Cryptographic Authentication of OSPFv2 and OSPFv3

You can configure the authentication used for a specific routing protocol by specifying the key and cryptographic algorithm. This feature supports FIPS 140-2 Compliant Cryptographic Authentication for OSPFv2 and OSPFv3 using HMAC-SHA1, HMAC-SHA256, HMAC-SHA384 and HMAC-SHA512.

In addition, following features are supported.

• Protection against replay attack on routing Protocols.
• Protection against routing tables update by unauthorized peer for OSPFv2 and OSPFv3.
• Key rollover without bringing down the adjacency.
• Global configuration of keys and other relevant parameters.
