Cisco Packet Tracer - Link Local Lan, Global Link Configuration Flashcards
What is a link-local address in IPv6?
A link-local address is an address that is valid only within the local network segment and is not routable beyond that segment.
True or False: Link-local addresses in IPv6 are automatically configured.
True
What is the typical format of a link-local IPv6 address?
The typical format is FE80::/10.
Fill in the blank: To configure a link-local address on a Cisco router, use the command ___ in interface configuration mode.
ipv6 address FE80::1 link-local
What command is used to enable IPv6 routing on a Cisco router?
ipv6 unicast-routing
Which command do you use to verify IPv6 interface configuration?
show ipv6 interface
Multiple Choice: Which command is used to set a global unicast IPv6 address on an interface? A) ipv6 address A) ipv6 address B) ipv6 link-local C) ipv6 enable D) ipv6 unicast
A) ipv6 address
What is the purpose of a global unicast address in IPv6?
Global unicast addresses are routable on the internet and can be used to identify devices across different networks.
True or False: A global unicast address always starts with 2000::/3.
True
Fill in the blank: To configure a global unicast address, you must specify the address and the prefix length using the format ___ in interface configuration mode.
ipv6 address <IPv6> <prefix></prefix></IPv6>
What is the significance of the prefix length in IPv6 addressing?
The prefix length indicates how many bits are used for the network portion of the address.
Which command can be used to check the routing table for IPv6?
show ipv6 route
What is the command to configure an interface to use a link-local IPv6 address?
ipv6 address FE80::1 link-local
Multiple Choice: Which command is NOT used for IPv6 configuration? A) ipv6 address B) ipv6 enable C) ipv6 link-local D) ipv6 routing
D) ipv6 routing
True or False: Link-local addresses can be used to communicate with devices on other networks.
False
What command would you use to enter interface configuration mode for GigabitEthernet 0/0?
interface GigabitEthernet 0/0
Fill in the blank: The command to enable IPv6 on an interface is ___ in interface configuration mode.
ipv6 enable
What is the key difference between link-local and global unicast addresses?
Link-local addresses are not routable and are used within a local network, while global unicast addresses are routable and used for communication across the internet.
What command is used to display the IPv6 address configuration on all interfaces?
show ipv6 interface brief
True or False: Each IPv6 interface must have at least one link-local address.
True
Multiple Choice: What is the default prefix length for a global unicast address? A) /64 B) /48 C) /32 D) /128
A) /64

ipv6 route <destination> <prefix> <next-hop></next-hop></prefix></destination>
What is the command to enable IPv6 on a Cisco switch?
ipv6 unicast-routing
True or False: IPv6 link-local addresses can be used for communication between devices on the same local network.
True
What is the command to verify the status of IPv6 on an interface?
show ipv6 interface <interface></interface>
Multiple Choice: What is the maximum size of an IPv6 address? A) 32 bits B) 64 bits C) 128 bits D) 256 bits
C) 128 bits

ipv6 address <global>/<prefix></prefix></global>
What command is used to configure a default IPv6 route?
ipv6 route ::/0 <next-hop></next-hop>
True or False: You can have multiple link-local addresses on a single interface.
False
What is the command to enable IPv6 on a specific interface?
ipv6 enable

Fill in the blank: In Cisco Packet Tracer, you can create a link-local LAN by configuring an interface with the command ___ followed by a link-local address.
ipv6 address
What does the prefix length of /64 indicate in IPv6 addressing?
It indicates that the first 64 bits of the address are used for the network portion.
True or False: Global unicast addresses can be used for local communication only.
False
