4.3.2.3 RA-Guard
Route Management > IPv6 Interface Configuration > RA-Guard page is used to configure RA guard status on a port or group.
◆Interface – Shows port or trunk configuration page.
◆RA Guard – Blocks incoming Router Advertisement and Router Redirect packets. (Default: Disabled)
IPv6 Router Advertisements (RA) convey information that enables nodes to auto-configure on the network. This information
may include the default router address taken from the observed source address of the RA message, as well as on-link prefix
information. However, note that unintended misconfigurations, or possibly malicious attacks on the network, may lead to bogus
RAs being sent, which in turn can cause operational problems for hosts on the network.
RA Guard can be used to block RAs and Router Redirect (RR) messages on the specified interface. Determine which interfaces
are connected to known routers, and enable RA Guard on all other untrusted interfaces.
