FYI, the prefix length can be accessed by entry->rt_pfx_len in this method (_netsnmp_ioctl_route_set_v4). I wrote a little code to convert entry->rt_pfx_len (the prefix length) to a netmask (unsigned int) and tried it out. Adding new routes via inetCidrRouteTable seems to work now. If anyone's interested, I could provide a patch.

So I am using inetCidrRouteTable. Unfortunately, the implementation of _netsnmp_ioctl_route_set_v4() in route_ioctl.c always hardcodes the route's netmask to 0.0.0.0, allowing only default gateway routes to be added. I had to manually change the following line: mask.sin_addr.s_addr = htonl(0); to: mask.sin_addr.s_addr = htonl(0xffff0000); for the following snmpset command to work: snmpset -l authPriv -A password -X password -a SHA -x AES -u authPrivUser localhost IP-FORWARD-MIB::inetCidrRouteStatus.1.4.20.20.0.0.16.2.0.0.1.4.10.10.0.1 i 4 IP-FORWARD-MIB::inetCidrRouteIfIndex.1.4.20.20.0.0.16.2.0.0.1.4.10.10.0.1 i 3 IP-FORWARD-MIB::inetCidrRouteMetric1.1.4.20.20.0.0.16.2.0.0.1.4.10.10.0.1 i 0 IP-FORWARD-MIB::inetCidrRouteType.1.4.20.20.0.0.16.2.0.0.1.4.10.10.0.1 i 4 I want to do the equivalent of: ip route add 20.20.0.0/16 via 10.10.0.1 I am new to SNMP and so I could be doing this wrong or making incorrect assumptions. Perhaps there is an alternative method to adding static routes that are not default gateways? Or is this simply a bug?
