Table: show ipx eigrp topology Field Descriptions

Field Description

Codes

State of this topology table entry. Passive and Active refer to the EIGRP state with respect to this destination; Update, Query, and Reply refer to the type of packet that is being sent.

P - Passive

No EIGRP computations are being performed for this destination

A - Active

EIGRP computations are being performed for this destination

U - Update

Indicates that an update packet was sent to this destination

Q - Query

Indicates that a query packet was sent to this destination

R - Reply

Indicates that a reply packet was sent to this destination

r - Reply status

Flag that is set after the Cisco IOS software has sent a query and is waiting for a reply

42, 160, and so on

Destination IPX network number

successors

Number of successors. This number corresponds to the number of next hops in the IPX routing table.

FD

Feasible distance. This value is used in the feasibility condition check. If the neighbor's reported distance (the metric after the slash) is less than the feasible distance, the feasibility condition is met and that path is a feasible successor. Once the router determines it has a feasible successor, it does not have to send a query for that destination.

replies

Number of replies that are still outstanding (have not been received) with respect to this destination. This information appears only when the destination is in Active state.

state

Exact EIGRP state that this destination is in. It can be the number 0, 1, 2, or 3. This information appears only when the destination is Active.

via

IPX address of the peer who told the Cisco IOS software about this destination. The first n of these entries, where n is the number of successors, are the current successors. The remaining entries on the list are feasible successors.

(345088/319488)

The first number is the EIGRP metric that represents the cost to the destination. The second number is the EIGRP metric that this peer advertised.

The table below describes the fields shown in the display.

Table: show ipx eigrp topology Field Descriptions�Specific Network

Field Description

160

IPX network number of the destination

State is ...

State of this entry. It can be either Passive or Active. Passive means that no EIGRP computations are being performed for this destination, and Active means that they are being performed.

Query origin flag

Exact EIGRP state that this destination is in. It can be the number 0, 1, 2, or 3. This information appears only when the destination is Active.

Successor(s)

Number of successors. This number corresponds to the number of next hops in the IPX routing table.

Next hop is ...

Indicates how this destination was learned. It can be one of the following:

  •  

  • Connected�The destination is on a network directly connected to this router.
  • Redistributed�The destination was learned via RIP or another EIGRP process.
  • IPX host address�The destination was learned from that peer via this EIGRP process.

     

FastEthernet0/0

Interface from which this information was learned

from

Peer from whom the information was learned. For connected and redistributed routers, this is 0.0000.0000.0000. For information learned via EIGRP, this is the peer's address. Currently, for information learned via EIGRP, the peer's IPX address always matches the address in the "Next hop is" field.

Composite metric is

EIGRP composite metric. The first number is this device's metric to the destination, and the second is the peer's metric to the destination.

Send flag

Numeric representation of the "flags" field described in Table. It is 0 when nothing is being sent, 1 when an Update is being sent, 3 when a Query is being sent, and 4 when a Reply is being sent. Currently, 2 is not used.

Route is ...

Type of router. It can be either internal or external. Internal routes are those that originated in an EIGRP autonomous system, and external are routes that did not. Routes learned via RIP are always external.

This is an ignored route

Indicates that this path is being ignored because of filtering

Vector metric:

This section describes the components of the EIGRP metric

Minimum bandwidth

Minimum bandwidth of the network used to reach the next hop

Total delay

Delay time to reach the next hop

Reliability

Reliability value used to reach the next hop

Load

Load value used to reach the next hop

Minimum MTU

Minimum MTU size of the network used to reach the next hop

Hop count

Number of hops to the next hop

External data:

This section describes the original protocol from which this route was redistributed. It appears only for external routes.

Originating router

Network address of the router that first distributed this route into EIGRP

External protocol..metric..delay

External protocol from which this route was learned. The metric will match the external hop count displayed by the show ipx route command for this destination. The delay is the external delay.

Administrator tag

Not currently used

Flag
