Syntax Description

[ no ] optimize tunnel-reassembly

Usage Guidelines

Enabling this functionality fragments large packets prior to encapsulation for easier processing. Tunnel
reassembly optimization is disabled by default.

You should not use this command without first consulting Cisco Systems Technical Support. This command
applies to very specific scenarios where packet reassembly is not supported at the far end of the tunnel.
There are cases where the destination network may either discard the data, or be unable to reassemble the
packets.

Important

This functionality works best when the FA service is communicating with an HA service running in a
system. However, an FA service running in the system communicating with an HA from a different
manufacturer will operate correctly even if this parameter is enabled.

Important

Use the no version of this command to disable tunnel optimization if it was previously enabled.

Examples

The following command enables tunnel reassembly optimization:
