Hi, We are using a standard setup which matches a QoS policy-map against Class-Maps using an ACL for certain types of traffic. We then DSCP mark this traffic on Egress and use WRED and CBWFQ. for example: access-list 101 permit tcp any any eq 3200 access-list 101 permit tcp any any eq 3600...

Is there a general feeling about the relative latencies and performance between site to site connectivity using a site to site VPN or using a Cisco VPN Client and a 3000 concentrator? Would the Client method be an accurate way to simulate the latency that we would expect to see if we configured...

Yes, One of the bigger sites has 8x6500, there is HSRP on the VLAN interfaces, just a mix and match of layer2 and 3 in a sub-optimal configuration. There are loads of routes in the IP routing table (maybe 300) as the site uses BGP distributed into OSPF from their MPLS WAN. Most LAN routes show...

I've actually got many many LANs that i see this in as i'm working on a network refresh on a global company. I am thinking about say 2x 6500's with up to 10 VLANs, all of which have an OSPF adjacency across them. Is this a bad thing, or just a waste of resources and extra work for the switch...

What is the best practice for controlling adjacencies between multilayer switches with multiple VLANs. I have a LAN to explore that has several 6500's, none of them using Passive-interface so the Show IP OSPF Neighbors shows many adjacencies. Is this a problem, or something that is best...

altenatively try this: GNS3 can't remember the URL so google it.

All good advice from people here. I started in IT a long time ago with a CCNA and then spent many years mainly working with MS servers and very little Cisco work. i then stalled in my career and got tired of servers and desktops and end users. I studied very hard for about 9 months and got a...

All good advice. I do intend to keep going with the studies to CCIE, so the CCIP seems a very good use of my time as the subjects seem to feature largely in the CCIE. I've been reading the Odom book, it's a good read. Previously i was doing BGP and reading that book became tortuous really...

I have heard that LAN QOS has largely been taken out of the syllabus, is this the case?

I'm ramping up to do the QoS exam at the end of this month. I was studying BGP then got sidetracked by work/life so started the CCIP again on QoS.(it's much easier i reckon) I'm reading the Wendell Odom Book cover to cover. Has anyone else done the QoS? What's it like? any other good resources?

I've had the same problem. I just can't seem to find the time to sit and study. BGP is a pretty dry subject though. Real hard work to stick with. I've booked the BGP exam for 27th March though to give me a kick up the backside to do some study. It looks real hard though..... It makes OSPF look...

I can't supply a config as it was one of 2000 routers, and i'm not sure which one anymore. It's been changed by now anyway. not a lot of use i know....

No protocol was being used, it was static routing and a DDR ACL to bring up the ISDN. the ACL encompassed traffic from the Lo0 source address, so it later emerged that the traffic repsonsible was a 255.255.255.255 boradcasst from the Lo0 address. Weird....

I've had a stange one. An ISDN line kept coming up hundreds of times, tests showed that the interesting traffic was from the loopback address to 255.255.255.255 Adding a deny line to the ACL stopped this happening, but why oh why should a loopback address broadcast anything? No services were...

I would also agree that buying some real Cisco kit is a good investment as ultimately you're trying to get familiarity with the actual routers and switches that you're going to expect somebody to pay you a lot of money to be competent working with. Also Dynamips is worth a look.....

The best one i heard was for the OSI model: All Prostitutes Seem To Need Deep Penetration That made the class laugh.

That sounds good. I've heard that Qos is the easy one and i've already read that book (only once, 9 months ago, so it's far from learnt yet) so i thought diving into the hard ones first might be a good idea. I've basically not touched BGP since the BSCI exam and it's all fallen out the side of...

Hi Everyone, I finished my CCNP over a year ago and i've been feeling the need to move a step closer to the magical holy grail of CCIE. I've just begun CCIP study as I reckon these topics are totally necessary to master before CCIE. Does anyone have a link or any hints to where I could get the...

I've just passed the Pix exam and it wasn't too hard. I had done the course though and spent a lot of time at work recently doing PIX stuff which certainly helped. It was a bit of a sidetrack from what i wanted to be doing: CCIP as i have already got a CCNP and i reckon that the CCIP stuff is...

Thanks Eurobadger. I reckon you're right. (The xx.xx.xx.xx was just the next hop IP address, i didn't want to have to write the full 207.211. etc etc) cheers
