Dear FLProfessional, After I did some research the last couple of days, I noticed that I might have asked the wrong question. MIB II does not keep a routing table, let alone one that is different from the IP Routing table. The table can be accessed through some MIB II APIs, like the one I mentioned in the original post, m2IpRouteTblEntryGet() which is specific to VxWorks operating system. Today I learned of the kernel function ipcom_sysctl() which can get me the whole Routing Table, again it is a VxWorks kernel function. I guess each kernel has its own set of functions to access the RT. ??????!!!!!

Being a high level socket C/C++ programmer, I was searching for functions that would allow me to ask questions like "What entry in the Routing Table should I use to get to host 1.2.3.4"? or something similar.!!!!!!!
