RE: HSRP - hows it work [7:24721]
Hi group, Who have used the 'standby track serial 0' command before, while configuring HSRP. I tried it and was disappointed because, my two upstream providers are connected via a radio (microwave link). Even when one of them is down, the radio coneected to the router still send keepalives to the route and as such the interface does not go down, and as such the HSRP does not work when any of the upstream goes down. Has anyone being able to solve this problem?

Multihoming Without BGP!!!!!....How Posible???? [7:20305]
Hi all, first let me pay tribute to my numerous Networking colleagues, who lost their life while in active service at WTC and Pentagon that fatefull Tuesday and may God grant their love ones in this group the courage to bear the lost. I stand with the popular side 'Terrorism must be completely stamped out' I will need some help with this configuration am proposing. I want to implement multihoming for one of my clients and I do not want to use BGP at all neither do I want to ask each of my upstream providers to route the other provider's Set of IP Addresses given to me, through its own Network. I have two Routers called RouterA and RouterB. RouterA have three ethernet ports (EA1, EA2 and EA3), while RouterB have two ethernet ports (EB1 and EB2). My two upstream providers (ISPs) are Source1 with IP address 63.98.9.0 255.255.255.0 and Source2 with IP address 100.10.10.0 255.255.255.0. Source1's link is terminated on port EA1 on RouterA while Source2's link is terminated on port EA2 on RouterA as well. Port EA3 on RouterA is connected to port EB1 on RouterB, while Port EB2 on RouterB is connected to my Access layer Switch. That is the schematic above, my proposed configuration is stated below: RouterA(Config)#Interface EA1 RouterA(Config-inf)#IP Address 63.98.9.1 255.255.255.0 FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Undefined Port Adapter type 55 at bay 1 [7:20112]
Hi, I have a 2621 router with 8M flash and 32M Ram. I inserted a network module with 1 ethernet port into it, the IOS 12.0 did not recognize it. It only sees the FastEthernet ports that came with the router. Upgrading the memory to 64M did not help issues, Changing the module with two other onces did not help the situation. However, the IOS keep saying that the Adapter ports are undefined. Looking forward to your response. Regards. Oletu __ Terrorist Attacks on U.S. - How can you help?

However, the book did not give stratacom switches any treament except for a few lines and they test this area heavyly I learnt in the exam. I have done a lot of searches even in CCO but could not locate any white paper on this subject. Please, help with a link or URL where I can get a white paper on this switch. The URL provided in the cisco press book did not help issues and on CCO, the only thing I saw was how Cisco aquire stratacom in 1996, I wonder whether they will ask one that in the exam.

Where is the Missig Link [7:7304]
Hi Group, Please if you can just drop a line across to me, it might really help me. Has any one install a 2600 series router at the other end of a microwave radio link through the ethernet port be it 0/0 or 0/1? I have tried this on several occasions but it would not work, for reasons I have not found out. The setup is like this. I have a microwave radio link which is perfect. If you connect your computer to the the radio through a cross-over cable you would browse the net fine. My desire is to place this client in a different subnet/network. I introduce a router in place of the computer connecting to e0/0 of the 2600 using a cross-over cable. The other e0/1 of the router is then connected to the computer using another cross-over cable. The radio is getting its link from another router whose ip-address is 64.86.155.221/28, the radio's ip-address is 64.86.155.155/28, the e0/0 interface of the 2600 is 64.86.155.156/28, the e0/1 is 192.168.0.1/24. The routing protocol is 'igrp 200'. After the above configurations, the best I can get is the replication of all the routes learned by this router from the other one over the microwave radio link, but my computer can browse the net. Remove the 2600 router and plug the computer straigt into the radio you would be able to browse the net. This is my dilemma. The questions that race through my mind without answer are: 1. Is it that I can't use the interface e0/0 and e0/1 to make a WAN link over a microwave radio? 2. Do I need to install an ethernet interface WAN module in the WAN slot provided in the router. 3. Are mine just missing something. 4. Please remind me of what the missing link seem like. Thanks in advance. Regards. Oletu H. G. __ Do You Yahoo!? Get personalized email addresses from Yahoo!

Hi All, Am bill to write this exam next week. I need some helping tips: 1. What is the pass mark for the exam? 2. Am using the Cisco press book for BCMSN by Karen Webb. Is this book enough? Surprising, this book did not cover topics like DDR, Cisco TAC/CCO, ATM/LANE, etc which I gather from cisco site that are some of the test areas. Should I forget about these and just concentrate on the cisco press book or I should get other additional materials? 3. What is the difficulty level of the exam when compared with BCSN?

WAN Connection Through Ethernet Interface [7:1955]
Hi, Is it possible for me to connect a production WAN interconnecting two cisco routers with a microwave radio link in between through their ethernet interface? Or must it be through the serial interface. I have a cisco 2621 and 2511, with no add-on card. Which means, I just have 2 fastethernet interfaces on the 2621 and 1 serial interface with 1 ethernet interface on the 2511. The serial interface on the 2511 has been connected to another WAN. Am implementing a second WAN connection from the ethernet interface of the 2511 through a microwave radio-link using speedlan radios to 1 of the fastethernet interfaces in the 2621. After everything, 'show cdp neighbor' works fine on both routers. 'show ip route' also works fine on both router. Pinging is okay. But from does prompt in a workstaion attached to the 2611 router through a 3com switch 'tracert' did not work, though 'ping' works fine and I can not browse the ethernet either. What might be the problem? What am I missing out? Or is it that WAN connectivity can only be achieved through serial interface connection? ..?? Many questions, few answers. Regards. Oletu.

Strange Configuration, Strange Result [7:1763]
Am trying to connect two cisco routers each on both side of two speedlan radios and antenna. In place of the second router was a 3com switch before now, and with that connection I can browse the internet. I now replace the switch with a router, the connection from the radio into the router was made using a cross connect rj45 cable. After all configuration, show ip route duplicates all the routes from the first router into the second router. Everything seem okay. But outside the route I cannot browse the internet. Both routers were connected together via the radios through their ethernet interfaces. The questions now is, 1. Can't I connect two routers via a radio through their ethernet interfaces? 2. If the answer is NO, why then was 'show cdp neighbor' showed me the second router, why was the line protocol up, why was the routing table forwarded to my second router? 3. Is there anything I am missingup? Thanks Oletu H. G.

Sorry, Snapshot routing is purely for Distant vector routng protocols, so eigrp is out of it. Static routes will solve your problem. Thanks Oletu H. G. Guys, I know that snapshot routing support RIP and IGRP but .does EIGRP support snapshot routing? I had configure EIGRP and snapshot. But seems snapshot routing got no effect on EIGRP. When the snapshot is in quiet status, eigrp continuous keeping the ISDN link up. If snapshot does not works on EIGRP then is it only static route can be used to keep ISDN link quiet?
