send-lifetime

To set the time period during which an authentication key on a key chain is valid to be sent, use the send-lifetime command in key chain key configuration mode. To revert to the default value, use the no form of this command.

send-lifetime start-time {infinite | end-time | duration seconds}

no send-lifetime [start-time {infinite | end-time | duration seconds}]

Syntax Description

start-time

Beginning time that the key specified by the key command is valid to be sent. The syntax can be either of the following:

        hh:mm:ss Month date year

        hh:mm:ss date Month year

•hh—hours

•mm—minutes

•ss—seconds

•Month—first three letters of the month

•date—date (1-31)

•year—year (four digits)

The default start time and the earliest acceptable date is January 1, 1993.

infinite

Key is valid to be sent from the start-time value on.

end-time

Key is valid to be sent from the start-time value until the end-time value. The syntax is the same as that for the start-time value. The end-time value must be after the start-time value. The default end time is an infinite time period.

duration seconds

Length of time (in seconds) that the key is valid to be sent.


Command Default

Forever (the starting time is January 1, 1993, and the ending time is infinite)

Command Modes

Key chain key configuration (config-keychain-key)

Usage Guidelines

Specify a start-time value and one of the following values: infinite, end-time, or duration seconds.

We recommend running Network Time Protocol (NTP) or some other time synchronization method if you intend to set lifetimes on keys.

If the last key expires, authentication will continue and an error message will be generated. To disable authentication, you must manually delete the last valid key.

Examples

The following example configures a key chain named chain1. The key named key1 will be accepted from 1:30 p.m. to 3:30 p.m. and be sent from 2:00 p.m. to 3:00 p.m. The key named key2 will be accepted from 2:30 p.m. to 4:30 p.m. and be sent from 3:00 p.m. to 4:00 p.m. The overlap allows for migration of keys or a discrepancy in the set time of the router. There is a 30-minute leeway on each side to handle time differences.

P-Pending: Neighbor adjacency or redistribution in a suspended or penalized state because the maximum prefix limit has been exceeded.

D-Down: Neighbor adjacency or redistribution is suspended permanently until a manual reset is performed with the clear ip route command.

Address/Source

Shows the peer IP address of the redistribution source.

Interface

Specifies the interface type.

Prefix Count

Displays the total number of learned prefixes by source.

Note Routes can be learned for the same prefix from multiple sources, and the sum of all prefix counts in this column may be greater than the figure displayed in the Prefix Count field.

Restart Count

Number of times that a route source has exceeded the maximum-prefix limit.

Restart/Reset(s)

Displays the time, in seconds, that a route source is in a P (pending) state. If the route source is in an A (stable or normal) state, the displayed time, in seconds, is the time period until penalization history is reset.

Usage Guidelines

Use the shutdown command to disable the service-family protocol for a specific routing instance. The service-family protocol continues to run and the current service-family configurations are available; however the service-family protocol will not create any adjacencies on any interface and will clear the service-family topology database.

Examples

The following example shows the placement of the shutdown command for each configuration level: 

Router(config-router)# shutdown

Router(config-router-sf)# shutdown

Router(config-router-sf-interface)# shutdown

12.2(33)SXI4

This command was integrated into Cisco IOS Release 12.2(33)SXI4.


Usage Guidelines

The split-horizon rule prohibits a router from advertising a route through an interface that the router itself uses to reach the destination. The following are general rules for EIGRP split-horizon:

•Split-horizon behavior is turned on by default.

•When you change the EIGRP split-horizon setting on an interface, all adjacencies with EIGRP neighbors reachable over that interface are reset.

•Split-horizon should typically be disabled only on non-broadcast multi-access interfaces.

•The EIGRP split-horizon behavior is not controlled or influenced by the ip split-horizon command.

To configure split-horizon for an EIGRP address family, use the split-horizon command in address-family interface configuration mode.

To configure split-horizon for an EIGRP service family, use the split-horizon command in service-family interface configuration mode.

Examples

The following example disables EIGRP split-horizon for serial interface 3/0 in address-family 5400: 

Router(config)# router eigrp virtual-name

Router(config-router)# address-family ipv4 autonomous-system 5400

Router(config-router-af)# af-interface serial3/0

Router(config-router-af-interface)# no split-horizon

The following example disables EIGRP split-horizon for serial interface 3/0 in service-family 5400: 

Router(config)# router eigrp virtual-name

Router(config-router)# service-family ipv4 autonomous-system 5400

Router(config-router-sf)# sf-interface serial3/0

Router(config-router-sf-interface)# no split-horizon

Cisco IOS XE Release 2.5

This command was integrated into Cisco IOS XE Release 2.5.

12.2(33)SXI4

This command was integrated into Cisco IOS Release 12.2(33)SXI4.


Usage Guidelines

The route-hold timer sets the maximum period of time for which the NSF-aware router will hold known routes for an NSF-capable neighbor during a switchover operation or a well-known failure condition. The route-hold timer is configurable so that you can tune network performance and avoid undesired effects, such as "black holing" routes if the switchover operation takes too much time. When this timer expires, the NSF-aware router scans the topology table and discards any stale routes, allowing EIGRP peers to find alternate routes instead of waiting during a long switchover operation.

Examples

The following configuration example sets the route-hold timer value for an NSF-aware address family. In the example, the route-hold timer is set to 1 minute: 

Router(config)# router eigrp virtual-name

Router(config-router)# address-family ipv4 autonomous-system 1

Router(config-router-af)# timers graceful-restart purge-time 60

The following configuration example sets the route-hold timer value for an NSF-aware service-family. In this example, the route-hold timer is set to 300 seconds: 

Router(config)# router eigrp virtual-name

Router(config-router)# service-family ipv4 autonomous-system 4533

Router(config-router-sf)# timers graceful-restart purge-time 300
