Cisco vs. HP ProCurve VLAN switch ports

Usually, when Cisco oriented networker sets off to the HP networking world, first confusing thing is VLAN port assignment. When speaking about VLAN ports in HP world, the ports can be tagged or untagged (despite the access / trunk ports in Cisco). As you may guess, tagging means 802.1q tagging in Ethernet frames. It is important to realize that Cisco is “port-centric”, whereas Procurve is is “vlan-centric” when speaking about

IPv6 Mobility testing topology

For better understanding and demonstrating of IPv6 mobility mechanisms I designed this simple but sufficient network topology. You can check it on the picture below. I used three routers to describe the mobility process, although one router with three connected networks should be also enough. However, with more routers you can easier monitor and trace the differences between direct and indirect communications with mobile node. There is connected one network switching device
