JUEX-RT-001000 - The Juniper router must not be configured to use IPv6 Site Local Unicast addresses.
Information
As currently defined, site local addresses are ambiguous and can be present in multiple sites. The address itself does not contain any indication of the site to which it belongs. The use of site-local addresses has the potential to adversely affect network security through leaks, ambiguity, and potential misrouting as documented in section 2 of RFC3879. RFC3879 formally deprecates the IPv6 site-local unicast prefix FEC0::/10 as defined in RFC3513.Solution
Configure the router using authorized IPv6 addresses.Delete unauthorized addresses:
delete interfaces <interface name> unit <logical unit number> family inet6 address <unauth address>/<prefix>
Configure authorized addresses:
set interfaces <interface name> unit <logical unit number> family inet6 address <auth address>/<prefix>
