IPsec compression reduces the size of the IP datagram to improve the communication performance between hosts connected behind Backbone Edge Bridges (BEB).
Note
This feature is supported on 5720-24MXW and 5720-48MXW using Fabric IPsec Gateway.
Tip
As a best practice, use IPsec compression only for Fabric Extend tunnels where latency is greater than 70ms.
The following list identifies how you can implement IPsec compression:
You can configure multiple IPsec Fabric Extend (FE) adjacencies with or without compression simultaneously.
You must enable IPsec compression on both BEBs to use IPsec compression for an FE adjacency.
You cannot configure IPsec compression if fragmentation before encryption is already enabled.
You can change the IPsec compression configuration only if IPsec is disabled.
To configure IPsec compression, see Configure IPsec Compression.
