So I have made some more findings about Dynamips Running more hypervisors is not more effecient than running one, will load balance over cores anyway GNS3 is just a hassle, stick with Dynagen if you have a set topology This
Dynamips – loadbalanced hypervisors
As most CCIE candidates know Dynamips runs much better on Linux. Many of us run Windows at work or as our primary OS and might be afraid to mess around with partitioning and dual booting. There is a safer alternative

IP services – Notes
ARP Address Resolution Protocol, used to discovery layer two address when IP address is already known. Uses protocol 0x0806 compared to Ethernet which uses 0x0800. At layer two an ARP request is a broadcast since the MAC address of the
Spanning tree – notes
Electing the root Only one switch can be the root bridge. From the start all switches announce themselves as the root, when a switch hears of a superior BPDU it stops announcing itself as the root and instead forwards the
VLAN – Notes
Private VLANs Commonly used in SP networks to put users in common subnet but no direct forwarding of packets between customers in same VLAN. Enforce security by forcing traffic to go through router instead of switched locally. There are three
Ethernet – notes
RJ 45 pinouts 10-BASE-T and 100BASE-TX uses pairs two and three, gigabit Ethernet uses all four pairs. Pinout for straight cable: 1-1;2-2;3-3;6-6 Pinout for crossover cable: 1-3;2-6;3-1;6-2 A standard PC transmits on pair one and two and receives on three
