使用IPv6拉

ArubaOSenables themanaged deviceto send RA in an IPv6 network. Each host auto generates a link local address when you enable ipv6 on the host. The link local address allows the host to communicate between the nodes attached to the same link.

The IPv6 stateless autoconfiguration mechanism allows the host to generate its own addresses using a combination of locally available information and information advertised by the routers. The host sends a router solicitation multicast request for its configuration parameters in the IPv6 network. The source address of the router solicitation request can be an IP address assigned to the sending interface, or an unspecified address if no address is assigned to the sending interface.

The routers in the network respond with an RA. The RAs can also be sent at periodic intervals. The RA contains the network part of the Layer 3 IPv6 address (IPv6 Prefix). The host uses the IPv6 prefix provided by the RA; it generates the universally unique host part of the address (interface identifier), and combines the two to derive the complete address. To establish continuous connectivity to the default router, the host starts the neighbor reachability state machine for the router.

ArubaOSuses Radvd, an open source Linux IPv6RARouter Advertisement. The RA messages are sent by the routers in the network when the hosts send multicast router solicitation to the multicast address of all routers.daemon maintained by Litech Systems Design.

You can perform the following tasks on themanaged deviceto enable, configure, and view the IPv6 RA status on a VLAN interface:

Configure IPv6 RA on a VLAN

Configure Optional Parameters for RA

Configure neighbor discovery reachable time

Configure neighbor discovery retransmit time

Configure RA DNS

Configure RA hop-limit

Configure RA interval

Configure RA lifetime

Configure RA managed configuration flag

Configure RA MTU

Configure RA other configuration flag

Configure RA Preference

Configure RA prefix
