+Subject: [PATCH] radvdump: show routes with prefixlen > 64
+
+Current radvdump code blindly copies over eight bytes of route prefix
+but its size in bytes can actually be zero, eight or sixteen.
+
+Use the following `/etc/radvd.conf` to reproduce:
+
+ interface eth0 {
+ AdvSendAdvert on;
+ MinRtrAdvInterval 3;
+ MaxRtrAdvInterval 4;
+ route 2001:db8:0:0:11::/80 {};
+ };
+
+Output before the change:
+
+ route 2001:db8::/80
+ {
+ AdvRoutePreference medium;
+ AdvRouteLifetime 12;
+ }; # End of route definition
+
+Output after the change:
+
+ route 2001:db8:0:0:11::/80
+ {
+ AdvRoutePreference medium;
+ AdvRouteLifetime 12;
+ }; # End of route definition
+
