Hi Ben, all, 

Glad to see that you found the text where explain why MD5 is supported in the model. 

Added this NEW text to the security considerations section: 

   As discussed in Section 7.6.3, the module supports MD5 to basically
   accommodate the installed BGP base.  MD5 suffers from the
   security weaknesses discussed in Section 2 of [RFC6151] or
   Section 2.1 of [RFC6952].

Cheers,
Med
