Greetings,

This draft was mentioned in the IPSECME session today. It describes a strategy for safely sharing an IPsec SA between multiple senders when the SA includes a block cipher counter mode. It has been suggested that strategy may be useful for cluster members sharing this kind of SA. The draft has officially ended IETF last call, but timely comments are still welcome.

Thanks,
Brian
