Description

Radvd functions properly when LAN interface is set as tracking to WAN and WAN is set to DHCP6 with a prefix delegation size is 64. When the prefix delegation size is set to a value such as 62 or 60 radvd is completely missing from the status->services page. Additionally, the only IPv6 address present on the LAN interface is fe80::1:1. Toggling "Send IPv6 prefix hint" (plus saving and applying) has no impact on the absence of radvd. I verified my findings on a clean 2.1 i386 instal with a stock configuration with no changes other than those which pertain to IPv6 on the WAN interface. Restarting the box after changing the prefix delegation to 60 changes nothing. Changing the prefix delegation back to 64 restores radvd and IPv6 connectivity on the LAN interface, even without restarting the box. My ISP is Comcast and /60 delegations are available in my area, verified by a Cisco 1841 router.
