For use with either ESP or AH, a truncated value using the first 96 bits MUST be supported. Upon sending, the truncated value is stored within the authenticator field. Within the solid circles in Figure 13-7, esp-3des defines the encryption algorithm, while esp-sha-hmac defines the authentication algorithm. These parameters must be the same for both peers.

That's the purpose of HMAC (with either hash algorithm) in IpSec: It makes it possible to check if the content has been altered during transmission. While raw SHA1 is not as secure as it was thought to be, the known problems don't apply to HMACs with SHA1. Produces performance and encryption strength similar to SHA-1. HMAC - Hash-based Message Authentication Code is used to verify both the integrity and authenticity of a message.
