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:

  • igmp (2)
  • ggp (3)
  • tcp (6)
  • egp (8)
  • pup (12)
  • udp (17)

  • ospf (89)
  • pim (103)
  • 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.

Range: -1 to 65535

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.

Range: -1 to 65535

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.

Range: -1 to 65535

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.

Range: -1 to 65535

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.

Range: 0 to 255

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.

Range: 0 to 255

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)
  • ipsec (15)
Age
This object specifies the age of the route.
Description
A textual string describing this extended route.

Length: 0 to 255
