Chapter 77 Setting the IPv6 Services
77.1 Setting the IPv6 Services
After IPv6 is enabled, all services provided by IPv6 can be set. The configurable IPv6 service is shown below:
(1) Managing the IPv6 Link
77.1.1 Managing the IPv6 Link
IPv6 provides a series of services to control and manage the IPv6 link. This series of services includes:
(1) Setting the transmission frequency of the ICMPv6 packet
(2) Setting the source IPv6 route
(3) Setting the MTU of IPv6
(4) Setting IPv6 redirection
(5) Setting IPv6 destination unreachablity
(6) Setting IPv6 ACL
(7) Setting IPv6 Hop-Limit
Setting the transmission frequency of the ICMPv6 packet
If you want to limit the transmission frequency of the ICMPv6 packet, run the command in the following
table. If the ICMPv6 transmission frequency is larger than the set value, the transmission frequency will
be limited.
The default transmission frequency is 1000us. If you want to modify the transmission frequency, run the
following command in global mode:
Command Purpose
ipv6 icmp6-ratelimit ratelimit Sets the transmission frequency of the
ICMPv6 packet.
Setting the source IPv6 route
IPv6 allows a host to designate the route of an IPv6 network, that is, the source route. The host can realize
the source route through using the routing header in the IPv6 packets. The router can forward packets
according to the routing header, or desert this kind of packets considering security.
The router supports the source route by default. If the source route is closed, users can run the following
command in global configuration mode to open the source route.
Command Purpose
ipv6 source-route Allows the source IPv6 route.
Setting the MTU of IPv6
