I also found the same netmask problem in the route deletion method (_netsnmp_ioctl_route_delete_v4) which is in the same source file (route_ioctl.c). However, route deletion only works after a restart of snmpd, and crashes snmpd if a route was previously added during the same runtime instance. I think this issue lies with route caching, but I have not looked much into it.

I did create a function for converting prefix to mask, and it should be fixed the the next 5.7.3.pre release. /Niels -- Niels Baggesen - @home - Århus - Denmark - n...@users.sourceforge.net The purpose of computing is insight, not numbers --- R W Hamming
