AS Number Available only if you selected the EIGRP routing protocol.
The number that will be used to identify the autonomous system
(AS) area to which the EIGRP packet belongs. The range is
1-65535. The default is 110.
An autonomous system (AS) is a collection of networks that share
a common routing strategy.An AS can be divided into a number of
areas, which are groups of contiguous networks and attached hosts.
Routers with multiple interfaces can participate in multiple areas.
An AS ID identifies the area to which the packet belongs. All
EIGRP packetsare associated with a single area, so all devices must
have the same AS number.
Process Number Available only if you selected the OSPF routing protocol.
The routing process ID number that will be used to identify the
secured IGP that Security Manager adds when configuring GRE.
The range is 1-65535. The default is 110.
Security Manager adds an additional Interior Gateway Protocol
(IGP) that is dedicated for IPSec and GRE secured communication.
An IGP refers to a group of devices that receive routing updates
from one another by means of a routing protocol. Each “routing
group” is identified by the process number.
For more information, see How DoesSecurity Manager Implement
GRE?, page 9-87.
Hello Interval Available only if you selected the EIGRP routing protocol.
The interval between hello packets sent on the interface, from 1 to
65535 seconds. The default is 5 seconds.
Hold Time Available only if you selected the EIGRP routing protocol.
The number of seconds the router will wait to receive a hello
message before invalidating the connection. The range is 1-65535.
The default hold time is 15 seconds (three times the hello interval).
