Re: Can I picks a PIX?
Dear "Cthulu, CCIE Candidate"" a) Correct me if I'm wrong: You can not make "conventional" router's to pick up DHCP address on the interface, though you can do this with DSL routers and latest flavours of IOS for this routers b) If it was possible - how are you going to configure interfaces if you erased nvram? In all ciscos I saw if you erase config and then reload a router, it comes up with all interfaces shutted down - so they can not pick up anything from the network. much better option is to save the config you want at start up in the flash as init.conf for example and copy it in to start-up and reload router every time you want go to the initial step. it is shame, they do not ask such things on the CCIE written, isn't it? :-)) _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: Solaris on Intel platform
Lilian, I think you can find better advices in groups dedicated to SUN products. This group is dedicated to Cisco rather than SUN Anyway, Can't help you with Solaris 8, but I used Solaris 2.6 on several Intel machines, it works pretty fine and I liekd the prformance, but hardware was (and I suspect still is) an isuue- do not worry that much about video because you can replace native Solaris Xserver with xfree86 - jsit read all related release documents. Did not have ANY single problem with CPU or motherboard, but better use motherboard from the manufacturer listed in Hardware compatability list.

Re: Wild Card Mask Puzzle - fun in the sun
x.x.x.1 0.0.0.230 answer would be correct for the PIX firewall (they use reverse wildcard mask - match 1, do_not_care 0) but in router case should not this be x.x.x.1 0.0.0.24? if we put this in binary: (forget about first three bytes ) 8 7 6 5 4 3 2 1 1 - 0 0 0 0 0 0 0 1 9 - 0 0 0 0 1 0 0 1 17 - 0 0 0 1 0 0 0 1 25 - 0 0 0 1 1 0 0 1 it gives us the following - we want 1 in the position 1. 0's in 8,7,6,3,2 and do_not_care in 5 and 4. For the access- lists on Cisco routers 0 is match, 1 is do_not_care so wildcard mask should be 0 0 0 1 1 0 0 0 which gives us 24 x.x.x.1 0.0.0.24 sutisfies this condition RGRDS, Evgeny -- *** Please DO NOT send replyes just directly to me, post them to the Newsgroup as well *** ""Nigel Taylor"" <[EMAIL PROTECTED]> wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Well, in light of everyone jumping in there I taught I might do the same. > Here what fell out of this simple mind. > > access-list xx permit x.x.x.1 0.0.0.230 - ask me how I got this? > > Man, I was thinking now I'm all screwed up...

Re: Static Routing or Route Maps
Cormac, You are absolutely correct (but Bal [EMAIL PROTECTED] was the first to point this out) Unfortunately I was wrong saying that HSRP can not track link failures (will read documentation more thourouglly:-),(and I 100 % agree with you that to run some kind of routing protocol to your ISP(BGP for example) is a better idea than to use statics, though it may involve series of talks with ISP guys. Routing protocol can help to eliminate the other issue with links (if they are FrameRelay) - if pvc fails somewhere inside FR cloud you local switch may not report failure - so for the HSRP link will look like functional. Roting protocol will eventually (recieving no updates/hellos etc) remove route from the routing table.

Re: file can't be deleted on 3640
When you just issue "delete file" command -IOS does not actually delete file - it marks file as deleted and hides its name (see example below - deleted file test_file_to_delete) , so you can undelete it later, These hidden files can consume quite a lot of memory if you do not watch for them. The other problem that if you copy another file into the flash, it is being written AFTER last byte of the "deleted" file, so you end up having "black holes" in your flash. The only way (at least the only way I know about with 5300 and 3600) to get rid of them is to "erase flash". you can see your hidden files with "dir /all" cwas-access#dir Directory of flash:/ 1 -rw- 7575284c5300-is-mz.121-1a.T1.bin 2 -rw- 392241mica-modem-pw.2.7.1.0.bin 16777216 bytes total (8799356 bytes free) cwas-access#dir /all Directory of flash:/ 1 -rw- 7575284c5300-is-mz.121-1a.T1.bin 2 -rw- 392241mica-modem-pw.2.7.1.0.bin 3 -rw- 10137[test_file_to_delete] 16777216 bytes total (8799356 bytes free) RGRDS, Evgeny ""Palis Michael"" <[EMAIL PROTECTED]> wrote in message 00e901bfe4de$3e65e100$[EMAIL PROTECTED]">news:00e901bfe4de$3e65e100$[EMAIL PROTECTED]... > I tried it on my AS5300 and it works > > I issued the command delete flash: and the file was deleted > without any problem > > > - Original Message - > From: Evgeny Babanin <[EMAIL PROTECTED]> > Newsgroups: groupstudy.cisco > To: <[EMAIL PROTECTED]> > Sent: Monday, July 03, 2000 1:48 PM > Subject: Re: file can't be deleted on 3640 > > > > I had the same problem (btw 5300 is the same)- You have to erase flash > > before copying new file. > > > > RGRDS, > > Evgeny > > "Jim Bond" <[EMAIL PROTECTED]> wrote in message > > [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > > > Hello, > > > > > > I copied IOS file to flash memory but got checksum > > > error.

Re: Static Routing or Route Maps
The only problem with HSRP is that it can not detect link failure,as its purpose is to create router hardware redundancy. Plus, if routers are not on the same Ethernet segment HSRP will not work. So the configuration can look like that: a) routers are on the same Ethernet segment HSRP + floating static routes(or any IGP between two routers - RIP for example) HSRP Ip address is the default gateway for the internal routers/workstations Every router has statically defined default pointing to the ISP and other default with greater AD pointing to the neighbor REAL (Not HSRP) address. In this case if the router itself fails - HSRP will take care of the traffic, if link fails - router will insert floating static route in to the routeing table an forward traffic to another router. b) routers are in different locations - No HSRP, so no hardware redundancy only floating static routes. RGRDS, Evgeny ""Michael L. Williams"" <[EMAIL PROTECTED]> wrote in message 8joa3u$mgm$[EMAIL PROTECTED]">news:8joa3u$mgm$[EMAIL PROTECTED]... It seems to me using HSRP would be the best thing to do. That way, not only do the two routers act as redundant links for each other, they can load balance across them. Mike W.

Re: Layer 3 switching vs. Layer 4 switching?
Francis, The process you have described looks more like "load-balancing"/"load-sharing" - Cisco LocalDirector supports that kind of traffic management. It seems that Layer4 switches do a bit difeerent thing (though mosty of them do load-balancing). We use FoundryNetworks Layer 4 switches in some of our implementatios for redirecting traffic to the WebFilter/cach engine. The switch is able to redirect packets on per-tcp-port basis. For example we have configured ours to redirect all http requests to the WebCache engines and let everything else through RGRDS, Evgeny ""Arigo, Francis"" <[EMAIL PROTECTED]> wrote in message 304545310AD0D3118F9900600897AD9A07743B@GALILEO">news:304545310AD0D3118F9900600897AD9A07743B@GALILEO... > We use an Alteon Web Switch that uses "layer 4 switching".

Re: How far by self study?
I passed my CCNP and CCDP mostly on self-study (I attended only CID course) in 5 weeks ( exam every Saturday ). As far as I saw it is relatively easy to pass exams if you go to the courses - all you need is to read training materials carefully - ALL exam questions ARE in these materials.
