PGP Key [7:71873]
Hello again. I was curious if someone on this list could explain to me what is a PGP key? Sometimes I see emails with some sort of PGP key at the buttom and have no clue what its purpose is. What is its intended use for? How can I get one? Is it free? How to use it? Thanks kindly! __ Do you Yahoo!? SBC Yahoo!

RE: CCDA Study material [7:71111]
Great write up. Thanks. So what is the current exam number? Is it just one exam that I have to take? Do you know what the new exam number will be or is? I was looking at taking the following course, what do you think: http://www.knowledgenet.com/courselibrary/cisco/courses/desgn_pf.jsp Thank you! --- Priscilla Oppenheimer wrote: CiscoNewbie wrote: Hi all. I am going up for my CCDA cert and would like to know what are the recommended books and material to study with? Nothing is out yet for the new version of the test, as far as I know. Your best bet would be to take the instructor-led class, if you can afford it. With a good instructor, I think DESGN could be a really great class. It's got tons of meat now, much more than before. It has a big focus on systems analysis as it is taught at universities, as a real discipline, not just a bunch of hand-waving. The class also has a huge scope, covering almost everything you ever wanted to know related to campus and enterprise networks, from business (which they call social or organizational) goals, technical goals, topologies, architectures, modular design, addressing (including IPv6), routing, voice, network management, and security. One focus is on the SAFE architecture, so look that up on Cisco's site and learn it. There's also some AVVID stuff Many of the course modules are partially based on my book Top-Down Network Design. Many of the modules say that Top-Down Network Design is recommended reading. Top-Down Network Design doesn't cover some newer topics, though, such as SAFE and AVVID, although it did cover voice in a limited fashion, since Cisco has been harping on that for years now. DESGN covers voice in gory detail, however. It seems to have all of the old CVOICE course in it. Each module in DESGN has many chapters, each of which is literally hundreds of pages long. The person turning it into a book (not me unfortunately) is going to have a heyday. :-) I haven't taken the new test, but if it really tests all that's in the course, it's going to be one of the hardest tests out there (and that's a good thing. It's about time design got some respect. :-) Anyway, bottom line: if you can take the older version of the test, then there's lots of study materials. If you have to take the newer version, then you should take the instructor-led DESGN class or wait a few months for study material. Priscilla Thanks. - Do you Yahoo!? SBC Yahoo!

Re: OSPF Adjacency Question [7:66206]
Hi and thanks for your reply. I had already attempted what you suggested and still the adjacency does not come up. Can you (or any list member) clarify for me whether the network command along with the wildcard mask have to match exactly as the interface for which you are enabling OSPF is configured for? Would the use of the network statement as follows work as well: network xxx.xxx.xxx.14 0.0.0.3 area 1 or does it have to be netowrk aligned? When the hello packets are exchanged, the mask is also carried, so where does the router get the mask for the interface it is advertising? Is it derived from the network statement? Can someone explain what the error that I was seeing means? Thanks.

Question on ISIS and IP Mismatches - 2nd attempt [7:64381]
Hi all. I am thinking of adding a few Cisco into my lab which consist of mainly Juniper routers running ISIS. A few months back I got caught up in a nice troubleshooting issue with ISIS on these routers while working on a PTP in that I had misconfigured an IP address on one side of an interface and a different network IP on the other side of the PTP. Being that ISIS does not care about IP, the adjacencies forms anyways like they should have. Now I know that this is the nature of ISIS and not an issue with the router but recently Juniper modified their JUNOS OS so that it checks for proper match of IP parameters. My question is, does Cisco have this built in behavior in that it will check for this mismatch? If so, what IOS code/train has it? Thanks. - Do you Yahoo!? Yahoo!

Help with Route-Maps [7:63381]
Hi all. Here is a scneario that I need your help on: I have a RAS server that has 2 ethernet interfaces for egress traffic. The IP addressing on each interface are on separate networks. In addition, the dialin pools configured on the RAS are in separate networks from each other as well as from those defined on the ethernet interfaces of the RAS. Each Ethernet interface gateway points to a Cisco 2620 router which each of the routers have their own connection to the internet via 2 separate providers. No BGP being done. The IP Pool addressing on the RAS server are from each of the providers. So Pool A IPs are from Sprint and Pool B are from Choice1. So in the event that one dialin user gets an IP from Pool B but gets routed to Router A, the user will not go any where because each provider will not route the other provider IPs. My goal was to be able to say on the RAS that pool A goes out of ethernet port 1 and Pool B goes out ethernet port 2 but the RAS solution that I am using will not allow this to be done. So I thought about creating a route-map on the Cisco's to be applied to the ethernet interface (ingress) as an inbound policy. The route-map on Router A would need to say something like: If Pool B which belongs to Router B, then set IP next-hop to Router B ethernet interface. Both routers know about each other. I would like to know if all I would need to do is the following or if I need something else or maybe I cant do it. Thanks. Here is what I come up with: ROUTER A: route-map from-RAS permit 10 match ip address 1 set ip next-hop 192.168.1.2 interface Ethernet 0/0 description Traffic from Pool A ip address 192.168.1.1 255.255.255.0 no ip directed-broadcast ip policy route-map from-RAS access-list 1 permit The same will be done on the ROUTER B but with the appropriate IPs.

RE: Help with Route-Maps [7:63381]
Thanks Darrell for your response and sufggestions. To respond to your suggestions: The RAS server that I am using is a non Cisco. The options they have available to do this is through Radius and the Radius server is owned by someone else. So this Radius solution they have is not feasible. So my only option is doing it on the Cisco's. Both Cisco's have routes back to the ethernet interface of the RAS. The WAN links on the routers are T1's. Thanks fr your help. - Do you Yahoo!? Yahoo!
