To open IPv6 redirection, run the following command:
Command Purpose
ipv6 redirects Allows IPv6 to transmit the redirection packets.
5. Setting IPv6 destination unreachability
In many cases, the system will automatically transmit the destination-unreachable packets. Users can close
this function. If this function is closed, the system will not transmit the ICMP unreachable packets.
To enable this function, run the following command:
Command Purpose
ipv6 unreachables Allows IPv6 to transmit the destination unreachable
packets.
6. Setting IPv6 ACL
Users can use ACL to control the reception and transmission of packets on a VLAN interface. If you introduce
ACL on a VLAN interface in global configuration mode and designate the filtration's direction, the IPv6 packets
will be filtered on this VLAN interface.
To filter the IPv6 packets, run the following command in interface configuration mode.
Command Purpose
ipv6 traffic-filter WORD { in |
out }
Filters the IPv6 packets in the reception or transmission
direction (in: receive; out: transmit) on a VLAN interface.
7. Setting IPv6 Hop-Limit
Users can designate a router to transmit the value of the hop-limit field in the packets (except those forwarded
packets). All those packets that this router transmits out, if the upper-level application does not apparently
designate a hop-limit value, use the set value of hop-limit. At the same time, the value of the hop-limit field is
added to the RA packets that this router transmits.
The default hop-limit value is 64. If you want to change this value, you can run the following command in
interface configuration mode.
Command Purpose
ipv6 cur-hoplimit value
Designates a router to transmit the hop-limit field of the
packets.
