The value of vRtrInetCidrRouteTunnEndpntInfo indicates tunnel endpoint
information. The first 4 bytes indicate number of tunnel end-points,
the next 4 bytes indicate IGP cost to reach tunnel end-points and the
next 64 bytes indicate upto 16 4-byte IPv4 addresses (the number of
end-points represented by bytes 1-4 indicate how many addresses are
present). When no tunnel endpoints exist, the size of this object
will be 0. When atleast one tunnel-endpoint exists, there would be
12 bytes to represent the information related to one tunnel endpoint.
