Command
ipv6 unreachables
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
ipv6 traffic-filter WORD { in |
out }
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
ipv6 cur-hoplimit value
