How do IPv6 enabled routers handle packet fragmentation?
- IPv6 routers do not perform packet fragmentation. OSPFv3 has a mechanism for determining the optimal packet size and dynamically adjusting the packet size.
- IPv6 routers do not perform packet fragmentation. CDP is used to discover the correct packet size for any given traffic flow. The correct packet size is unique for each traffic flow.
- IPv6 routers perform packet fragmentation. CDP is used to determine which packets need to be fragmented for any given traffic flow.
- IPv6 routers perform packet fragmentation. OSPFv3 has a mechanism for fragmenting packets so that they are the optimal size.
- IPv6 routers do not perform packet fragmentation. A discovery process is used to determine the optimum maximum transmission unit (MTU) to use during a given session.
- IPv6 routers perform packet fragmentation. IPv6 built-in QoS mechanisms automatically adjust the packet fragmentation for a given session.
