Hello Marwan,

We are currently working on a migration plan between existing data center distribution with 6509 and new DC distribution that's going to be nexus 7K.  What is the best way to integrate those two systems for the migration purposes? 

thank you


Hi Henry,

there are several ways for integrating Nexus with 6500 for migration purposes

first you need to align this integration with your DC systems and its migration plan, for example will be any vlan to be extended between the two systems or not

in case you need to extend some vlans or all and assuming you are using VSS on the 6500 side and vPC on the nexus side you can connect VSS to vPC using MEC between the two systems

or if you are not using VSS on the 6500 side then you will need to use normal L2 trunk links between the two systems and use STP to control which link is forwarding and which link is blocking to avoid L2 loops assuming you will be using multiple links to multiple N7Ks

hope this helps
