From 3253864641e797809a99401174688507a01c1255 Mon Sep 17 00:00:00 2001 From: Yuxiang Zhu Date: Thu, 21 Jul 2022 07:31:28 +0000 Subject: T4550: router-advert: Add deprecate-prefix & decrement-lifetimes options 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. https://phabricator.vyos.net/T4550 - 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. --- interface-definitions/service-router-advert.xml.in | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'interface-definitions') diff --git a/interface-definitions/service-router-advert.xml.in b/interface-definitions/service-router-advert.xml.in index 258b7b749..87ec512d6 100644 --- a/interface-definitions/service-router-advert.xml.in +++ b/interface-definitions/service-router-advert.xml.in @@ -249,6 +249,18 @@ + + + Upon shutdown, this option will deprecate the prefix by announcing it in the shutdown RA + + + + + + Lifetime is decremented by the number of seconds since the last RA - use in conjunction with a DHCPv6-PD prefix + + + Time in seconds that the prefix will remain preferred -- cgit v1.2.3
