19.2.10 ipv6 proxy enable
Command:
ipv6 proxy enable
no ipv6 proxy enable
Function:
This command enable the IPv6 proxy function of a chassis switch. The no operation of this
command will disable IPv6 proxy function.
Command Mode:
Global Configuration Mode.
Default:
The IPv6 proxy function in the system is disabled by default.
Usage Guide:
IPv6 proxy function means that, the board cards supporting IPV4 only will forward the IPv6 packets
to the IPV6-supporting board cards in the system, implementing a process of wire-speed forwarding.
The proxy provided by IPv6 board cards indirectly realizes the Ipv6 hardware routing and forwarding
function implemented by earlier board cards which only support IPv4.
Notice:
If the IPv6 proxy function is enabled, at least one board cards supporting IPv6 hardware forwarding
should be plugged into the chassis switch. If all board cards in the chassis switch support IPv6
hardware forwarding, there would be no need to use the IPv6 proxy function. At present, the IPv6
proxy function does not support the proxy forwarding of IPv6 tunnel messages and multicast data
messages.
Examples:
Enable the IPv6 proxy function.
Switch(config)#ipv6 proxy enable
