Syntax Description

[ default | 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 HA service is communicating with an FA service running in a
system. However, an HA service running in the system communicating with an FA 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 enabled.

Examples

The following command enables tunnel reassembly optimization:
optimize tunnel-reassembly
