Neighbor Discovery makes abundant use of messages

False

____ uses ICMPv6 type 136 messages.

Neighbor Advertisement

____ uses ICMPv6 type 135 messages.

Neighbor Solicitation

A node invokes the ____ process when it wants to send a packet to an on-link neighbor but the sender does not know the link-layer address for the target node.

Address Resolution

The ____ option, if included, is used in Mobile IPv6 by mobile nodes receiving Router Advertisement messages for their movement detection algorithm.

Advertisement Interval

The IPv6 Neighbor Discovery (ND) protocol is specified in RFC 4861 and RFC ____.

5942

IPv6 Neighbor Solicitation protocol can be compared with IPv4 ____.

ARP Request

IPv6 Duplicate Address Detection protocol can be compared with IPv4

Gratuitous ARP

The ____ option is sent in Router Advertisement messages to provide a common MTU value for nodes on the same network segment.

MTU

Neighbor Discovery performs many of the functions that ICMP Router Discovery and ICMP ____ handled in IPv4.

Redirect

____ use ICMPv6 type 137 messages.

Redirect

____ help keep local routing optimized in the face of changing conditions and also reflect status as various destinations come on- and off-link.

Redirects

In the ICMPv6 Router Solicitation message, the ____ field is an unused field that is set to 0 by the source node and ignored by the destination node.

Reserved

IPv6 Router Advertisement protocol can be compared with IPv4

Router Advertisement

Routers periodically send ____ messages to inform hosts of link prefixes (if address autoconfiguration is enabled), link MTU, valid and preferred lifetimes, and other possible options.

Router Advertisement

The Target Link-Layer Address option is used in Neighbor Advertisement and ____ messages

Router Advertisement

____ uses ICMPv6 type 134 messages.

Router Advertisement

____ is used by nodes to discover neighbor routers on the local link, learn prefixes, configure their default gateway, and other possible configuration parameters relating to autoconfiguration (stateless or stateful) useful to the node.

Router Discovery

By default, IPv6 nodes will send a ____ multicast request for configuration parameters immediately upon start-up

Router Solicitation

____ uses ICMPv6 type 133 messages.

Router Solicitation

Home Agents may include the Home Agent Information option in their Router Advertisement messages, but it should not be included if the Home Agent (H) bit is not set.

True

ND takes over the functions that ARP and Reverse ARP handled in IPv4.

True

Neighbor Discovery has five functional processes.

True

ND makes use of multicast addresses, such as the "____" address with link-local scope (FF02::1)

all nodes

ND makes use of multicast addresses, such as the "____" address with link-local scope (FF02::2)

all routers
