I have a site-to-site IPSEC VPN using 2 catalyst 6500's running IOS 12.2(18)SXD7b on each end.
After reviewing the syslog files this morning, I noticed that for the last 4 days at approximately the same time each nite, my router reports this error:
Local7.Warning: %CRYPTO-4-PKT_REPLAY_ERR: decrypt: replay check failed
The error reporting tool on cisco.com says this error is benign, but does not give much info or troubleshooting tips. I've double checked my configuration and everything looks fine. Have you guys seen this before? Any tips?
