![]() ![]() This table lists the IPsec configuration components and algorithms affected by this change: IPsec Configuration ![]() Otherwise, IPsec tunnel negotiation will fail and cause service disruption as a result. In order to continue to use such weak algorithms, explicit configuration is required. Cisco strongly recommends the use of stronger cryptographic algorithms in their place. In Cisco IOS XE Release 17.11.1 and later, weak crypto algorithms are no longer allowed by default due to their weak cryptographic properties. In releases earlier than Cisco IOS ® XE Release 17.11.1, weak crypto algorithms, including integrity, encryption, and Diffie-Hellman group algorithms, can be configured for IPsec protocol negotiation as well as data plane traffic protection. Router should not allow weak cryptographic algorithms to be configured for IPsec CISCO RESERVES THE RIGHT TO CHANGE OR UPDATE THIS FIELD NOTICE AT ANY TIME.
