When a packet is nearly the size of the maximum transmission unit (MTU) of the physical egress port of the encrypting switch, and it is encapsulated with IPsec headers, it probably will exceed the MTU of the egress port. Fragmentation in Different Modes Overview of Fragmentation and MTU.This section includes the following topics: Understanding IPsec VPN Fragmentation and MTU In these instances, the VSPA performs the equivalent function. Note Some illustrations in this chapter refer to the IPsec VPN SPA. For more information about accessing these publications, see the "Related Documentation" section.
