Enabling IPv6 routing
1. On each VLAN, configure stateless address autoconfiguration and at least one IPv6 global
unicast address:
vlan n ipv6 address autoconfig
vlan n ipv6 address prefix/prefix-length eui-64
These commands result in a link-local address and a global unicast address having an interface
ID derived from the routing switch's MAC address. For more information on this topic, or to
manually configure link-local and global unicast addressing with a non-EUI interface ID, see
“Statically configuring a link-local unicast address” (page 18).
2. Suppress automatic (default) RAs on VLAN interfaces where you need to make configuration
changes or where you do not currently want these advertisements generated:
• To globally suppress RAs on the routing switch, use this command in the global config
context:
ipv6 nd suppress-ra
• To suppress RAs on individual VLANs, use this command in the context of each VLAN
where you want the advertisements suppressed:
ipv6 nd ra suppress
The no form of the above two suppress commands disables RA suppression. For more
information on RAs, see “IPv6 Router Advertisements” (page 186).
