A version of IOS with the IPv6 support is necessary for the following orders.
This example requires the presence of an interface LAN named ethernet0.
Note: the order "ipv6 unicast-routing" became necessary if you want to make routing (RA will not function without this)
Cisco IOS 12.2(2)T
configure terminal

The configuration by defect of routers Cisco under the IOS in IPv6 includes/understands
a limitation of sendings ICMP. It is a little the equivalent of ICMP_BANDLIM under FreeBSD,
except that the adjustment by defect is too important.
That causes of step badly "to rot" the ' traceroute' that one carries out on the IPv6
network as soon as there is a router Cisco.
To be quiet, apply the following order in total configuration :
routeur(config)#ipv6 icmp error-interval 0
Thanks to Raphael Bouaziz (Nerim).
