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 up to 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 at least one tunnel endpoint exists, there would be 12 bytes to represent the information related to one tunnel endpoint.
