Ans. Differences between Stateless and Stateful Stateless Stateful 1:1 translation 1:N translation No conservation of IPv4 address Conserves IPv4 address Assures end-to-end address Uses address overloading, hence lacks in transparency and scalability end-to-end address transparency No state or bindings created on the State or bindings are created on every translation unique translation Requires IPv4-translatable IPv6 No requirement on the nature of IPv6 addresses assignment (mandatory address assignment requirement) Requires either manual or DHCPv6 Free to choose any mode of IPv6 address based address assignment for IPv6 assignment viz. Manual, DHCPv6, hosts SLAAC (b) Gives the Configuration commands in OSPFv3. Ans. The commands required to configure OSPFv3 on a network device. Enter global configuration mode router#configure terminal 1 Enable device IPv6 unicast forwarding router(config)#ipv6 unicast-routing 2 Enter interface configuration mode router(config)#interface interface 3 Enable OSPFv3 on the interfaceNote: In newer router(config-if)#ipv6 ospf process-id area 4 versions of IOS 15 this command is being changed, the newer version of the command will be ospfv3 process-id area. Repeat steps 1-4 on all OSPFv3 interfaces Enter OSPFv3 router configuration modeNote: router(config-if)#ipv6 router ospf process-id 5 This is a global configuration mode command Configure the router-ID to be used by router(config-router)#router-id ip-address 6 OSPFv3Note: This is required if no IPv4 address is assigned on the device. Q5 Compare IPv4 multicasting & IPv6 multicasting.
