LCOS as of version 10.30 supports IKEv2 fragmentation according to RFC 7383. This enables the VPN router to fragment IKEv2 messages by itself, which is more efficient than having IKE-packet fragmentation performed by the transport network. Two methods of IKEv2 fragmentation are supported:
- Manufacturer-specific fragmentation, compatible with third-party manufacturers
- Fragmentation as per RFC 7383
Note: The device sets the best method automatically. If a VPN remote site supports both methods, fragmentation as per RFC 7383 is preferred.
