E. SNMP MIB Objects

IP Group – “ipRouteDest” Object (ipRouteEntry 1)

The ipRouteDest object serves as the index to the routing table. Since indexes for tables must be unique, only one route per destination may appear in the table. To ensure that no duplicate destinations appear in the routing table, the ipRouteDest object of the ipRouteTable will be treated as described in RFC 1354 (IP Forwarding Table MIB):

“The destination IP address of this route. An entry with a value of 0.0.0.0 is considered a default route. This object may not take a Multicast (Class D) address value. Any assignment (implicit or otherwise) of an instance of this object to a value x must be rejected if the bitwise logical – AND of x with the value of the corresponding instance of the ipForwardMask object is not equal to x.”

IP Group – “ipRouteIfIndex” Object (ipRouteEntry 1)

When the routing table is displayed, the ipRouteIfIndex object for some entries may have a value greater than ifNumber. In these cases, the ipRouteIfIndex refers to a proprietary interface which is not currently implemented by the interface group of MIB II. Route entries with an unrecognized ipRouteIfIndex value should not be deleted.

When setting this object via SNMP, the ipRouteIfIndex value can only assume an appropriate value of ifIndex defined for the particular device type.

IP Group – “ipRouteMetric2” Object (ipRouteEntry 4)

The following values are displayed for the ipRouteMetric2 object. For a carrier device designated as the IP Bus Master, ipRouteMetric2 is used to designate the slot number of the next hop associated with this route if the destination is not connected to the device. For carrier devices not designated as the IP Bus Master or IP Bus Master devices in which the destination is connected to the device, ipRouteMetric2 contains the slot number (0-15) of the carrier device. For standalone devices, ipRouteMetric2 is not used and contains –1.

When adding a route to the routing table using SNMP, do not specify a value for ipRouteMetric2.

IP Group – “ipRouteProto” Object (ipRouteEntry 9)

his object is a read-only object and may have the following values in the DSU/CSU.

other(1) – Temporary route added by IP.

local(2) – Route added or modified as a result of user configuration via the front panel.

netmgmt(3) – Route added or modified by means of an SNMP set.

icmp(4) – Route added or modified by Internet Control Management Protocol

T(ICMP).

rip(8) – Route added or modified by Routing Information Protocol (RIP) (or similar proprietary protocol).
