Config Cisco Nexus L3 vlan routing IPv6
Config Cisco Nexus L3 vlan routing IPv6
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)

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