vpc topology help for nexus 7k

[sampathkumar.s]

hi team,

i have attached topology 1 and topology 2 for nexus 7k for vpc scenario.

Access switches got only 2 x 10 g capacity to Nexus switches.

What are the benefits in topology 1 and topology?

In topology 2, inter-switch links can be possible only through gigabit link rather than 10G links.

Hi Sampath,

Both topology looks good.

The only thing which i can say is that the topology 2 is awesome as you would have the Access switch redundancy available, Were as in Top1 you dont have that.

Incase something breaks down(Example: Links to the Nexus goes down from Switch1 you would have the backup way to reach the external network using switch 2.)

HTH

Are your access switches full switches or FEXs? If they are full switches these topologies are essentially the same, you just have more access switches in the second configuration. What device are you using for the access switches? If they are VPC capable, you could aggregate all four links into one bundle.
