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

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.
