•
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,
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.
•
This command 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.
