i ping from my pc to router,but my router does not ping pc,after watching this video i turn off my firewall and finally get icmp echo reply packets ,great man
Would it be possible to create more than 1xMicrosoft Loopback adapter if for example you wanted to create a GNS3 lab that incorporates your Host PC providing connectivity to the internet for both GNS3 & various virtual PC/Servers (Microsoft Virtual Server 2005/Virtual Box..etc)running for example Exchange Server 2007/2010 which is connected to GNS3 routers.(For the moment I'm using Qemu & Tinycore)
It is difficult to find info about Loopback adapters/connectors, WHY & HOW to use them.
Keith, first of all i thank you for the videos you post and hope you have the time to post more, especially on request. Please i have a problem which involves getting the ios image i need to use "gns3".
please i appreciate the the time and effort you put in posting to youtube.
Cisco licenses their IOS to customers who purchase their products. They haven't taken a "firm stand" on individuals who also use this IOS withing GNS3 for testing/practicing. I can't give away the IOS images, as I don't have the legal right to do that. If your company has an IOS router, I would start by talking to the IT people there and ask them for assistance.
Keith, I can't seem to get my persistent route to save. Otherwise, I can ping the "initial" router that connects to the cloud, but nothing behind it. Would you mind posting your working configuration with a static route created in windows, thus allowing full connectivity to your virtual environment? I'd appreciate it...
@cyberpsych1 Cool- Let's say we have the cloud connected to R1, with the pc using 10.0.0.2, and the router using 10.0.0.1 and the 23.0.0.0/24 network is on the other side of R1. On PC- route add 23.0.0.0 mask 255.255.255.0 10.0.0.1 -p route print (to see results) Make sure that routers behind R1 know how to route back to the 10.0.0.0 network, (to return packets to the PC). On all routers: router eigrp 1 no auto net 0.0.0.0 Best wishes, Keith
Hi Keith, Can I have one loopback 9.0.0.9 and another loopback 11.0.0.9 hanging off the same router and made to send traffic THROUGH the router instead of just being able to logically ping it ?(Sine both 9.0.0.9 and 11.0.0.9 are available in the same PC's routing table, will traffic between them be logical or go through the attached router?)
If the PC thinks it is directly connected to both the 9.x.x.x and 11.x.x.x network, it would never try to forward traffic through the router, if the destination was either network. If you want to send traffic through the router, disable the loopback on the 11.x.x.x network, and configure a route with the route add command on your computer, to use the router 9.x.x.x address as the route to reach the 11.x.x.x, then your traffic will go through the router.
i am unable to ping from 9001 to 9009 but from 9009 to 9001 i can Basically I am testing two vlans between primary and secondary l3 switch or routers so that one vlan goes down other vlan comes in to play. Secondly i am unable to complete route add 10 0 0 1 25525500 9001 -p option since becoz its asking me elivation required

Not to worry I saw in another video that I needed to restart my laptop in order for GNS3 would recognize the new adapter. As soon as I did this and opened up GNS3 and configured my cloud my loopback adapter was the first option in the selection window. I hope this piece of information will help someone else who may run into a similar problem.
I did everything that you instructed people to do in your video. However when I tried to configure my cloud my loopback adapter was not listed. Why is this? It shows up with the other adapters in the network connections screen in the control panel. I diagnosed it for problems and none were found. So I am kind of perplexed as to why it isn't appearing in my cloud. I am running GNS3 on a Windows 7 HP edition HP Laptop. Please let me know what I need to do to resolve this. Thank you.

*Heh* I forgot to turn off "auto summary" when I configured EIGRP using Frame Relay earlier (D-oh!!!!) Thanks for that; all is good now...

just FYI...if you dont see any option in GNS3 Cloud Configure window under NIO Ethernet...then follow the below solution:
Run GNS3 as Administrator which is right click your GNS3 file and click Run as administrator.
It will save you a big headache.
