Chapter 8 Interface and Subinterface Management

EIGRP

The EIGRP area describes the EIGRP configuration of the interface on each active autonomous system.
This area contains the following information:
•
•
•
•
IS–IS
The IS-IS area contains the following information:
•
•
•
•

Note
•
Note By default, all interfaces are configured as IS-IS Circuit-type Level 1-2.
OL-4930-01
Interface—Lists the active EIGRP routing processes on the router. Each routing process handles
routing updates for a single autonomous system. The routing process only is active if it is deployed
on at least one network.
Bandwidth Utilization (%)—Percentage of bandwidth that may be used by EIGRP on the interface.
Values greater than 100 percent may be configured; this can be useful if the bandwidth is set
artificially low for other reasons
Hold Time (sec)—Hold time during which the device will wait for a hello packet to be received on
the specified interface and EIGRP autonomous system number. The hold time should be at least
three times the hello interval.
Hello Interval (sec)—Frequency at which the device will send hello packets on the specified
interface and EIGRP autonomous system number.
Area Tag—Identifies the IS-IS routing area that the interface participates in. If multiyear IS-IS is
configured on the device, the IS-IS area must be named; otherwise, this value may be an implicit
null tag. This attribute is read-only.
Level 1 Hello Interval—Length of time between hello packets generated on the interface for level 1
routing. With smaller hello intervals, topological changes are detected faster, but there is more
routing traffic.
Level 1 Metric—Cost of the interface for IS-IS level 1 (intra-area) route calculation.
Level 1 Priority—Level 1 priority. The priority is used to determine which router on a LAN will be
the designated router or designated intermediate system (DIS). The router with the highest priority
will become the DIS. In the case of equal priorities, the highest MAC address breaks the tie.
Level 2 Hello Interval—Length of time between hello packets generated on the interface for level 2
routing.
Level 2 Metric—Cost of the interface for IS-IS level 2 (inter–area) route calculation.
Level 2 Priority—Level 2 priority.
Status—Indicates whether or not IS-IS routing is enabled or disabled. This attribute is read-only.
Enable button—Enables IS-IS routing on the interface.
To enable IS-IS on an interface, the user must specify an IS-IS routing process that is already
deployed on the device. If the process does not exist, the action will fail.
Disable button—Disables IS-IS routing on the interface.
