radvd and dhcpv6 dows not agree on the prefixes
Last modified: 2007-11-30 17:10:58 EST
Description of problem: (Just copying from the link) "I manage to get the prefix for the client router which i saw from the debug message, but I didn"t see any modification done to /etc/radvd.conf by the dhcp6c program. I suppose it should modify the range of the available IP addresses according to the assigned prefix." Version-Release number of selected component (if applicable): dhcpv6-0.10-9 How reproducible: Always Steps to Reproduce: 1. Set up dhcpv6 with correct prefix 2. restart dhcpv6 (server) and radvd 3. start dhcp6c on a client to get address Actual results: radvd will give you different prefixes than dhcp6 Expected results: radvd and dhcp6 should agree on what to give the clients Additional info: There is also a patch provided on the url mentioned: in line 116 of radvd_token.l, (before) : if (!strcmp(yytext, dhcp6_if->ifname)) (after) : if (strcmp(yytext, dhcp6_if->ifname))
This is now fixed, in version dhcpv6_client-0.10-10 . Only if radvd.conf already contains an interface ethX { ... } ; definition, and dhcp6c gets a prefix lease, then dhcp6c will write the 'prefix' statement to the existing interface definition, such as: interface eth0 { # update prefix from DHCPv6 server prefix fec0:0:0:1::/64 {}; }; and will restart radvd IF it is already running . dhcpv6-0.10-10 will be in tomorrow's FC4/rawhide release .
