FS#964 - odhcpdIPv6 node(Win 10) stops sending Router Solicitation but it still receives RAs from LEDE
User who did this - Hans Dedecker (dedeckeh)

----------
The RA transmission rate on the wan ppp interface is very chatty; it varies between 10 and 23 seconds... On top the router lifetime is set to 40 seconds resulting into a similar lifetime for the default IPv6 route.
The problem is not situated in the odhcpd daemon but in the odhcp6c DHCPv6 client daemon as it only accepts ra updates every 30 seconds. This will cause the default IPv6 route to time out resulting into the observed behavior.
Further investigation is required why this limitation has been put into place.
