Avaya (Nortel) 8600 CPU utilization
It is recommended that you look at Nortel 8600 CPU utilization
While making changes in the network / Configuration
The problem is that the Graph scale allways changing and it hard to understand what is the Utilization
Online lab- Cisco & Juniper routers added
More cisco routers (7200 and 3600 with switch module) and a Juniper router added to Online lab
Now you can configure vlans and QOS at the cisco 3600 router
Online lab- Topology changed
I redesign the lab topology
Now the 2 Juniper and 2 Cisco routers are connected with OSPF,
The 2 Cisco routers are connected with EIGRP between them,
(redistribute routes into OSPF from EIGRP) The Debian64 server is now connected to the LAN of the Cisco routers
Feel free to make changes,
Configuration is reset in every 24 hours
