Dear all,
    You know I am running Zebra-0.93b on a Linux machine. But there is a strange \
phenomenon when I am using OSPF6d routing:  Zebra can calculate the metric value for \
each OSPFv3 route correctly, which I can check from the "telnet localhost 2606" \
console. But after Zebra redistributes these OSPFv3 routes to Linux kernel, the \
metric is always set to 0. And Linux kernel displays as "1024" when I using "route -A \
inet6". But OSPFv2 has not this strange behavior.   And I checked the source code, in \
function "rib_add_ipv6()" of file "./zebra/rib.c", I found the metric value is always \
to 0, when Zebra redistributes IPv6 routes to Linux kernel (See function \
rib_process()). Is this behavor correct? How can I get the correct metric value of \
IPv6 routes in Linux kernel?  I will really appreciate if you can give me, a layman \
to Zebra, some help. :-)  Thanks,
