SD-WAN

Cisco, although not explicitly stating it in a direct way, “recommends” for OSPF authentication the use of RFC 5709, which supports HMAC-SHA cryptographic authentication, instead of RFC 2328 Message-Digest 5 (MD5).

Today all boxes has some kind of firewall deamon running, providing certain set of security future. What if such feature can t be switched off and SD-WAN service provider has built up solution with Versa box?
