IPv6 RA Proxy

An IPv6 network deployment typically has one or more upstream routers to delegate IPv6 prefixes throughRA路由器乱发广告tisement. 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.to clients. When a client connects to the network, it would begin with sending Router Solicitations orDHCPDynamic Host Configuration Protocol. A network protocol that enables a server to automatically assign an IP address to an IP-enabled device from a defined range of numbers configured for a given network.IPv6 requests. In case ofSLAACStateless Address Autoconfiguration. SLAAC provides the ability to address a host based on a network prefix that is advertised from a local network router through router advertisements.usingRA路由器乱发广告tisement. 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.where clients sends Router Solicitations, upstream routers can either respond with unicast (L2 or L3)RA路由器乱发广告tisement. 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.or with multicastRA路由器乱发广告tisement. 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.. Whenever a new client joins the network, a unicast or a multicastRA路由器乱发广告tisement. 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.is sent to from the router to the client. If it is a multicast packet then existing clients also receive theRA路由器乱发广告tisement. 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., which results in increasing the traffic. Starting fromArubaOS8.1, this issue is addressed by enabling IPv6 proxyRA路由器乱发广告tisement. 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.to snoop incoming unsolicitedRA路由器乱发广告tisement. 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.and Router Solicitations packets.

The following procedure describes how to configure IPv6RA路由器乱发广告tisement. 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.proxy settings:

1.In theManaged Networknode hierarchy, navigate to theConfiguration > Services >Firewalltab.

2.Expand theGlobal Settingsaccordion.

3.SelectIPV6 Proxy RAcheck box.

4.ClickSubmit.

5.ClickPending Changes.

6.In thePending Changeswindow, select the check box and clickDeploy changes.

Execute the following command to configure an interval for proxyRA路由器乱发广告tisement. 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.:

(host) [md] (config) #ipv6 proxy-ra interval

Execute the following command to enable the proxyRA路由器乱发广告tisement. 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.:

(host) [md] (config) #ipv6 proxy-ra

Execute the following command to view the status of the IPv6 proxyRA路由器乱发广告tisement. 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.:

(host) #show ipv6 ra proxy

IPv6 RA代理状态:启用
