RE: Serial0 is up, line protocol is down!
There can be a lot of reasons for the "Line protocol down" 1. The cable connected from the router may be Bad. 2. The CU is not sending the clock. Check whether all the pins such as DCD, DSR, DTR,RTS,CTS are UP. 3. There should be same config for Keepalive at both the ends. Either no keepalive or keepalive set 4.

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. RGRDS, Evgeny - Original Message - From: "Cormac Long" [EMAIL PROTECTED] To: "Evgeny Babanin" [EMAIL PROTECTED]; [EMAIL PROTECTED] Sent: Monday, July 03, 2000 6:10 PM Subject: Re: Static Routing or Route Maps There are a couple of issues to clarify here: 1. If the 2 routers are not on the same LAN, HSRP is irrelevant (as has been pointed out below). 2. If on the same LAN HSRP can work well because it IS capable of detecting WAN link failure (you can configure it to "track" the WAN interfaces). You can also use the preempt feature to ensure that the preferable link will always get used if it is available. 3. Are these static routes being redistributed into a dynamic routing protocol? If they are then you configure the redistribution metric to bias one over the other. 4. In any case running a dynamic routing protocol to an ISP is usually not a good idea (security, plus co-ordination with the ISP). Regards, Cormac Long CCSI#21600 http://www.cormaclong.com --- Evgeny Babanin [EMAIL PROTECTED] wrote: 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.

Re: Solution - Encapsulation problems Cisco/Motorola - Frame Relay
Ooh, that's a good one! From your original post we were all assuming that the Cisco and Motorola gear were directly connected, as the case would have to be for our "fixes" to work. In your case, things are different: the encapsulation is not end-to-end, but only from the Cisco to the cloud, and from the Motorola to the cloud. CDP runs at the datalink layer in SNAP frames, IIRC, which the Motorola gear doesn't like. To top it off, not only is CDP in SNAP frames, but it's cisco-specific. No wonder the Motorola stuff didn't like it! Thanks for yet another good troubleshooting quiz! John Neiberger Hi there My colleague has solved the problem and I though to let you guys gals know.

I teach BCMSN and it is quite different to CLSC. It is far less focussed on hardware and there is no ATM or FDDI. Additional stuff you do need to know includes: 1. RSM configuration on the Cat 5500 2. HSRP 3. There tends to be quite a lot on VTP 4. IP Multicasting (IGMP, CGMP, Spase and Dense mode routing on the RSMs).

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]...

Re: FastEtherchannel using Compaq Servers
You do not need trunking on the ports to get them to work together... it's a channel you need to configure. Since your subject includes FastEtherChannel, I presume you already knew this? But you do not mention it in your message? Sometimes there is a confusion between trunking and channeling. The first one is to transport traffic of multiple VLANs over one link. The later one is to group several physical links together into a logical link with a greater capacity. Do you have a channel configured which includes the two ports connected to the Compaq?

Re: connecting different Autonomous Systems?
Hi, I am repeating my question, since I didn't hear from anybody, so I assume that I didn't ask it the right way. Here it is: If you want to connect AS 100 to AS 300 or multiple AS's what are different ways that we can do it? We can use BGP. But I saw this question asking that know "other ways" to make connection between different AS rather using BGP. What they could be if they are not EGP? I saw this question under the new objectives for Routing 2.0. I would be really thankful if anybody can clear my understanding for this Routing question. Best regards, Maria As Bill Clinton might say, that depends on how you define "autonomous system." If you look at RFC 1930 and the general interpretation by the registries that assign AS numbers, a registered AS: -- is a set of addresses (and routers) -- under one or more administrations -- presents a common routing policy to the Internet -- announces that policy with BGP-4 (Additional practical guidelines from the registries) -- connects (or will connect in 1 month) to 2 or more other AS -- upstream connections of at least T1 speed So, in what I think is the most pure definition, BGP-4 is the only way to interconnect true AS. A special case of interconnection is from a customer network with a private AS number to an upstream provider with a public AS number. Such connections use BGP-4, and the Internet properly sees only announcements originating from the public AS. Another special case is a BGP confederation, in which multiple AS with private AS numbers communicate with BGP, and, if there are any announcements to the general Internet, remove the private AS numbers and show the origin as the registered AS. Now, there are older usages of the term AS, and you will see them associated with Cisco discussions of interior routing protocols. The older definition essentially considers an AS: -- a set of addresses (and routers) -- under one administration -- uses common internal metrics and routing policy Under this definition, IGRP and EIGRP can create AS that do not exchange routes without explicit redistribution. By putting IGRP and EIGRP in the same AS number, you can get automatic redistribution. OSPF also uses an older definition of AS, which really means the set of addresses and routers that are in, or connect to, a single area 0.0.0.0. Even if a route comes in from another OSPF process, it must come in through an "ASBR". The OSPF, and generally (E)IGRP, usages of "AS" are much closer to what the IETF would call a "routing realm" or "routing domain". Historically, Cisco courses and tests do not use this term, although you'll see it in Cisco contributions to the IETF. A final comment -- an enterprise that connects to a single service provider using static/default routing on its side is part of the provider's AS. ___ 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]

Re: Layer 3 VS. Layer 2
"Rodney Jackson" [EMAIL PROTECTED] wrote, Guys, I need some help. Can someone please explain why Layer 3 Switching is faster than Layer 2 Switching? It seems to me that with L3 the switch would have to go up three layer instead of two. I may have whole concept so please explain. *sigh* the reason you are confused is that layer 3 switching is principally a marketing rather than a technical term. Relaying packets based on layer 3 information is routing. Relaying frames based on layer 2 information is bridging or frame/cell switching. Each of these levels has two components: Path determination May contain dynamic routing protocols Will contain configuration information Stores best paths in a Routing Information Base(RIB) that is optimized for efficient updating May create a Forwarding Information Base (FIB) that is optimized for speed of lookup. Alternatively, the RIB and FIB may be the same. Forwarding Makes forwarding decisions based on the contents of the FIB When hardware assisted and making layer 3 decisions, often is called layer 3 switching So a layer 3 switch is really a hardware-accelerated router. A layer 2 switch is faster than a traditional bridge, under most circumstances, because: It has a very fast internal forwarding fabric interconnecting its ports It uses microsegmentation on its user ports It usually will have a hardware-assisted FIB containing layer 2 information Things are getting more, not less, complex. Multiprotocol label switching (MPLS) or Cisco's tag switching makes forwarding decisions based on a label or tag, usually between the layer 2 and 3 headers. ___ 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]
Wild Card Mask Puzzle SOLUTION!!!!!!
Okay. There have been alot of responses to this. And alot of people wanting the answer. SO, let me mention Evgeny Babanin and Chuck Hwang, since they gave correct responses to the question! Congrats!! Now, I'll everyone's agony... =) The answer is: access-list 10 permit A.B.C.1 255.255.255.24 Here's the explanation: Remeber in the wildcard mask, for a given bit: 0 = must match the same bit in the source address given 1 = doesn't matter what it is I will use A.B.C.1 for the source address in the access-list command since (as we see below) the least significant should always be 1. Below I have the binary version of our address 0.0.0.1: aaa aaa.bbb bbb.ccc ccc. 0001 - least significant bit = 1, thus the decimal value of that octect is 1. This is crutial because this is the only non-zero bit in the source address. We'll use that later. Limiting ourselves to looking at the last octet of the target IPs we want to let through, 0001 = 1 1001 = 9 0001 0001 = 17 0001 1001 = 25 --- So since the last bit ( xxx1) has to = 1 (like in the source address), it's corresponding wildcard bit must = 0 so we know the wildcard mask so far has to be xxx0 (last octect only) we also know that bits (from right to left) 2, 3, 6, 7, 8 HAVE to be = 0 (so they match the zeros in the source address), so therefore their corresponding bits in the wildcard mask must be = 0. So now we have: 000x x000 (last octect only) When looking at bit 4 and 5 we see that they could be either 0 or 1. Any of the four combinations of 0 and 1 give us the four target addresses, so their bits in the wildcard mask are = 1. So our final wildcard mask will be 0001 1000 (last octect only) = 24 (decimal) So.. the following command is the correct answer: access-list 10 permit A.B.C.1 255.255.255.24 It's a tough question,..

Re: Wild Card Mask Puzzle SOLUTION!!!!!!
Thanks, Evgeny. My answer had that mask 0.0.0.24, which would only allow
specific hosts on a specific subnet. If the original question was to allow
any host witha 1,9,17, or 25 in the last octect--but from any subnet--then
255.255.255.24 would be the correct answer.
It all depends on how the original question was worded. Regardless, the
trickiest part was the mask on the last octect. Good question!!
We need to make this a regular thing, that was a lot of fun.
John
Michael,
Thanks a lto for mentioning my name, but
I've just looked through follow-ups and found out that John Neiberger was
the first to give correct answer.

Okay. There have been alot of responses to this. And alot of people
wanting the answer.
SO, let me mention Evgeny Babanin and Chuck Hwang, since they gave
correct
responses to the question! Congrats!!
Now, I'll everyone's agony... =)
The answer is:
access-list 10 permit A.B.C.1 255.255.255.24
Here's the explanation:
Remeber in the wildcard mask, for a given bit:
0 = must match the same bit in the source address given
1 = doesn't matter what it is
I will use A.B.C.1 for the source address in the access-list command
since
(as we see below) the least significant should always be 1. Below I
have
the binary version of our address 0.0.0.1:
aaa aaa.bbb bbb.ccc ccc. 0001 - least significant bit = 1, thus
the decimal value of that octect is 1. This is crutial because this is
the
only non-zero bit in the source address. We'll use that later.
Limiting ourselves to looking at the last octet of the target IPs we
want
to
let through,
0001 = 1
1001 = 9
0001 0001 = 17
0001 1001 = 25
---
So since the last bit ( xxx1) has to = 1 (like in the source
address),
it's corresponding wildcard bit must = 0
so we know the wildcard mask so far has to be xxx0 (last octect
only)
we also know that bits (from right to left) 2, 3, 6, 7, 8 HAVE to be =
0
(so
they match the zeros in the source address), so therefore their
corresponding bits in the wildcard mask must be = 0. So now we have:
000x x000 (last octect only)
When looking at bit 4 and 5 we see that they could be either 0 or 1.
Any
of
the
four combinations of 0 and 1 give us the four target addresses, so
their bits in the wildcard mask are = 1. So our final wildcard mask
will
be
0001 1000 (last octect only) = 24 (decimal)
So.. the following command is the correct answer:
access-list 10 permit A.B.C.1 255.255.255.24
It's a tough question,.. That's why it's fun =) Thanks to everyone
that
participated!
Mike W.
PS: Alrighty Chuck. we're ready for the next question =)
Puzzle posed by Mike Williams:
Make a (single line) access-list that will only allow traffic from
addresses
matching the following model:
x.x.x.1
x.x.x.9
x.x.x.17
x.x.x.25
It's along the same lines as the question you posed, but a little
more
challenging since you only want those 4 addresses to pass
through.
=)

RE: CCNP certification
Right now you can't take foundation, so depending on your timing you will have to take all 4 exams. Other than that, it's up to your exam taking tastes. Do you like longer or shorter exams?

RE: Spanning Tree
Title: Spanning Tree Well, I'm studying for Switching 2.0 so I may be wrong. The way I see it, the root port is the "upstream" port (this is tree, so there are upstream and downstream ports) while the designated ports are "downstream" ports, so conf BPDU flow from the root bridge, to the root port on the downstream bridge, to the designated port on same bridge, to the root on next bridge, and so on. Same thing with frames, they go upward to the root and downward from there to the right branch and leave Francisco Muniz. Hi, all. First of all, I just want to test if I'm able to post on the forum at all since I don't see any responses to my first posting. If this goes through, can someone tell me why would Spanning Tree Algorithm need a designated port when the root port has already been established as the least cost path to the Root Bridge? Thanks.
Re: Looking for CVOICE Books
The following are my own personal opinions and observations and are not meant to represent the official views of the company that I work for. I have recently passed CVOICE 1.0 A few personal comments: The exam I sat was based very heavily upon CVOICE course notes. So a set of CVOICE course notes are essential. It is not too difficult.

Re: Set up question
You need to call phone company for both the frame realay, and for a DLCI to map your pvc to isp. I have a suggestion though. Why doesn't your company get DSL at the branch (and even hq) then use an IPSEC VPN to tunnel to the branch and vice versa. If your branch is going to come to the HQ to use internet your gonna soak up all the bandwidth anyway. In the scenario here, you both get high speed to the internet and each other using the tunnel through the internet. - Original Message - From: Arun Upadhyay [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, July 03, 2000 10:13 PM Subject: Set up question Hi Friends I have a question, if someone can help me I will highly appreciate. My office ( HQ ) is having Frame relay connection. Now they want to connect one more branch office with this office using Frame relay .But they want all the branch office people to access internet using the existing Frame relay connection at the HQ office.

RE: Wild Card Mask Puzzle SOLUTION!!!!!!
Two points. 1) always be careful with the wording of questions. There are two correct answers, depending upon how one interprets the question. Access-list 10 permit 0.0.0.1 255.255.255.24 is indeed correct IF you want to permit only the values of 1,9,17,and 25 in the last octet of ANY network, whether that be 192.168.1.x or 10.0.0.x etc Access-list 10 permit a.b.c.1 0.0.0.24 is indeed correct IF you want to permit only hosts with 1,9,17,25 in the last octet from a SPECIFIC network.

My answer had that mask 0.0.0.24, which would only allow specific hosts on a specific subnet. If the original question was to allow any host witha 1,9,17, or 25 in the last octect--but from any subnet--then 255.255.255.24 would be the correct answer. It all depends on how the original question was worded. Regardless, the trickiest part was the mask on the last octect. Good question!! We need to make this a regular thing, that was a lot of fun.

And alot of people wanting the answer. SO, let me mention Evgeny Babanin and Chuck Hwang, since they gave correct responses to the question! Congrats!! Now, I'll everyone's agony... =) The answer is: access-list 10 permit A.B.C.1 255.255.255.24 Here's the explanation: Remeber in the wildcard mask, for a given bit: 0 = must match the same bit in the source address given 1 = doesn't matter what it is I will use A.B.C.1 for the source address in the access-list command since (as we see below) the least significant should always be 1. Below I have the binary version of our address 0.0.0.1: aaa aaa.bbb bbb.ccc ccc. 0001 - least significant bit = 1, thus the decimal value of that octect is 1. This is crutial because this is the only non-zero bit in the source address. We'll use that later. Limiting ourselves to looking at the last octet of the target IPs we want to let through, 0001 = 1 1001 = 9 0001 0001 = 17 0001 1001 = 25 --- So since the last bit ( xxx1) has to = 1 (like in the source address), it's corresponding wildcard bit must = 0 so we know the wildcard mask so far has to be xxx0 (last octect only) we also know that bits (from right to left) 2, 3, 6, 7, 8 HAVE to be = 0 (so they match the zeros in the source address), so therefore their corresponding bits in the wildcard mask must be = 0. So now we have: 000x x000 (last octect only) When looking at bit 4 and 5 we see that they could be either 0 or 1. Any of the four combinations of 0 and 1 give us the four target addresses, so their bits in the wildcard mask are = 1. So our final wildcard mask will be 0001 1000 (last octect only) = 24 (decimal) So.. the following command is the correct answer: access-list 10 permit A.B.C.1 255.255.255.24 It's a tough question,..

More puzzles - OSPF Network statements
Gee, the recent wildcard mask puzzle was so much fun, let's do it again. The problem revolves around the OSPF network statement. Given an OSPF routing process, what are the fewest number of network statements that will incorporate the following networks into the given OSPF process? For example: router OSPF 100 Network a.b.c.d w.x.y.z area 0.0.0.0 Network b.c.d.e u.v.w.x area 0.0.0.0 etc Assume that all networks are in the same area ( for simplicity sake ) You may also assume ( for simplicity sake ) that the particular interface on which each particular network resides is the first host address on that network. For example, on network 10.10.3.0/24, the first host address ( and therefore the interface address ) is 10.10.3.1 Networks are as follows: 10.10.3.0 /24 10.25.17.0 /16 10.51.100.192 /26 172.16.0.0 /16 172.16.100.0 /24 172.16.210.240 /28 172.27.32.0 /19 192.168.0.0 /24 192.168.1.0 /30 192.168.207.56 /29 remember - accolades go to the one who can enter all of these networks into a single ospf process with the fewest possible network statements.

Ports for Internet Mail
Let's use this scenario. 1. The clients are inside the corporate network, with private IP. Let's say 192.168.1.0, public range 202.166.1.0/28. The router is doing dynamic NAT. 2. The E-mail server is in the ISP. 3. Primary DNS is inside corporate network. I use following access-list, however the clients could not access internet mail. Is there any more ports I should open?

Dark side of the puzzle More puzzles - OSPF Network statements
Chuck, I agree that problems like this do provide practice in masking. Let's make very sure, however, not to give the impression that minimizing the number of statements -- definitely OSPF network, and arguably access lists -- is a good idea for the real world. Consider the situation when one is called in, at 3AM, to troubleshoot a mission-critical network. And, as you look at the configuration in the routers having problems, you find nothing but "cute" statements, with no documentation. Personally, I make a point of having one OSPF network statement for each interface I want to speak OSPF. Much easier to understand, and there is no performance advantage to having a lesser number of statements. Even with access lists, I don't try to minimize except when I am facing a real performance problem that can't be solved any other way. The original Sprint access list that imposed their prefix length restrictions, IIRC, was 16 pages long. Gee, the recent wildcard mask puzzle was so much fun, let's do it again.

Re: 4000 router boot TFTP
Hi Jim, Usually if your ethernet interface on the 4000 is plugged into a dumb hub, then when you boot up the 4000, it should bring up the ethernet interface pretty fast which should allow the 4000 to talk to the tftp server(10.1.1.9 in your case) right away. Unless you plug your 4000's ethernet interface into one of those catalyst switches( like the 19xx, 29xx, 35xx, etc..), then it takes about 30 seconds for the "autonegotiation" for speed and duplex-mode to sync up. If you're using a catalyst, then an easy way go into the switch and enable spanningtree portfast. Hope it'll help you. Luan T.

Can someone please explain why Layer 3 Switching is faster than Layer 2 Switching? It seems to me that with L3 the switch would have to go up three layer instead of two. I may have whole concept so please explain. *sigh* the reason you are confused is that layer 3 switching is principally a marketing rather than a technical term. Relaying packets based on layer 3 information is routing. Relaying frames based on layer 2 information is bridging or frame/cell switching. Each of these levels has two components: Path determination May contain dynamic routing protocols Will contain configuration information Stores best paths in a Routing Information Base(RIB) that is optimized for efficient updating May create a Forwarding Information Base (FIB) that is optimized for speed of lookup. Alternatively, the RIB and FIB may be the same. Forwarding Makes forwarding decisions based on the contents of the FIB When hardware assisted and making layer 3 decisions, often is called layer 3 switching So a layer 3 switch is really a hardware-accelerated router. A layer 2 switch is faster than a traditional bridge, under most circumstances, because: It has a very fast internal forwarding fabric interconnecting its ports It uses microsegmentation on its user ports It usually will have a hardware-assisted FIB containing layer 2 information Things are getting more, not less, complex. Multiprotocol label switching (MPLS) or Cisco's tag switching makes forwarding decisions based on a label or tag, usually between the layer 2 and 3 headers. ___ 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] Priscilla Oppenheimer http://www.priscilla.com ___ 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]

I setup dial-up networking on another laptop and it does the same thing. However, this one seems to work with IE5 (I can surf the net). I dont get the whole subnet mask thing. Ive tried just about everything in the book and I still get the classfull subnet mask every time. (I tried different routers, different versions of IOS, etc, same thing every time). Ive tried the async-bootp sub command etc. nada -Brad - Original Message - From: "Olden Pieterse" [EMAIL PROTECTED] To: "'Brad Ellis'" [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Sent: Wednesday, July 05, 2000 1:15 AM Subject: RE: dial up to 2501 AUX port Hi there Brad Your helper addresses all set up ok ?

Re: Internal T1 WIC
It is common with physical interface frame relay or multipoint that you can't ping your own interface, but I've not seen this with ptp. To make self ping work on phy/mp, add a frame map with your local ip and use any valid dlci.

I have a situation where a 1601 R 12.0 (3) is on ptp frame at frac T with 1 channel assigned...Everything works but I can't ping the private ip using Class A.However the E0 side pings and works fine but can't emulate NAT... Why can't I ping inband on the serial? I have tried numerous settings but to no help.I am using internal T1 WIC and all routes are occuring using ip and ipx..Can see both cdp neigh and both remote Netware servers...I have never seen where you could console in and not ping serial but it would work and route fine... ___ 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]
