MPLS on 2500 - the final chapter [7:56375]
This weekend I've had a chance to spend some more time with the experimental IOS version that supports MPLS for 2500's, and have been sucessful loading it on five routers. I've done quite a few MPLS configurations from various books, and it seems to work great. I haven't seen any flacky behavior from the routers at all. I updated the instructions on www.laganiere.net to include a text capture of the process of loading it, and a basic configuration. I hope some people find it useful...

Re: Tag-switching and MPLS interface commands [7:56368]
1- Pre-standard implementation of MPLS on IOS platforms was called tag switching. All configuration, debugging, and monitoring commands used to configure MPLS on IOS therefore used the tag-switching keyword 2- tag-switching ip appears in the configuration even when you type mpls ip . This is for backward compatability with older IOS versions incase you needed to downgrade the version for any reason. 3- tag-switching default is TDP, while MPLS is LDP ( you can change this if u want ). 4- tag-switching is Cisco propriarity while MPLS is the IETF standard. Other than that commands can be used interchangable.

Re: ack attack or config prob? [7:56341]
Hi Garrett, There are two DOS attacks that I know of that use ACKS called stream.c and raped.c, the stream.c sends ACK packets to the target with random sequence numbers and source IP's. The raped.c sends ACKs with spoofed source IP's but I believe the sequence numbers are the same.

I don't think you can set the parameters that badly!? :-) It sounds like a DoS attack because of the volume of 100,000 packets. What's the timeframe, though? You said burst so I assume pretty quick. Did the problem happen just once or has it reoccured? What do any relevant logs show? Do you have a firewall or Intrusion Detection System that logs info? How about the server itself? Does it show anything in its log? Were all the packets to the server? Were they ACKs or SYN ACKs? You mentioned both. Were they in response to something your server sent? Were they always the same ACK number? What were the port numbers? You mentioned e-mail, so were the packets to port 25 for SMTP? SMTP implementations used to have many security flaws. Hopefully those would be fixed in a modern OS, but you never know. Usually, DoS attacks are SYNs, but there are probably ones that use ACKs or SYN ACKs too. A search on Google might reveal more info. Anyway, I think you did the right thing by getting the ISP security folks involved.

When you have to make simple facts difficult, ambiguity is the best way! I took my CCNP exams just before the switch, and the only way I could see to make them more difficult would be to make the questions more ambiguous.

Re: Pix non-Rfc networks. [7:56347]
To answer the question asked by Gaz, the router will always send the packet to the route with the most specific mask specified. So, in your example, it will go to the default gateway because the route you added has the most specific mask possible (/32). Gaz wrote in message news:200210262249.WAA18680;groupstudy.com...

If your internal network is using one subnet, your devices will never be able to get to devices on the Internet using addresses from the same subnet. When your machine looks at the destination address, it thinks it is on its local network (layer 2) and will not even bother going to the default gateway for it. I've done the same thing by 'fat fingering' the mask to encapsulate more than the intended addresses (255.255.0.0 instead of 255.255.255.0 for instance). If the destination address would normally fall outside your subnet, but you stuffed up the mask and now it is included, your machine doesn't bother going to the default gateway to find it. Can I chip in with a question for everyone now? If you apply more specific routes to all devices for an address which should appear on your local subnet, will it then try the routed path to the device. eg Machine addressed 100.100.100.100 255.255.255.0 route add 100.100.100.10 mask 255.255.255.255 [default gateway] Not that you'd want to do it, but just wondering.

I'm fairly positive a PC will do a logical AND of the destination IP, come up with a network address, compare that against it's own network address, deduce that the IP must be local and send a layer two broadcast for the MAC associated with the IP -- therefore said host will not need to consult a routing table... source NAT on incoming addresses, use an ALIAS type function (I believe version 6.2 code supports destination NAT) to assign the web servers ect on the outside network (with same IP range as inside) another address range as they come in...

My question is what is the advantage of assigning (2) IP addresses to the same NIC card. If we do that with (2)NIC cards, then it is understandable that you are making your Server Multihomed/Router, but what is the advantage of assigning (2) ip addresses to the same card besides in Web Servers to run multiple websites through Server.

Same thing as secondary ip address on a router. Let's say you have 2 ip subnets within the same LAN. All you are doing is creating an IP presence on an IP subnet.

RE: run VoIP on a frame network at BIR instead of [7:55833]
John, Yes, and No. We still run IPX over our network (don't ask). JMcL John Brandis wrote: Hi Jenny, Is your carrier Telstra ? Do you use Telstra TPIPS for your cloud/next hop router ?

I asked our telco about this as well (quite a while ago), and they said that on entry to the cloud, they automatically reset any DE bits set. So either way, your scheme isn't likely to work, but how much of a negative effect it has will depend on whether your telco drops entering DE packets or just resets the DE bits. JMcL Steven A. Ridder wrote: This was Cisco's old theory. In theory, it would work, but in reality, if the frame switch saw a packet come into it's ingress interface with the packet already marked DE, it will drop it because it was unexpected. I asked the telco's your question last year and that's the answer they gave me. Cisco seems to have abandoned that theory a while ago, which is probably why you haven't seen it written anywhere. dj wrote in message news:200210171534.PAA26762;groupstudy.com... Running a VoIP application over a frame-relay network with 256k CIR and 512k BIR. From the LLQ docs I reviewed, to guarantee good voice quality, traffic shaping all frame traffic to CIR is recommended along with LLQ of voice packets. Would like to take advantage of BIR bandwidth and still guarantee voice packets are not dropped by the frame relay switch network when congestion occurs. Here are my thoughts: What if the router were to pre-mark all data packets as Discard Eligible (DE) on the outbound serial interface connected to the frame network. Voice packets would NOT be marked DE. Then run up to BIR rates with LLQ prioritization for voice. Would the carrier frame network switches drop only the pre-marked DE data packets (by the router) when congestion occurred and NOT drop any voice packets? I haven't found any Cisco links that addressed QOS in this fashion. Any links on this topic would be greatly appreciated. The objective is to squeeze more bandwidth (BIR vs CIR) out of your frame relay network without dropping any voice packets. Why would this not work and what are the caveats? regards, dj ** visit http://www.solution6.com UK Customers - http://www.solution6.co.uk * This email message (and attachments) may contain information that is confidential to Solution 6.

Trying to work out what answer/statement is least wrong, is what I do all day whilst listening to my tech support staff. Its amazing but you get what you pay for.

Excellent work... Congratulations!!! --- Dennis - Original Message - From: Juan Blanco To: Sent: Sunday, October 27, 2002 4:12 PM Subject: Thanks God... [7:56389] Team, This morning I was able to pass the DQoS test, wow...what a rideThe test is very hard if you don't have the Course Book and the reason is because all the information need for the test is very well put and organized by the course. All the information required for the test is on Cisco's web but is very hard to find it, the test follow the blueprint by the book. I want to give my special thanks to Chuck Larrieu (The Long and Winding Road) for his support. I really recommend this test for those who are in the process of taking the lab. The following link will take you where you can find all the information need for this test except the Course Book (fully recommended). Well now to get back to the books for the CVOICE (another animal) test. A good starting point for the QoS on CCO is the following: DQoS 9E0-601 Cisco AVVID QoS Guide http://www.cisco.com/univercd/cc/td/doc/product/voice/ip_tele/avvidqos/index .htm Cisco IOS QoS Solutions Guide 12.2 http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/fqos _c/ http://www.cisco.com/warp/public/788/voice-qos/voip-ov-fr-qos.html ... http://www.cisco.com/univercd/cc/td/doc/cisintwk/intsolns/qossol/qosvoip.htm http://www.cisco.com/warp/customer/788/voip/delay-details.html.
