Chapter 9 Configuring IP Routing
Configuring EIGRP
•
To redistribute static routes into the EIGRP routing process, enter the following command:
hostname(config-router): redistribute static [metric bandwidth delay reliability
loading mtu
] [route-map
map_name
]
• To redistribute routes from an OSPF routing process into the EIGRP routing process, enter the
following command:
hostname(config-router): redistribute ospf pid [match {internal | external [1 | 2] |
nssa-external [1 | 2]}] [metric bandwidth delay reliability loading mtu ] [route-map
map_name ]
•
To redistribute routes from a RIP routing process into the EIGRP routing process, enter the followin
gcommand:
hostname(config-router): redistribute rip
[ metric bandwidth delay reliability load mtu ]
[ route-map map_name ]
You must specify the EIGRP metric values in the redistribute command if you do not have a
default-metric command in the EIGRP router configuration.
Configuring the EIGRP Hello Interval and Hold Time
The security appliance periodically sends hello packets to discover neighbors and to learn when
neighbors become unreachable or inoperative. By default, hello packets are sent every 5 seconds.
The hello packet advertises the security appliance hold time. The hold time indicates to EIGRP
neighbors the length of time the neighbor should consider the security appliance reachable. If the
neighbor does not receive a hello packet within the advertised hold time, then the security appliance is
considered unreachable. By default, the advertised hold time is 15 seconds (three times the hello
interval).
Both the hello interval and the advertised hold time are configured on a per-interface basis. We
recommend setting the hold time to be at minimum three times the hello interval.
To configure the hello interval and advertised hold time, perform the following steps:
Step 1 Enter interface configuration mode for the interface on which you are configuring hello interval or
advertised hold time by entering the following command:
hostname(config)# interface phy_if
Step 2
To change the hello interval, enter the following command:
hostname(config)#
hello-interval eigrp
as-num seconds
Step 3 To change the hold time, enter the following command:
hostname(config)# hold-time eigrp as-num seconds
Disabling Automatic Route Summarization
Automatic route summarization is enabled by default. The EIGRP routing process summarizes on
network number boundaries. This can cause routing problems if you have non-contiguous networks.
