bgp4PathAttrTable

The BGP-4 Received Path Attribute Table contains information about paths to destination networks received from all BGP4 peers.

The indexes of the table are bgp4PathAttrIpAddrPrefix, bgp4PathAttrIpAddrPrefixLen, bgp4PathAttrPeer.

Description

Implemented Specifications

1.3.6.1.2.1.15.6.1.1

bgp4PathAttrPeer

IpAddress

read-only

The IP address of the peer where the path

information was learned.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.15.6.1.2

bgp4PathAttrIpAddrPrefixLen

Integer32{(0,32)}

read-only

Length in bits of the IP address prefix

in the Network Layer Reachability

Information field.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.15.6.1.3

bgp4PathAttrIpAddrPrefix

IpAddress

read-only

An IP address prefix in the Network Layer

Reachability Information field. This object

is an IP address containing the prefix with

length specified by

bgp4PathAttrIpAddrPrefixLen.

Any bits beyond the length specified by

bgp4PathAttrIpAddrPrefixLen are zeroed.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.15.6.1.4

bgp4PathAttrOrigin

INTEGER{igp(1),egp(2),incomplete(3)}

read-only

The ultimate origin of the path

information.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.15.6.1.5

bgp4PathAttrASPathSegment

OCTET STRING{(2,255)}

read-only

The sequence of AS path segments. Each AS

path segment is represented by a triple

<type, length, value>.

The type is a 1-octet field which has two

possible values:

1 AS_SET: unordered set of ASs a

route in the UPDATE

message has traversed

2 AS_SEQUENCE: ordered set of ASs

a route in the UPDATE

message has traversed.

The length is a 1-octet field containing the

number of ASs in the value field.

The value field contains one or more AS

numbers, each AS is represented in the octet

string as a pair of octets according to the

following algorithm:

first-byte-of-pair = ASNumber / 256;

second-byte-of-pair = ASNumber & 255;

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.15.6.1.6

bgp4PathAttrNextHop

IpAddress

read-only

The address of the border router that

should be used for the destination

network.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.15.6.1.7

bgp4PathAttrMultiExitDisc

Integer32{(-1,2147483647)}

read-only

This metric is used to discriminate

between multiple exit points to an

adjacent autonomous system. A value of -1

indicates the absence of this attribute.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.15.6.1.8

bgp4PathAttrLocalPref

Integer32{(-1,2147483647)}

read-only

The originating BGP4 speaker's degree of

preference for an advertised route. A

value of -1 indicates the absence of this

attribute.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.15.6.1.9

bgp4PathAttrAtomicAggregate

INTEGER{lessSpecificRrouteNotSelected(1),lessSpecificRouteSelected(2)}

read-only

Whether or not the local system has

selected a less specific route without

selecting a more specific route.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.15.6.1.10

bgp4PathAttrAggregatorAS

Integer32

read-only

The AS number of the last BGP4 speaker that

performed route aggregation. A value of

zero (0) indicates the absence of this

attribute.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.15.6.1.11

bgp4PathAttrAggregatorAddr

IpAddress

read-only

The IP address of the last BGP4 speaker

that performed route aggregation. A value

of 0.0.0.0 indicates the absence of this

attribute.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.15.6.1.12

bgp4PathAttrCalcLocalPref

Integer32{(-1,2147483647)}

read-only

The degree of preference calculated by the

receiving BGP4 speaker for an advertised

route. A value of -1 indicates the

absence of this attribute.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.15.6.1.13

bgp4PathAttrBest

INTEGER{false(1),true(2)}

read-only

An indication of whether or not this route

was chosen as the best BGP4 route.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.15.6.1.14

bgp4PathAttrUnknown

OCTET STRING{(0,255)}

read-only

One or more path attributes not understood

by this BGP4 speaker. Size zero (0)

indicates the absence of such

attribute(s). Octets beyond the maximum

size, if any, are not recorded by this

object.

This object is implemented as defined in the corresponding MIB files.

Creation Restriction

The table cannot be created.

Modification Restriction

Objects in this table cannot be modified.

Deletion Restriction

Objects in this table cannot be deleted.

Access Restriction

The table can be read only if there is a BGP route and the field value of bgpPeerAdminStatu in the bgpPeerTable is start bgp4PathAttrMultiExitDisc and bgp4PathAttrLocalPref, bgp4PathAttrCalcLocalPref: The values of the three objects range from -1 to 2147483647. However, the value scope defined by command lines is from 0 to 4294967295. If the value that the MIB reads through the command lines exceeds the defined maximum value, the MIB can read the value 2147483647.
