F. SNMP MIB Objects
3150-A2-GB24-10 March 2001
F-9
To add a route using an SNMP set, you must specify a group of minimal objects.
These variable bindings must be contained in a single Protocol Data Unit (PDU).
The objects are described in more detail in the following sections. The minimal set
consists of:
„
ipRouteDest
„
ipRouteIfIndex
The following objects are defaulted if not specified in the set PDU used to add a
route.
„
ipRouteMetric1 – Defaulted to 1 hop.
„
ipRouteMetric2 – Defaulted to current slot for carrier devices and –1 for
standalone devices.
„
ipRouteType – Defaulted to indirect.
„
ipRouteMask – Defaulted as specified in the MIB description.
The following objects are unused in the CSU and setting them will have no effect
on the operation of the IP implementation.
„
ipRouteMetric3, ipRouteMetric4, ipRouteMetric5 – Defaulted to –1 as
specified in the MIB.
„
ipRouteNextHop – Defaulted to 0.0.0.0.
The following read-only objects must not be specified in the set PDU used to add a
route.
„
ipRouteProto – Set to netmgmt(3) by software.
„
ipRouteAge – Defaulted to 999.
„
ipRouteInfo – Set to OBJECT IDENTIFIER {0, 0} since it is unused.
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 .”
