On affected platforms running Arista EOS with IPsec AutoVPN Feature configured with dynamic paths, the configured IPsec replay window may not be applied as expected. As a result, IPsec anti-replay protection may be silently inactive even when it has been configured via an SA policy, contrary to the operator's expectation. This issue does not allow decryption of the affected IPsec traffic, but it may allow replay of previously valid protected traffic.
