Real World eXperienCe


Today I were engaged in a deployment for cisco 2821, The router was ordered with HSEC bundle which do comes with ADV IP SERVICES IOS along with VPN accleration card. By the passage of time i realize that how important the real world experience is. The deployment was simple I copy the old router configuration modified it and pasted it to new router. That's it !!!

Althogh i need to configure BGP multiohoming too. The customer has one wimax link nad other DSL, both from link DOT net and they want to ensure that automatic switch over to second link. I thought that i can just give two default route and change AD for both and that would work but the problem is that both link are terminating on Rj45 ethernet so either i have to use BGP or IP SLA monitor. I will explore it in depth to see what works better.

The REAL world notes:
1- When i booted the brand new router it enters in ROMMON mode and i were wondering why it happens and a mighty REBOOT makes the job for me and normalize every thing.

2- Somehow I lost user name after configuring router and fortuntely worldcall EVDO (USB internet) do the maigc for me. I Google for password reset 2800 and found
Press Break key on keyboard when reboor router.
In Rommon1 > Rebbot and give ansower no to every question
type # confreg 0x2142

Now saved config is ignored

type # copy start run
do the changes as needed and remember to do No shut on interfaces

#config-register 0x2102

#copy run start
Thats all I enjoyed every bit of it, the network integration really makes me crazy no matter how small the deployment is, i enjoyed it. Last but not the least USB internet is a blessing for network engineer. Grab it if you can.............
