Ethernet) interface, then enter a Telnet command to port 2000 + n on the access server, where n is the line number to which the modem is connected. For example, to connect to the modem attached to line 1, enter the following command from an EXEC session on the access server: router# telnet 172.16.1.10 2001 Trying 172.16.1.10, 2001 ...

weird bgp flapping problems!!
hi anyone knows why when my link goes down for 2 mins and up again BGP is still flapping and regains its full functionality only after several hours , by right it should come up by itself quite fast after the serial came up right .

This is because my bgp is fully functionally receiving all the routes only after a few hours after my serial went down and up again for 2 minutes Not a good idea. Every time you do it, the rest of the net sees a route flap from you. Too many flaps over a period of time, and others will "damp" your advertisements, ignoring them for what can be rather lengthy periods of time. If you see the session flapping due to serial line issues on one link, why would you want to clear the entire BGP routing table? This will just cause problems with your other sessions. If you're having line problems with one of your BGP peers that is causing the session to flap, it's a good idea to admin down the BGP session with that neighbor until the problem is fixed and the line is stable. In router config mode: (config-router)# neighbor www.xxx.yyy.zzz shutdown To restore once the line is fixed, (config-router)# no neighbor www.xxx.yyy.zzz shutdown This will allow your other BGP sessions to continue unaffected. Then call telco or whatever you need to do to isolate the serial line problem without causing route flap and trying to push customer data over a flaky line. Turn the session up once you've fixed the line problem. If the line is flaky enough so as not to keep a stable TCP 179 connection, it isn't going to be much good for much else, so shut it down and get it fixed. "clear ip bgp *" will flap all sessions on that router, making things quite unstable for a period, especially if you're a transit provider or have IBGP sessions going as well, as they'll flap and spike CPU on your other internal routers. If you're single homed over a single link, consider a static default instead of BGP. Your router and your upstream will be much happier. -- Jay Hennigan - Network Administration - [EMAIL PROTECTED] NetLojix Communications, Inc.

bgp flapping due to serial down for a while but administratively shut down bgp wont work??
hi all, I have tried administratively shut down BGP when my serial link goes down for a while but it didn't work Administratively shutting down the BGP won't help much in this case. It can only prevent the Serial flapping to not affect the BGP. But after the Serial is stable, then I turn the BGP up again then the BGP will start flapping. Because there was once I move my router to another UPS which means I have to shut down the router, after the serial is up and stable the BGP still flapping. It was outside the sun outage window and the serial was stable before and after I move my router but the BGP is flapping. There was once also I tried to temporarily not advertising any routes to you to prevent my network get dampened. The serial is stable but the BGP is flapping. This is almost the same with shutting down the BGP like you advised. But this way I can see whether my BGP is flapping or not without risking my network to be dampened. With the BGP shutted down I cannot see whether the BGP is stable or not. Jason **NOTE: New CCNA/CCDA List has been formed.

RE: ospf bandwidth question
CRC errors could be due to modem clocking rate not configured properly etc. FECNs are generated when data is sent out a congested interface; they indicate to a DTE that congestion was encountered. Traffic is marked with BECN if the queue for the opposite direction is deep enough to trigger FECNs at the current time. BECNs notify the sender to decrease the transmission rate. If the traffic is one-way only (such as multicast traffic), there is no reverse traffic with BECNs to notify the sender to slow down. Thus, when a DTE receives an FECN, it first determines if it is sending any data in return. If it is sending return data, this data will get marked with a BECN on its way to the other DTE. However, if the DTE is not sending any data, the DTE can send a Q.922 TEST RESPONSE message with the BECN bit set. Whenever you have BECNS or FECNS it could be that a powerful link is sending data down a not so powerful link , e.g. a T1 link sending data down a 56 K link and when packets reaches the 56 K side the link may not be able to take it and hence the BECNS bit is set You may want to implement adaptive traffic-shaping based on BECNS Jason -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Stull, Cory Sent: Thursday, September 28, 2000 11:24 PM To: '[EMAIL PROTECTED]' Subject: ospf bandwidth question If I am getting many CRC errors and FECNs and BECNs on the frame-relay network what would be a cause of that?

Thanks. -- From: Spolidoro, Guilherme [SMTP:[EMAIL PROTECTED]] Sent: Monday, September 25, 2000 9:15 PM To: '[EMAIL PROTECTED]' Subject: RE: RADB - BGP routing You can find a lot of information about RADB on the RADB.net web site. The problem is that I never found some examples or explanations on how large ISPs use the information stored on the IRRd servers on real life. Maybe somebody with more experience could comment about that. Anyway, RADB runs an IRRd server that is used to store each ISP routing policy, for example: what are your AS numbers, your networks, what networks you'll accept from ISP xxx or what networks you're going to advertise to ISP (just two simple examples). You write your policy using a specific language (like an script) that can be used to configure the BGP on your NAP/MAE routers. There are serveral IRRd servers and RADB.net host the "official" one for the US. RIPE has another server for Europe and some ISPs have their own server. I'm not sure why an ISP would want to have his own IRRd server, but my guess is that they probably use that information to know what are their customers's BGP policies for them, i.e. what networks their customers will advertise for them so they can configure the BGP filters properly. I know of at least one ISP that won't accept any advertisement from their customers unless register on the RADB IRRd server. It's my opinion that since everybody can use the information on the IRRd servers as they want, it's always good to keep it up to date so you don't have somebody blocking your networks because you didn't register your latest policy there.

In other words these messages (BECNs) are intended to make users aware of a possible degraded network state. Its a warning (from the Telco) saying if you're over utilizing your link, back off because we're gonna have to start dropping frames if this congestion doesn't subside.

If you type in ip unnumbered ethernet 0 it means that the interface that you type in this command has ip address that takes the value from ethernet 0 You often do this where you have a lot of async interfaces for dialing in but you only want to worry about a single ip address for all these async interfaces for routing purposes Jason -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of rsma Sent: Friday, September 22, 2000 2:12 PM To: [EMAIL PROTECTED] Subject: what is unmumbered? **NOTE: New CCNA/CCDA List has been formed.

At the opposite end things will appear OK as the router has the LMI activated at that end. Use show fr map to see if dlci 659 has mapped to a different IP address. Remember that the dlci number only has local significance, they do not have to match at both ends. I agree with Omar that it is likely that the pvc's are misconfigured if you are active on one end and not the other. Get the service provider to confirm that LMI is activated, if your interface does not go up and up, get them to put a loopback to you, and sh int to see if it loops. If it does not, it is likely that they have not cabled the opposite end of your line in the exchange. Once the interface goes up and up, the LMI stat recvd will increment with the LMI enq sent. This will confirm that the router is talking to the switch. Then you can use sh fr pvc to see which pvcs have been built, and sh fr map to see what they can see at the opposite end.

If the router receives any BECNs during the current time interval, it decreases the transmit rate by 25%. The rate will continue to drop with each BECN (limit one drop per time interval) until the traffic rate gets to the minimum acceptable incoming or outgoing committed information rate (MINCIR), where it stops. Once the traffic rate has decreased, it takes 16 time intervals of receiving no BECNs to start to increase traffic again. Traffic increases (Be+Bc)/16, or more accurately, the byte limit that shows up in show traffic and show frame-relay pvc x divided by 16. Thus, it takes much longer to get back to committed information rate (CIR) than it did to drop to the MINCIR (similar to slow start in TCP/IP). One way of making this length of time much shorter would be to set "Be" 7 times the value of "Bc," which would ensure it gets back to CIR immediately after going through 16 time intervals without a BECN. Also of note is that this increase only occurs when traffic shaping is active. If traffic shaping is not active, the transmit increment stays the same even though BECNs are not being received. --Original Message-- From: "Yee, Jason" [EMAIL PROTECTED] To: "cisco@groupstudy. com (E-mail)" [EMAIL PROTECTED] Sent: September 18, 2000 7:15:52 AM GMT Subject: what does becn and fecn high value indicate? hi , Anyone Knows what the BECN and FECN in sh frame-relay pvc indicates : and a high BECN indicates what?

Of course you cannot control the FECN and BECN bits. What you can do though is adjust the manner in which your IP traffic negotiates moving from fast links to slower links (LAN to WAN etc). This is where the bandwidth command amongst others can be useful. For example, routing off a fast ethernet port across the router into one of its serial ports requires a slowing of traffic. Serial ports cannot handle anywhere near 100mb of traffic. There are a number of ways one can handle this; prioritizing, queueing and using the bandwidth parameter are a few that spring to mind.

RE: what does becn and fecn high value indicate?
thanks your explanation is crystal clear Jason -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of [EMAIL PROTECTED] Sent: Tuesday, September 19, 2000 11:22 AM To: [EMAIL PROTECTED] Subject: RE: what does becn and fecn high value indicate? Basically, BECNs and FECNs indicate that the frame relay network is congested somewhere along your PVC. You're getting a lot of 'in BECN packets' but no 'in FECN packets', which means that the congestion is affecting traffic going from this end of the PVC to the other end. The congestion may or may not be caused by your traffic. If you have frame relay traffic shaping turned on, then if your router receives BECNs, it will throttle back the outgoing traffic on that PVC. When the BECNs go away again, it will gradually increase the traffic rate. Have a look at the router at the OTHER end of your PVC if you can (same command). You will probably see a lot of 'in FECN packets'. If you also have a lot of 'in DE packets', then you are at risk of getting a lot of packets dropped - Discard Eligible packets will be dropped in preference to non-DE packets. If you send a lot of traffic at a rate above your CIR, you might want to increase your CIR. It won't directly help the congestion, but it will mean less of your traffic is marked DE (so it's less likely to be dropped), and also many carriers provision their networks on the basis of purchased CIR - so it might prompt your carrier to upgrade.

If the router receives any BECNs during the current time interval, it decreases the transmit rate by 25%. The rate will continue to drop with each BECN (limit one drop per time interval) until the traffic rate gets to the minimum acceptable incoming or outgoing committed information rate (MINCIR), where it stops. Once the traffic rate has decreased, it takes 16 time intervals of receiving no BECNs to start to increase traffic again. Traffic increases (Be+Bc)/16, or more accurately, the byte limit that shows up in show traffic and show frame-relay pvc x divided by 16. Thus, it takes much longer to get back to committed information rate (CIR) than it did to drop to the MINCIR (similar to slow start in TCP/IP). One way of making this length of time much shorter would be to set "Be" 7 times the value of "Bc," which would ensure it gets back to CIR immediately after going through 16 time intervals without a BECN.

RE: Clocking Question
I think it can be summarised as such if the modem is providing clocking to the router then modem is the DCE device router is the DTE device whereas as in the case of the lab scenario where we do not have a modem then we need to join two routers together to simulate a WAN link then for the virtual WAN link to work one of the routers need to provide the clocking . The router which provides the clocking is the DCE device while the router which receives the clocking is the DTE device . To find which router is the one suppose to provide the clocking do a sh controllers s0 or s1 to check which is running DCE or DTE hope this helps Jason -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Rajagopal Iyengar Sent: Tuesday, September 19, 2000 11:58 AM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subject: Clocking Question Hello Group, My Name is Rajgopal and I am based in Bombay,India.I have a question for you guys. I have read in the CCNA 2.0 Exam Certification guide by Wendell Odom that a DTE is the equipment that receives the Clocking information from a DCE which is the device that sends the clocking information for sync Links and at the same time he also says that a serial line comming from the ISP is connected to a CSU/DSU which in turn is connected to your serial port in the router and the CSU/DSU is the device which gives the clocking information for the sync links. Whereas the ICRC book says that by default the Cisco router is a DTE equipment and the minute we implement the clocking command on a particular serial interface then it becomes a DCE device. Correct me if I am wrong but for the clocking command to work on the enterprise side we have to enable the clocking command.Then does that interface become a DCE ??And if it becomes a DCE then doesn't it defy the rule that a DTE is connected to a DCE ?? The ICRC book also says that in case if you don't have a CSU/DSU u have to use a back to back cable to connect the 2 routers and the interface on which u implement the clocking command becomes a DCE interface.But don't u think that its the ISP which gives u the clocking information?? Please enlighten me on this subject as soon as possible because I have my CCNA exam on the 21st of Sept,2000 and I would like to be clear on as many concepts as possible.

RE: line protocol down
hi all , With regard to my problem.I was troubleshooting this morning and the problem is still with their receive. I first disabled LMI and had him do the same on his router along with no keepalives. The PVC came back up from the perspective of the frame relay switch (with LMI enabled it was down). I send 100 packets to him, he doesn't receive them on the router PVC stats. I show the packets traversing our frame relay network with zero discards or errors. He sends me 100 packets, I show 100 packets coming into our network. any comments Jason -Original Message- From: Erick B. [mailto:[EMAIL PROTECTED]] Sent: Wednesday, September 13, 2000 2:47 PM To: Yee, Jason; cisco@groupstudy. com (E-mail) Subject: Re: line protocol down Hi, First of all, your serial interface has input errors and CRC errors. You have sent LMI but haven't received any LMI probably due to these input errors and CRC's. I would check the circuit and CSU config. Once you get the line issues sorted out, heres how to troubleshoot frame based on the output you gave. Your DLCI 659 is DELETED which is assigned to your sub interface. Note, it was active when the interface was first brought up for a short time. This is normal on Cisco routers. The DLCIs are marked as active when interface is first brought up until LMI is received or not. Do a 'show frame pvc' and see what DLCIs your learning from the provider's frame switch if you are. Your LMI type is ANSI, is this correct? You can do a 'debug frame lmi' to see LMI packets. LMI is the management protocol where your DLCIs are learned, status of them, etc. It has to match that of switch. In the debug output, you will get at least 2-3 lines for each LMI poll (plus one more for each PVC, DLCI). The PVC/DLCI lines in 'debug frame lmi' begin with PVC ... and in middle will have dlci ##. If you don't see PVC lines in debug output your not learning any DLCIs and theres a issue w/the configuration of the providers switch/frame mapping to you, LMI mis-match, or a line problem. You can switch the LMI-type see if anything changes as well (while your waiting for provider to callback). If debug frame lmi looks good, then do a 'show frame map' to see what inverse-arp is picking for remote address's since your not staticly mapping them with a frame map statement. What does 'show frame lmi' show for input/output (bottom 2 lines of output).

The company I work for has Frame-Relay over Sattelite to Europe. The Ping times are ~ 950 ms+ It costs ~$20,000 a month. If you are talking about the home internet service that works over sattelite, and uses one of the 19" dishes that are popular for Digital Television, then you should know they are one way links. You have to request the data over a Dial-up/lease-line, and it comes dwon from the sattelit to you. From the one person I know that has it, It seems to be too much trouble, the latency is too high, and the Bandwith is aroun 192Kbps.

It's probably not worth it unless a significant part of your traffic is with hosts located just behind the remote satellite hop or with a high-bandwidth path to the satellite hop.

RE: HDLC, SDLC...
I can explain the first three protocols namely hdlc, sdlc, lapb First of all they are all WAN protocols, which is layer 2 protocol for communicating across a WAN link, which protocol to use depends on two factors the WAN technology that you use and the communicating equipment HDLC stands for High-level Data link Control which is the default encapsulation type on point-to-point , dedicated links. It is used typically when communicating bet two CISCO devices. It is a bit oriented synchronous data link layer protocol.HDLC specifies a data encapsulation method on synchronous serial links using frame characters and checksums. If communicating with a non-Cisco device , synchronous PPP is a more viable option SDLC stands for Serial Data Link Control use mainly for SNA networks and lapb Link Access Procedure, Balanced is for X.25 links Jason -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of perez claude-vincent Sent: Wednesday, September 06, 2000 1:46 PM To: [EMAIL PROTECTED] Subject: HDLC, SDLC...

Apparently , this is not a very easy exam with nearly 30% on BGP stuff so know your BGP stuff well , also like what the rest in the list has just mentioned there are no fill in the blanks cisco ios commands questions but they do have choices of over 90 to let you choose so know your command well especially the mode that you are supposed to execute those commands. The rest of the questions focus on the other routing protocols like EIGRP, OSPF know them well especially the LSA types in OSPF and the types of areas , types of routers etc. So I am off to take my next paper BCRAN , any tips and pointers for this exam will be greatly appreciated thanks once again Jason ___ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED] ___ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
