Routing between two nexus 5k best practice

[netspazz]

I have a quick question, and confused on how the best way to do routing between 2 5k's.

5k-1 let's say has vlan 10, 20, and 30

5k-2 let's say has vlan 40, 50 and 60

I need to route between them and I have 2 options or ways to proceed.

1. configure a routed interface on both devices and assign a x.x.x.x\30, typical router configuration.

2. configure svi on both devices, say vlan100 and assign a x.x.x.x\30.

Both ways would seem to work, but which way is best and why?

Am I missing something? also am currently using ospf withing the network if this helps.

thanks

Usually routed links are considered better when routing between routers. One reason for this, a routed link won't throw L2 stuff out the port as it would if you used an SVI.

Even if you have several routers to interconnect, sometime routed ports are still considered better, for one reason, each can have a different cost metric, and multicast won't flood to all the other routers. (The latter is also mitigated by Cisco's PIM snooping.)
