Field
Description

Codes

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

 P - Passive

No Enhanced IGRP computations are being performed for this destination.

 A - Active

Enhanced IGRP 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 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 Enhanced IGRP 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 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 Enhanced IGRP metric that represents the cost to the destination. The second number is the Enhanced IGRP metric that this peer advertised.

Ethernet0

Interface from which this information was learned.

Usage Guidelines

When you specify an NLSP tag, the router displays the link-state packet database entries for that NLSP process. An NLSP process is a router's databases working together to manage route information about an area. NLSP version 1.0 routers are always in the same area. Each router has its own adjacencies, link-state, and forwarding databases. These databases operate collectively as a single process to discover, select, and maintain route information about the area. NLSP version 1.1 routers that exist within a single area also use a single process.

NLSP version 1.1 routers that interconnect multiple areas use multiple processes to discover, select, and maintain route information about the areas they interconnect. These routers manage an adjacencies, link-state, and area address database for each area to which they attach. Collectively, these databases are still referred to as a process. The forwarding database is shared among processes within a router. The sharing of entries in the forwarding database is automatic when all processes interconnect NLSP version 1.1 areas.

Configure multiple NLSP processes when a router interconnects multiple NLSP areas.


Note NLSP version 1.1 routers refer to routers that support the route aggregation feature, while NLSP version 1.0 routers refer to routers that do not.


If you omit all options, a summary display is shown.

Usage Guidelines

When you specify an NLSP tag value, the router displays the NLSP neighbors for that NLSP process. An NLSP process is a router's databases working together to manage route information about an area. NLSP version 1.0 routers must be in a single area. Each router has its own adjacencies, link-state, and forwarding databases. These databases operate collectively as a single process to discover, select, and maintain route information about the area. NLSP version 1.1 routers that exist within a single area also use a single process.

NLSP version 1.1 routers that interconnect multiple areas use multiple processes to discover, select, and maintain route information about the areas they interconnect. These routers manage adjacencies, link-state, and area address databases for each area to which they attach. Collectively, these databases are still referred to as a process. The forwarding database is shared among processes within a router. The sharing of entries in the forwarding database is automatic when all processes interconnect NLSP version 1.1 areas.

You must configure multiple NLSP processes when a router interconnects multiple NLSP areas.


Note NLSP version 1.1 routers refer to routers that support the route aggregation feature, while NLSP version 1.0 routers refer to routers that do not.


If you omit the keyword detail, a summary display is shown.

Examples

The following command output from the show ipx nlsp neighbors command shows a summary display of three adjacencies on two circuits:

Router# show ipx nlsp neighbors

System Id  Interface  State  Holdtime  Priority  Cir  Adj  Circuit Id
dtp-37     Et1.2      Up     21        64        mc   mc   dtp-37.03
dtp-37     Et1.1      Up     58        44        bc   mc   dtp-17.02
dtp-17     ET1.1      Up     27        64        bc   bc   dtp-17.02

This display indicates the following information about the first circuit (Circuit Id = dtp-37.03):

Multicast addressing is in use (Cir = mc).

The neighbor supports multicast addressing (Adj = mc).

This display indicates the following information about the second circuit (Circuit Id = dtp-17.02):

The broadcast address is in use (Cir = bc).

The first neighbor (System Id = dtp-37) supports multicast addressing (Adj = mc).

The second neighbor (System Id = dtp-17) does not support multicast addressing (Adj = bc). This adjacency explains why the broadcast address is in use on the second circuit.

The following is sample output from the show ipx nlsp neighbors detail command:

Router# show ipx nlsp neighbors detail

System Id       Interface  State  Holdtime  Priority  Cir  Adj  Circuit Id
0000.0C01.EF90  Ethernet1  Up     25        64        mc   mc   0000.0C01.EF90.0C

8 Total IPX routes

Number of routes in the IPX routing table.

No parallel paths allowed

Maximum number of parallel paths for which the Cisco IOS software has been configured with the ipx maximum-paths command.

Novell routing algorithm variant in use

Indicates whether Cisco IOS software is using the IPX-compliant routing algorithms (default).

Net 1

Network to which the route goes.

[3/2]

Delay/Metric. Delay is the number of IBM clock ticks (each tick is 1/18 seconds) reported to the destination network. Metric is the number of hops reported to the same network. Delay is used as the primary routing metric, and the metric (hop count) is used as a tie breaker.

via network.node

Address of a router that is the next hop to the remote network.

age

Amount of time (in hours, minutes, and seconds) that has elapsed since information about this network was last received.

uses

Number of times this network has been looked up in the route table. This field is incremented when a packet is process-switched, even if the packet is eventually filtered and not sent. As such, this field represents a fair estimate of the number of times a route gets used.

Ethernet0

Interface through which packets to the remote network will be sent.

(NOVELL-ETHER)

Encapsulation (frame) type. This is shown only for directly connected networks.

is directly connected

Indicates that the network is directly connected to the router.


When Cisco IOS software generates an aggregated route, the show ipx route command displays a line item similar to the following:

NA      1000 FFFFF000 [**][**/06] via        0.0000.0000.0000,  163s, Nu0

In the following example, the router that sends the aggregated route also generates the aggregated route line item in its table. But the entry in the table points to the null interface (Nu0), indicating that if this aggregated route is the most-specific route when a packet is being forwarded, the router drops the packet instead.

Usage Guidelines

SPF calculations are performed only when the topology changes. They are not performed when external routes change.

The spf-interval command controls how often Cisco IOS software can perform the SPF calculation. The SPF calculation is processor-intensive. Therefore, it may be useful to limit how often this is done, especially when the area is large and the topology changes often. Increasing the SPF interval reduces the processor load of the router, but potentially slows down the rate of convergence.

Examples

The following example sets the SPF calculation interval to 30 seconds:

spf-interval 30
