This is a simple how to make a nexus switch L3 routeing and the connected access switches still on L2 switching. If you have a router connected between internet and the router switch. Make shure you have a static route configured to the two vlan network.

Router Switch

no system default interface-vlan autostate (brings up the vlan)

conf t

vlan 10  (creates vlan 10 L2)

name Servers vlan 10

exit

vlan 20 (creates vlan 20 L2)

name Servers vlan 20

exit

feature interface-vlan  (Converts L2 vlan 10 to L3 vlan 10)

interface vlan 10

ipv6 address 2001:db8::/50

no ip redirects

exit

feature interface-vlan  (Converts L2 vlan 20 to L3 vlan 20)

interface vlan 20

ipv6 address 2001db8:0:4000::/50

no ip redirects

exit

interface ethernet 1/1 (creates tagged vlan port to access sw1)

description To Access Sw1

switchport mode trunk

no shutdown

exit

interface ethernet 1/2 (creates tagegd vlan port to access sw1)

description to Access Sw2

switchport

ipv6 address 2001:db8:1000:8000::1/64

no shutdown

exit

ipv6 route ::  2001:db8:1000:8000::2 (makes default router to next hop router)
