LLQ Modular QoS on VPN/Tunnel/or POS [7:69792]
All, I'd try this myself if I had a router at my fingertips... 1. I'd like to apply LLQ for my VoIP traffic over a site to site VPN using Cisco's Modular QoS technique. Will the router "bark" if I try to apply my output service policy to the tunnel interface? Or do I need to apply it to the regular serial interface? 2. Also, in a different network, can I apply my output service policy to a POS interface, or will the router bark? I've applied service policies to serial interfaces in the past with no problem, but you never know what will happen when it's a new kind of interface. - Jennifer Mellone Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=69792&t=69792 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

RE: 4006 IP Phone DHCP problem [7:56049]
Larry, I noticed you have the command "switchport trunk encapsulation dot1q". Do you need to configure the interface/port as a trunk when you do the "set port auxiliaryvlan" command (catos) or the "switch voice vlan" command (ios switch)? According to Cisco's website, you don't for a catos switch, but you do for an ios switch: Check this out: http://www.cisco.com/univercd/cc/td/doc/product/voice/ip_tele/network/dgcampus.htm#xtocid364019 NO TRUNKING HERE ON CATOS SWITCH: Voice VLAN Configuration To configure the VVID from the Catalyst software CLI, use the set port auxiliaryvlan command. You can use this command to set the VVID on a single port, on a range of ports, or for an entire module. The following example shows how to display the command syntax: Console> (enable) set port auxiliaryvlan help Usage: set port auxiliaryvlan (vlan + 1..1000) In the following example, the VVID is set to 222 for ports 2/1 through 2/3.

RE: MPLS and QOS study materials for R&S Written [7:56099]
I was thinking of using the appropriate sections of the QoS Configuration Guide and Multiservice Configuration Guide (IOS 12.1) from the Cisco CD/Web. I figure they need to be read for the lab anyway (that's why I picked IOS 12.1). I started reading the QoS guide, and it has theory in the beginning and config stuff/examples later on. I like it because it's structured/organized (vs. reading a URL here and a URL there). But is it enough detail (and the right info.) for the test? Is this a good idea?

RE: frame-relay traffic shaping [7:55432]
Here's a sample section of a map-class config that I wrote up for VoIP FRTS,
complete with running commentary on the commands (including min CIR and
CIR). Scott Keagy's Integrating Voice and Data Networks (Cisco Press) was
great for frame relay traffic shaping.
map-class frame-relay theframeclass
{Do not use the command frame-relay fragment , as this is recommended to
reduce serialization delay for speeds of 768K or less.}
frame-relay mincir out 1536 {This is the provisioned CIR assigned by
service provider}
frame-relay cir out 1536 {Technically, this is higher than min CIR, since
traffic can be sustained at a higher rate thats CIR. But make CIR=Minimum
CIR here.}
frame-relay be out 0 {Set excess burst to 0 since we dont want to burst
over CIR for voice.}
frame-relay bc out 15360 {Set committed burst, which is 15360 bits, or
1/100 of CIR (1536K CIR). This makes serialization delay=10ms, a reasonable
value. Serialization Delay = frame size (bits) / link bandwidth (bps).}
no frame-relay adaptive-shaping {Turn off because we do not want the frame
relay circuit to throttle back. If the router receives BECNs on the
interface, the router would start to throttle back to the Min CIR value.
This is why we turn it off and lock the Min CIR to the actual CIR value.}
service-policy output thepolicy {attach policy here for the queuing. If you
dont put a policy here, frame relay traffic shaping defaults to FIFO. In
that case, you would override with the preferred frame-relay fair-queue.}

Study CCO URLs vs. Cisco Press for CCIE Written? [7:53767]
Hi CCIE Written Candidates, Have you looked at the URLs on the Cisco blueprint page? These URLs are kind of ad-hoc, and some use IOS 12.1 and some use IOS 12.2. Ad-hoc drives me crazy since I desire structure. So I have an idea for a study procedure - let me know what you think: Simply go to the appropriate configuration guides (versus command reference) on the Cisco website (documentation CD) and go through the sections that match up with the blueprint. I figure that 12.1 is best, since that's what's in the lab. For example, the QoS Configuration Guide at would do nicely for the QoS section of the test. Of course, if there's a chapter of a config. guide in there that isn't on the blueprint, just don't read that chapter. My logic? I figure that we'd have to read the "CD" anyway to prepare for the lab...We'd get a leg up on it. Everyone keeps saying "the CD is your friend". If I don't understand something, I can always consult the Cisco Press books for another point of view on a subject. Also, a single chapter in a config. guide contains theory at the beginning, with practical config. commands in the middle, and verification/troubleshooting at the end, with the "show" or "debug" commands. Now that the test has changed to a more scenario/practical format with "show" and "debug" output, perhaps that's a good thing? The downside is hunting through and picking out the applicable chapters, then finding a nice fast printer (hopefully duplex) to use at night when nobody is around ;-) What does everyone think about this idea? It's certainly a radical departure from my CCNP prep, where I used the Cisco Press course books and used Doyle/Halabi/Caslow etc. to clarify some specific things. And what about Caslow? I thought that book was mainly for lab prep. But maybe now that the test has changed to a more scenario/practical format, it's good to use it for the written? And I have the first edition... - Jennifer PS- I actually haven't tried any of this yet. Got to get organized first so I can do this in a methodical and structured manner.

Wanted-CCIE Lessons Learned/Attitude/Plan [7:49167]
LESSONS LEARNED, ATTITUDE, AND STRUCTURED STUDY PLAN I was wondering if anyone could elaborate on "lessons learned" when studying for CCIE. What did you do right? What did you do wrong? If you had to do it all over again, what would you change - especially if someone wants to pass the first time? I think the attitude "do it right and try and pass the first time" could be helpful (I know it doesn't always happen in reality). It seems more positive than "I'll fail the first time so I know what to expect the second or third or later time". My instinct tells me that determination and practicing on the routers every night and on weekends for at least 6 months is key, and is easier said than done. There are no short-cuts. This is fine; it's the price one must pay. But how does one do that in a methodical and structured manner such that all the major stones are unturned? Of course, some stones will be unturned quicker than others due to experience, and others will be slower due to lack of experience/knowledge. I feel "ad hoc" practice could be counter productive. For example, a structured approach would be something like: go through Caslow's book and do the labs for x-months, and/or do the Fat Kids for x-months, and/or do the CCBootcamp labs for x-months, and take the Caslow course x-months before the lab, then hammer down on the weaknesses, etc. Some comments on this would be great. I realize this is like Navy Seal training. No amount of conditioning will *fully* prepare you for the famous "hell week". As the Seal trainees say, "The Only Easy Day Was Yesterday" ;-) - Jennifer Mellone CCNP, FNCNE (Foundry Networks) B.S.E.E., M.S.

Networks vs. Aggregates for Multihoming
ISP A asked me which 2 ARIN class C's I wanted to advertise. I told them
xxx.yyy.216.0 and xxx.yyy.217.0. Then they came back and said, did you want
us to announce the 2 /24's or the /23?
I thought, isn't this up to me? I'm the one who configures it on my end.
For example, I can use the aggregate command if I want to advertise the /23,
and I can leave out the aggregate command if I want to advertise the 2
/24's.
router bgp zzz
network xxx.yyy.216.0 {advertise the Class C address to the Internet}
network xxx.yyy.217.0 {advertise the Class C address to the Internet}
!
aggregate-address xxx.216.0.0 255.255.254.0 summary-only {send the summary
route/aggregate route vs. individual routes}
I figure it's best to use the aggregate command to keep the ISP/Internet
routing tables down. Is this good strategy to use the above config when I
do the multihoming/backup/load share thing (have another router configured
exactly the same way, but to ISP B?

Also 6.1 may require more memory or flash, which you may or may not have. 5.5.4b was in vogue before the holidays (fixed some bugs in 5.5.4). But now 5.5.5 is available on CCO.

Sanity Check: Setting up 2-Cat6509s (each with 2 MSFCs) with FlexWan modules: BGP, 2 ISPs
Can you tell me if this (see diagram below) can be implemented, and will it work right for BGP load balancing, redundancy, etc.? It's 2xCatalyst6509s, each with 2 MSFCs (supervisor with router built in), and each with 1 flexwan module (like a 7500 port adapter, with a serial interface for T1). Each 6509 connects to a pix. The pixes are configured for failover. Since the pix can only have one default route, I figure I need HSRP. Configure static route on MSFC with pix as next hop. But the traffic will only go through the top catalyst as a result (bottom catalyst is the backup). Note that there is 1 unique IP address per interface per MSFC card (see diagram). Someone said I needed that. I thought the 2 MSFCs in 1 box could have the same IP on the interface; that same person said no. Vlan 100 is the external vlan. Vlan 50 connects the 2 "routers" together, for the IBGP. I'm a bit squirrely on this vlan 50 thing with the IBGP. Is that ok? Do I need the vlan 50, or should I remove it and have the IBGP go through Vlan 100? That same person said I can get rid of vlan 50.

Section Analysis: Routing Principles (not so many questions) Extending IP Addresses (not so many questions) Configuring OSPF in a Single Area (tons of questions) Interconnecting Multiple OSPF Areas (alot of questions) Configuring EIGRP (not so many questions) Configuring Basic Border Gateway Protocol (tons of questions) Implementing BGP in Scalable Networks (not so many questions) Optimizing Routing Update Operation (a few questions) Implementing Scalability Features in Your Internetwork (a few questions) Types of Questions: 1) Theory, and lots of it, where you have to pick the best 2 or 3 of the bunch 2) Here's the config, and what does it mean, what does it do 3) Which config. accomplishes the following xxx 4) What command do you use to do xxx, and you select from a huge list in the exhibit; know if you're in global mode, interface mode, etc. 5) Drag & drop "matching" style 6) Summarization related 7) Apply the theory you know to some situation, such as interpreting show command outputs Key Concepts to Study (theory and implementation): Distance Vector/Link State, How BGP/OSPF/EIGRP work (e.g., updates, hellos, opens), ip helpers, OSPF LSAs, Summarizing, BGP route selection criteria, route reflector, next hop, prefix list, policy routing, redistribution (for BGP/OSPF/EIGRP), basic show commands Resources: 1. If you have the BSCN course material, that's great. Or buy Cisco Press BSCN book when it comes out. These are bread and butter for the test and keep you focused on what you need to know for the test, rather than having to dig around multiple sources (I hate that). 2. Supplemental resources to further explain things that you don't fully understand from the above are Doyle's TCP/IP Cisco Press book, ACRC Cisco Press book, Halabi's Internet Routing Architectures Cisco Press book, and Thomas's OSPF Cisco Press book (to view the show command screen outputs). I basically used these for reference, not for reading cover to cover. Practice Tests (do after you think you're done studying for the test): 1. Boson (I bought test 3, which has some lu lu's on there, especially quiz D. Each of 4 quizzes in test 3 had 51 questions, so test 3 had 204 total questions. Some questions stressed the same stuff over and over, but that's ok so I can retain and take each quiz just once. Test 1, 2, or 3 can be downloaded for about $30 each from http://www.boson.com/) 2. Free CCO/Colt (strange wording that will deflate your confidence if you use that as a basis for your understanding, plus they don't give you the answers; they just tell you which questions you answered wrong) http://www.cisco.com/cgi-bin/front.x/wwtraining/colt/ColtLogin.pl Misc. Tips: There is no such thing as too much studying! The questions really make you think and apply what you learned; very few questions are simply recalling things by rote (those of course, are the easy ones). Close the books by 10pm the night before the test and watch ER :-) I'll post to the list as I continue the road to CCNP. Jennifer L.

BSCN: Distribute lists and prefix lists- extended or standard?
Please tell me if I am correct: Distribute lists are defined by standard access lists (vs. extended access lists). True? Prefix lists are also defined by standard access lists. True? - Jennifer _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
BSCN: BGP Atomic Aggregate
Does anyone know an easy definition of what the atomic aggregate is and what it does?

BSCN: Seed/Default Metrics with Redistribution
When you redistribute into a protocol, which metric do you use? The books say use a metric consistent with that of the receiving protocol. The books say, for example, use 20 when the receiving protocol is OSPF, which is default. What metrics should you use for the other protocols? Would you use the same metric every time (like 20 for OSPF)? Here are the commands: For redistribution into OSPF or EIGRP redistribute [] [metric ] ---now for eigrp, what metric do you put there, as there are 5 metrics (see below) For redistribution into EIGRP or IGRP default-metric For redistribution into OSPF, RIP, or BGP default-metric - Jennifer _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Maximum Number of Route Maps Applied to a Neighbor?
How many route map statements can I apply to an EBGP neighbor? Is it only 1 inbound and 1 outbound?

Traffic "threshold" for BGP?
Here is our BGP setup with a single ISP: external 7507 router (EBGP, AS yyy)) || | 4 T1's | 1 DS3 || ISP router#1 ISP router#2 (AS xxx) (AS xxx) Here's what's happening: All inbound/outbound traffic is going through the DS3, and no traffic is going through the T1s! Here's what the manager wants: Load balancing with the DS3 and T1s (T1's not a backup mechanism). He wants all 5 circuits to be used all the time. He wants the T1's to be used first, for example, and when the load reaches 50% on them (or any other %), the DS3 gets used. Kind of like dialer-load threshold with ISDN ;-) I'm not aware of anything like that, are you? He specifically wanted me to ask that question... But I was thinking that the only way you could do load sharing is have the T1's be preferred outbound (higher local-pref than DS3) and the DS3 inbound (lower MED than T1). Currently on the router the route-maps set both local-pref and MED inbound/outbound on all circuits! Not very clean. - Jennifer Mellone, BGP rookie ___ 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]
FRS 2.0 Book Ideas (applies to all 3 2.0 tests)
Hello FRS'ers, How are the following Cisco Press books http://www2.ciscopress.com/series.cfm?series=2&news=0 for FRS 2.0 (or each individual test for that matter): Route: "Advanced Cisco Router Configuration" (skip the appletalk and IPX), but supplemented with BGP from Basam Halabi's nice BGP tutorial on Cisco's web site http://www.cisco.com/warp/public/459/bgp-toc.html. The tutorial is less overwhelming than the full "Internet Routing Architectures" book; book can be used to fill in some more details on topics. Dial: "Building Cisco Remote Access Networks" (tailored to dial 2.0 vs. 1.0?). Switch: "Building Cisco Multilayer Switched Networks" (CCNP series) vs. "Cisco LAN Switching" (CCIE series). The CCIE series book is a great professional reference to have around the office when doing real world stuff, but kind of big to read cover to cover (for a test) vs. BCMSN book. - Jennifer ___ 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]
BGP - 1 DS3, 4 backup T1s, 1 ISP
Hello folks that are also "Geeking Out" over the 4th of July---
We are revamping the Internet architecture, and we are going to have a brand
new external 7507 with 1 new DS3 and 4 T1s. There will be EBGP and static
routing. Right now the T1s are on the existing external router with static
routes and OSPF. The internal router (and it's replacement 7507) has/will
have static routes and EIGRP. EIGRP is the main protocol in the netork.
Anyway, the 4 T1s will backup the DS3, but when the backup occurs, I'd like
them to load share. I read that ebgp-multihop is the technique to use when
load sharing parallel links, using the loopbacks vs. the regular neighbor
addresses.
a. Can you tell me if my proposed BGP config is correct or point out things
that are wrong or missing? Config. is below.
b. Is this backup strategy good?
c. The T1s won't be used unless the DS3 dies, right?
d. Do I need to worry about filters or attributes (like weights, local
preference, MED, etc.) in this case?
e. Oh, should I do ip route-cache or no ip route-cache on the T1s and DS3?
I figure leave the defaults ip route-cache to save on CPU cycles.
f. I want this config. to be a stepping stone in case the we decide to
connect to another ISP. Would another external router be required?
