Securing IPv6 address configuration

In a IPv6 domain, a node can obtain an IPv6 address using the following two mechanisms:

  • IPv6 address auto-configuration using router advertisements
  • DHCPv6 protocol

In a typical man-in-middle (MiM) attack, the attacker can spoof as a router with spurious router advertisements.To prevent such attacks, IPv6 RA guard helps to secure the IPv6 address configuration in the network.
