DESCRIPTION
"This table allows the user to determine the source of an IP
address or set of IP addresses, and allows other tables to
share the information via pointer rather than by copying.
For example, when the node configures both a unicast and
anycast address for a prefix, the ipAddressPrefix objects
for those addresses will point to a single row in this
table.
This table primarily provides support for IPv6 prefixes, and
several of the objects are less meaningful for IPv4. The
table continues to allow IPv4 addresses to allow future
flexibility. In order to promote a common configuration,
this document includes suggestions for default values for
IPv4 prefixes. Each of these values may be overridden if an
object is meaningful to the node.
All prefixes used by this entity should be included in this
table independent of how the entity learned the prefix.
(This table isn't limited to prefixes learned from router
advertisements.)"

"An advisory lock used to allow cooperating SNMP managers to
coordinate their use of the set operation in creating or

In order to use this lock to coordinate the use of set
operations, managers should first retrieve
ipAddressTableSpinLock. They should then determine the
appropriate row to create or modify. Finally, they should
issue the appropriate set command, including the retrieved
value of ipAddressSpinLock. If another manager has altered
the table in the meantime, then the value of
ipAddressSpinLock will have changed, and the creation will
fail as it will be specifying an incorrect value for
ipAddressSpinLock. It is suggested, but not required, that
the ipAddressSpinLock be the first var bind for each set of
objects representing a 'row' in a PDU."

DESCRIPTION
"This table contains addressing information relevant to the

This table does not contain multicast address information.
Tables for such information should be contained in multicast
specific MIBs, such as RFC 3019.
While this table is writable, the user will note that
several objects, such as ipAddressOrigin, are not. The
intention in allowing a user to write to this table is to
allow them to add or remove any entry that isn't
permanent. The user should be allowed to modify objects
and entries when that would not cause inconsistencies
within the table. Allowing write access to objects, such
as ipAddressOrigin, could allow a user to insert an entry
and then label it incorrectly.
Note well: When including IPv6 link-local addresses in this
table, the entry must use an InetAddressType of 'ipv6z' in
order to differentiate between the possible interfaces."

DESCRIPTION
"The type of mapping.
Setting this object to the value invalid(2) has the effect
of invalidating the corresponding entry in the
ipNetToPhysicalTable. That is, it effectively dis-
associates the interface identified with said entry from the
mapping identified with said entry. It is an
implementation-specific matter as to whether the agent
removes an invalidated entry from the table. Accordingly,
management stations must be prepared to receive tabular
information from agents that corresponds to entries not
currently in use. Proper interpretation of such entries
requires examination of the relevant ipNetToPhysicalType
object.
The 'dynamic(3)' type indicates that the IP address to
physical addresses mapping has been dynamically resolved
using e.g., IPv4 ARP or the IPv6 Neighbor Discovery
protocol.
The 'static(4)' type indicates that the mapping has been
statically configured. Both of these refer to entries that
provide mappings for other entities addresses.
The 'local(5)' type indicates that the mapping is provided
for an entity's own interface address.

ipDefaultRouterTable OBJECT-TYPE
SYNTAX SEQUENCE OF IpDefaultRouterEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"The table used to describe the default routers known to this
entity."
::= { ip 37 }
ipDefaultRouterEntry OBJECT-TYPE
SYNTAX IpDefaultRouterEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"Each entry contains information about a default router known
to this entity."
INDEX {ipDefaultRouterAddressType, ipDefaultRouterAddress,
ipDefaultRouterIfIndex}
::= { ipDefaultRouterTable 1 }
IpDefaultRouterEntry ::= SEQUENCE {

SYNTAX InetAddressType
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"The address type for this row."
::= { ipDefaultRouterEntry 1 }
ipDefaultRouterAddress OBJECT-TYPE
SYNTAX InetAddress
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"The IP address of the default router represented by this
row. The address type of this object is specified in
ipDefaultRouterAddressType.
Implementers need to be aware that if the size of
ipDefaultRouterAddress exceeds 115 octets, then OIDS of
instances of columns in this row will have more than 128
sub-identifiers and cannot be accessed using SNMPv1,
SNMPv2c, or SNMPv3."

ipDefaultRouterIfIndex OBJECT-TYPE
SYNTAX InterfaceIndex
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"The index value that uniquely identifies the interface by
which the router can be reached. The interface identified
by a particular value of this index is the same interface as
identified by the same value of the IF-MIB's ifIndex."
::= { ipDefaultRouterEntry 3 }
ipDefaultRouterLifetime OBJECT-TYPE
SYNTAX Unsigned32 (0..65535)
UNITS "seconds"
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The remaining length of time, in seconds, that this router
will continue to be useful as a default router. A value of
zero indicates that it is no longer useful as a default
router. It is left to the implementer of the MIB as to
whether a router with a lifetime of zero is removed from the
list.
For IPv6, this value should be extracted from the router
advertisement messages."

ipDefaultRouterPreference OBJECT-TYPE
SYNTAX INTEGER {
reserved (-2),
low (-1),
medium (0),
high (1)
}
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"An indication of preference given to this router as a
default router as described in he Default Router
Preferences document. Treating the value as a
2 bit signed integer allows for simple arithmetic
comparisons.
For IPv4 routers or IPv6 routers that are not using the
updated router advertisement format, this object is set to
medium (0)."
