Chapter 38 Configuring IP Unicast Routing
Configuring Protocol-Independent Features
You can configure multiple keys with life times. Only one authentication packet is sent, regardless of
how many valid keys exist. The software examines the key numbers in order from lowest to highest and
uses the first valid key it encounters. The lifetimes allow for overlap during key changes. Note that the
router must know these lifetimes.
Beginning in privileged EXEC mode, follow these steps to manage authentication keys:
To remove the key chain, use the
no key chain
name-of-chain
global configuration command.
Command
Purpose
Step 1
configure terminal
Enter global configuration mode.
Step 2
key chain
name-of-chain
Identify a key chain, and enter key chain configuration
mode.
Step 3
key
number
Identify the key number. The range is 0 to 2147483647.
Step 4
key-string
text
Identify the key string. The string can contain from 1 to
80 uppercase and lowercase alphanumeric characters,
but the first character cannot be a number.
Step 5
accept-lifetime
start-time
{
infinite
|
end-time
|
duration
seconds
}
(Optional) Specify the time period during which the key
can be received.
The
start-time
and
end-time
syntax can be either
hh
:
mm
:
ss Month date year
or
hh

mm
:
ss
date Month
year
. The default is forever with the default
start-time
and the earliest acceptable date as January 1, 1993. The
default
end-time
and
duration
is
infinite
.
Step 6

}
(Optional) Specify the time period during which the key

default
end-time
and
duration
is infinite.
Step 7
end
Return to privileged EXEC mode.
Step 8
