RE: Redis. classful to classless. [7:66905]
You can summarize the non-classful routes using the area range command at the ingress point inside the ospf domain. OSPF would pass these classful (summarized) routes into IGRP. IGRP will then be able to interpret these as valid routes.

RE: CCIE written exam passed! [7:66364]
My heartiest congratulations to you. You're half-way through the CCIE cloud. It'll be sunshine pretty soon. Start preparing by gathering up some routers (4 to 6 routers would be ideal), preferably an IOS L-3 switch, and a bunch of serial and LAN cables. Start reviewing from the ground up, ie. perfect your FR skills before tackling OSPF. Then get yourself a copy (if you haven't got them already) of Jeff Doyle's Routing TCP/IP Vol. 1 and 2 books. Also, Internet Routing Architectures by Sam Halabi. It's a very good BGP book. Good luck on your preparation.

RE: SPAN on 2948G [7:66403]
Here's the command structure:
set span {_mod/src_ports | src_vlan | sc0} dest_mod/dest_port [rx | tx |
both] [inpkts {enable | disable}] [learning {enable | disable}] [multicast
{enable | disable}] [create]
Ex. You want ports 3/1 to be the source and 2/4 to be the monitoring port:
set span 3/1 2/4
Also, you can set the whole VLAN to be the SPAN source:
set span 12 2/4
where 12 is the VLAN number.

Re: Console management [7:66405]
I'm using a Cisco 2509-RJ. You can control up to 8 devices on it's async ports (9 if you'll be using the AUX port also). As the async prots are already RJ-45, you can connect Cisco's console cable directly.

RE: Console management [7:66405]
Yes. The 2511 can also be used. Though, you need an octal cable (8-async lines) or two (up to 16 asyncs) for it to be useful. However, in a practice lab environment, I'm sure you won't be configuring more than 8 or 9 devices. So a 2509-RJ is much more practical at least for me.

RE: SPAN on 2948G [7:66403]
I would presume that the 2948G you mentioned is the L2-only model. The Catalyst 2948G-L2 runs the same software as the Cat5000/5500, otherwise known as the CatOS. The Monitor command works only for IOS-based switches. The 2948G-L3 (L-3 switch running IOS) would probably use the Monitor command. Thought I'd clarify that.

Re: This is even better - RIP / OSPF redistributio [7:66057]
I concur with Henry D. Sometimes, the CCIE lab would ask you to do fairly stupid or unconventional things just so they'll know that you master that particular subject. In the CCIE practice lab example you provided, the author was probably trying to test your ability to redistribute between OSPF and RIP (and probably solve some routing issues especially if it's RIPv1), and your ability to block the routes efficiently and with the least number of commands. When I took my lab, I keep muttering to myself I can do this scenario much more efficiently than what it's asking me to do. But hey, it's their test questions and you have to comply to pass it. Can't argue with that fact. ;-) Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=66116t=66057 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
RE: ebgp vs ebgp multihop [7:66127]
One reason I can think of is that ebgp-multihop (in the lab) allows me to peer to a remote router's loopback interface. This can somewhat overcome situations wherein the main link can be down, but there still exists another link in which I can keep the neighborship up for whatever reason. As BGP runs on top of TCP, peering will still be up as long as there is another path to the remote router's loopback interface. ie. multi-homed BGP applications. I'm sure there are some more advantages and disadvantages of using such design in the real world. But I would guess that the guys from Cisco (or the geniuses who designed BGP), put ebgp-multihop in there as a feature not to be mandatorily used, but to overcome some unavoidable situations.

RE: ping things [7:66155]
You have a routing problem. Check your routing tables thouroughly. I'm sure you're missing some networks. The reason you're able to ping one-way is because you're using different sets of source and destination IP addresses when pinging from router A to router F, as compared to pinging from router F to router A. Use the extended ping command to see what I mean.

RE: Ref: PREVENT RIP ROUTING PROTOCOL FROM TRIGGER DIA [7:65482]
You may want to know if RIP indeed does trigger the dialing. So, to answer your 2nd question, use the command debug dialer packets to give you a rundown if RIP is considered an interesting traffic. If RIP is triggering your ISDN, you'll see a debug output similar to the following: 07:34:30: BR0/0 DDR: ip (s=192.168.0.1, d=255.255.255.255), 52 bytes, outgoing interesting (ip PERMIT) OR 07:35:49: BR0/0 DDR: ip (s=192.168.0.1, d=224.0.0.9), 52 bytes, outgoing interesting (ip PERMIT) The first output is shown that RIPv1 is considered interesting and is responsible for bringing up the ISDN line. The second output is a simillar condition using RIPv2. Now, to block RIP, you will have to instruct the router that RIP should not be treated as an interesting traffic. The way to do that is to put an access-list that denies RIP and permit all others on the dialer-list of the dialing router... Like so: access-list 101 deny udp any any eq rip access-list 101 permit ip any any dialer-list 1 protocol ip list 101 Doing a debug dialer packets again would yield the following: 07:41:40: BR0/0 DDR: ip (s=192.168.0.1, d=255.255.255.255), 72 bytes, outgoing uninteresting (list 101) OR for RIPv2 07:43:22: BR0/0 DDR: ip (s=192.168.0.1, d=224.0.0.9), 52 bytes, outgoing uninteresting (list 101) Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=65490t=65482 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

If it works without the SPIDs, don't use 'em. A SPID is just a profile of the options, keyset button layout, feature button layout, DNs, etc., assigned to an ISDN TE. (http://yarchive.net/phone/isdn_spids.html) It shouldn't interfere with any features supported by your router... ie. ecapsulation, authentication, encryption, etc. If it goes up and connects to the other line (with or without the SPIDs), treat it like any P-P link.

The range of addresses between 224.0.0.0 and 224.0.0.255, inclusive, is reserved for the use of routing protocols and other low-level topology discovery or maintenance protocols, such as gateway discovery and group membership reporting.

For the CIPT, you might want to enroll in a CIPT class, as you would need hands-on training in debugging and troubleshooting IP Telephony. Unless you have extensive experience on IP tel, you might want to consider taking the class.
