What is a function of IPv6 Source Guard?
A. It works with address glean or ND to find existing addresses.
B. It inspects ND and DHCP packets to build an address binding table.
C. It denies traffic from known sources and allocated addresses.
D. It notifies the ND protocol to inform hosts if the traffic is denied by it.
Correct Answer: A
Explanation/Reference:
IPv6 source guard is an interface feature between the populated binding table and data traffic filtering. This feature enables the device to deny traffic when it is originated from an address that is not stored in the binding table. IPv6 source guard does not inspect ND or DHCP packets;rather, it works in conjunction with IPv6 neighbor discovery (ND) inspection or IPv6 address glean, both of which detect existing addresses on the link and store them into the binding table.
