Configuring IP Unicast Routing
Verifying Configuration
EXAMPLE
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.
