Neighbor Solicitation
A host invoking the Duplicate Address Detection process sends what type of message?
link-local
A nodes prefix list uses an infinite (indefinite) invalidation timer for which type of entry?
Gratuitous ARP (Address Resolution Protocol) GARP
An ICMPv6 Duplicate Address Duplication (DAD) message is closely related to which ICMP message?
When set to 1, hosts must use an address configuration protocol such as DHCPv6 to obtain address configuration information.
How does a host interpret the Managed Address Configuration (MAC) flag in a Router Advertisement message?
An initial sending of three packets, then at random intervals.
How frequently do routers send unsolicited Router Advertisement messages?
icmpv6.type == 136
If using Wireshark to analyze a large packet capture from the network, which filter would be configured to display only packets that are Neighbor Advertisement messages?
Prefix and Prefix Length
In Router Advertisement message, which two combined Prefix Information options comprise the IPv6 prefix address?
FF02::1
The link-local scope all-nodes multicast address is which of the following?
FF02::2
The link-local scope all-routers multicast address is which of the following?
When set to 1, the host should use the prefix received for on-link address determination.
Upon receipt of the L flag in the Prefix Options of the Router Advertisement message, how should the host respond?
When set to 1, hosts may use an address configuration protocol such as DHCPv6 to obtain non-address configuration information.
Upon receipt of the Other Configuration flag in a Router Advertisement message, how should the host respond?
INCOMPLETE, REACHABLE, STALE, DELAY, PROBE
What are the five states of a neighbor cache entry? HINT: (IRSDP)
when its own link-layer address changes
What is one possible condition upon which a node will send an unsolicited Neighbor Advertisement message.
unicast
What type of packet is a node sending to another node that is on-link?
multicast
What type of packet is a node sending when it sends a Neighbor Solicitation message for the address resolution?
unspecified address
When a node starts up and does not have an IPv6 address, it uses which address as its source address when sending a Router Solicitation message?
To inform the host that a better first-hop router is available.
When a router sends a Redirect message to a host, which of the following choices best represents the intent of such a message?
Redirect & Neighbor Solicitation
Which Neighbor Discovery messages will include the source link-layer address of the sender in its options field?
4861
Which RFC most completely defines Neighbor Discovery for IPv6?
Routers do not update their routing table if they receive Redirect messages. Hosts do not send Redirect messages.
Which are the basic rules of operations for nodes (routers and hosts) concerning Redirect messages?
When set to 1, the router is functioning as a Mobile IPv6 home agent.
Which choice best represents how a host should behave upon receipt of the H flag in the Prefix Options of the Router Advertisement message?
Router Solicitation - 133 Router Advertisement - 134
Which of the following ICMPv6 type numbers relate to Router Solicitation and Router Advertisement messages?
135
Which of the following ICMPv6 type numbers relates to Neighbor Solicitation messages?
-Solicited Neighbor Advertisements are received within the REACHABLE_TIME variable. -Upper-layer protocol indicates forward progress within the REACHABLE_TIME variable.
Which of the following choices permit a node to consider a neighbor to be reachable?
-Destination address is in the destination cache. -Link-layer entry is in the neighbor cache.
Which two conditions must be met in order for a host to send a packet to a destination node's link-layer address?
