User Guidelines
In general, an IPv6 ICMP redirect is sent if:
• The packet is not addressed to the router.
• The packet will be forwarded over the interface on which it was received.
• The router determines that a better first-hop resides on the same VLAN as
the source of the packet.
• The source address of the received packet is a link-local or global IPv6
address of a neighbor on the VLAN.
• Using the no form of the command to disable IPv6 ICMP redirects.
Command History
Command introduced in version 6.5 firmware.
Example
This example disables sending of IPv6 ICMP redirects on VLAN 6.
console(config-if-vlan6)# no ipv6 redirects
ipv6 route
Use the ipv6 route command to configure an IPv6 static route. Use the no
form of the command to remove a preference, an individual next hop, or all
next hops for a route. Using the no ipv6 route distance form causes the
system to use the system default administrative distance.
Syntax
ipv6 route ipv6-prefix/prefix-length {next-hop-address | Null0 | vlan vlan-id
| tunnel tunnel-id} [preference] [track <object-number>]
