Protocol
This object specifies the value of the protocolfield in
the ip header for all IP-datagrams belonging to the set.
If this object is set to dont-verify, the value of the
protocol field is not specified and can take any value.
Enumerations:
  • icmp (1)
  • ggp (3)
  • tcp (6)
  • egp (8)
  • pup (12)
  • udp (17)
  • hmp (20)

  • ospf (89)
  • l2tp (115)
  • dont-verify (256)
SrcIfIndex
This object specifies the source index of the IP-datagrams.
If this object has a value other than 0, only datagrams
received  over the interface with the appropriate interface
index are considered to be part of the set. If this object
is set to 0, the source interface index for the datagrams
belonging to the set is not specified.
SrcAddr
This object describes together with ipExtRtSrcMask the 
range of the source-addresses of the IP-datagrams belonging
to the set. If both objects are set to 0.0.0.0 the source-
addresses for the datagrams in the set is not specified
and can take any value.
SrcMask
This object describes together with ipExtRtSrcAddr the 
range of the source-addresses of the IP-datagrams belonging
to the set. If both objects are set to 0.0.0.0 the source-
addresses for the datagrams in the set is not specified
and can take any value.
SrcPort
This object describes together with ipExtRtSrcPortRange the
range of source portnumbers of the IP-datagrams belonging to
the set. All portnumbers between and including the two
objects are within the range.
If both objects are the to -1, the value of the source
portnumber is not specified and can take any value.
SrcPortRange
This object describes together with ipExtRtSrcPort the
range of source portnumbers of the IP-datagrams belonging to
the set. All portnumbers between and including the two
objects are within the range.
If both objects are the to -1, the value of the source
portnumber is not specified and can take any value.
DstAddr
This object describes together with ipExtRtDstMask the 
range of the target-addresses of the IP-datagrams belonging
to the set. If both objects are set to 0.0.0.0 the target-
addresses for the datagrams in the set is not specified
and can take any value.
DstMask
This object describes together with ipExtRtDstAddr the 
range of the target-addresses of the IP-datagrams belonging
to the set. If both objects are set to 0.0.0.0 the target-
addresses for the datagrams in the set is not specified
and can take any value.
DstPort
This object describes together with ipExtRtDstPortRange the
range of target-portnumbers of the IP-datagrams belonging to
the set. All portnumbers between and including the two
objects are within the range.
If both objects are the to -1, the value of the target
portnumber is not specified and can take any value.
DstPortRange
This object describes together with ipExtRtDstPort the
range of target-portnumbers of the IP-datagrams belonging to
the set. All portnumbers between and including the two
objects are within the range.
If both objects are the to -1, the value of the target
portnumber is not specified and can take any value.
Tos
This object describes together with ipExtRtTosMask the 
range of the Type of Service field (TOS) in the IP-header
of the IP-datagrams belonging to the set. A TOS value is
considered within the range, when the following equation
is valid:
(tos & ipExtRtTosMask) == (ipExtRtTos & ipExtRtTosMask)
If both objects are set to 0 the TOS value of the datagrams
in the set is not specified and can take any value.
TosMask
This object describes together with ipExtRtTos the 
range of the Type of Service field (TOS) in the IP-header
of the IP-datagrams belonging to the set. A TOS value is
considered within the range, when the following equation
is valid:
(tos & ipExtRtTosMask) == (ipExtRtTos & ipExtRtTosMask)
If both objects are set to 0 the TOS value of the datagrams
in the set is not specified and can take any value.
DstIfMode
This object describes different behavior depending on the
ifOperStatus of the destination interface:
dialup-wait:
The route matches, when the ifOperStatus of the
destination interface is either up or dormant.
If the status is dormant, the ifAdminStatus is
set to dialup to bring the interface to the up
state. The datagram will wait until the ifOperStatus
reaches the up state.
For all other states, the routing tables will be
searched for a different matching entry.
dialup-continue:
The route matches, if the ifOperStatus of the
destination interface is up. For all other states,
the routing tables are searched for different matching
entry. However, if the ifOperStatus was dormant and
no other extendend route (with different DstIfMode or
established link) is matching, the ifAdminStatus will
be set to dialup to bring the interface to the up state.
This setting can be used to establish a better
path for a specific service and to use an existing
path for that service as long as the better path
could not be established.
up-only:
The route matches, if the ifOperStatus of the
destination interface is up. For all other states,
the routing tables are searched for different matching
entry.
always:
The route matches independantly of the ifOperStatus
of the destination interface. If it is up, the
interface is used. If the state is dormant,
ifAdminStatus is set to dialup to bring the interface
in the up state. For all other states, the destination
is considered unreachable.
dialup-always:
Same as dialup-wait(1), however, if the ifOperStatus
was dormant, the ifAdminStatus will be set to dialup
to bring the interface to the up state if the value
of ipExtRtMetric1 is the lowest of all matching routes
in this table.
Enumerations:
  • dialup-wait (1)
  • dialup-continue (2)
  • up-only (3)
  • always (4)
  • dialup-always (5)
DstIfIndex
This object specifies the destination interface for the
IP-datagrams belonging to the set. If the value of this
object is set to 0, the datagrams of the set are discarded
and an ICMP destination unreachable datagram is sent
back to the originator.
NextHop
This object is used on point-to-multipoint interfaces
with indirect routes (see ipExrRtType) to specify
the IP-address of the gateway on the network, where
the datagram should be routed to.
Type
This object specifies, on point-to-multipoint interface
whether the datagram shall be sent to the destination
IP address in the IP datagram header (direct) or
to a gateway (indirect). In the later case, the IP-addres
of the gateway is specified by ipExtRtNextHop.
If this object is set to other, the entry is not
used for routing.
The complete entry can also be deleted, by setting this
object to invalid. 
Enumerations:
  • other (1)
  • invalid (2)
  • direct (3)
  • indirect (4)
Metric1
This object is used to specify an order on the entries
in the ipExtRtTable. If a datagram is matching multiple
entries, the entry with the lowest value of ipExtRtMetric1
is choosen. The decision is undefined, when even after
interpreting the metric, there are still multiple entries
matching the IP-datagram.
Metric2
Undefined yet; for further extension
Metric3
Undefined yet; for further extension
Metric4
Undefined yet; for further extension
Metric5
Undefined yet; for further extension
Proto
This object describes, how the route has been gained.
This will normaly be netmgmt, because there is currently
no routing protocol, that is able to handle extended routes.
Enumerations:
  • other (1)
  • local (2)
  • netmgmt (3)
  • icmp (4)
  • egp (5)
  • ggp (6)
  • hello (7)
  • rip (8)
  • is-is (9)
  • es-is (10)
  • ciscoIgrp (11)
  • bbnSpfIgp (12)
  • ospf (13)
  • bgp (14)
Age
This object specifies the age of the route.
