Secure Neighbor Discovery Configuration Overview
The Secure Neighbor Discovery (SEND) Protocol provides support for protecting Neighbor Discovery Protocol (NDP) messages. SEND is applicable in environments where physical security on a link is not ensured and attacks on NDP messages are a concern. The Junos® operating system (Junos OS) implementation secures NDP messages through cryptographically generated addresses (CGAs).
You must also enable IPv6 on at least one interface. Because SEND relies on dynamically generated CGAs, it does not support static IPv6 addresses.
