26.11 IPv6 Source Guard Overview
The purpose of IPv6 source guard is to distinguish between authorized and unauthorized users by using a
binding table that validates the source of IPv6 traffic. The binding table can be manually created or be
learned through Dynamic Host Configuration Protocol version 6 snooping (DHCPv6 snooping). IPv6
source guard can deny IPv6 traffic from an unknown source. The IPv6 source guard binding table
includes:
• IPv6 address
• IPv6 prefix
