Add support for pref64 option, as defined in RFC8781. The prefix valid lifetime
must not be smaller than the "interface interval max" definition which defaults
to 600.
set service router-advert interface eth1 nat64prefix 64:ff9b::/96
(cherry picked from commit f1ead5c6a16aba00699b8a5b9c18ef6cffe8cc4d)

Commit 13071a4a ("T4809: radvd: Allow the use of AdvRASrcAddress") added a new
feature to set the RA source-address. Unfortunately it missed a semicolon.
|
|
This add the AdvRASrcAddress configuration option to configure
a source address for the router advertisements. The source
address still must be configured on the system. This is useful
for VRRP setups where you want fe80::1 on the VRRP interface
for cleaner VRRP failovers.

DeprecatePrefix and DecrementLifetimes options in radvd is useful in a DHCPv6-PD environment to accommodate prefix changes from ISP's delegating router. Though there is currently no integration between the DHCP PD client (wide-dhcpv6-client) and radvd, it could be a good start point to have the 2 options configurable by the user.

- deprecate-prefix: Upon shutdown, deprecate the prefix. This is useful
in a DHCPv6 PD environment: When ISP re-assigns a new prefix,
deprecate the old prefix that was advertised.
- decrement-lifetimes: Decrement the values of the preferred and valid
lifetimes for the prefix over time. This is also useful in a DHCPv6
PD environment to keep the advertised prefix's lifetimes in sync with
the prefix from delegating router.
