EIGRP uses a metric to compute the costs to a given network.
EIGRP Metric
The EIGRP metric can be based on several criteria, but EIGRP uses only two of these criteria by
default:
?– Bandwidth: The smallest bandwidth between source and destination
?– Delay: The cumulative interface delay in microseconds along the path
IP-EIGRP: Ext 172.69.40.0 255.255.255.0 metric 2272256 - 1657856 614400
IP-EIGRP: 192.135.245.0 255.255.255.0, - do advertise out Ethernet0/1
IP-EIGRP: Ext 192.135.245.0 255.255.255.0 metric 40622080 - 40000000 622080
IP-EIGRP: 192.135.244.0 255.255.255.0, - do advertise out Ethernet0/1
Table 5-6 debug ip eigrp Output
Field Description
IP-EIGRP Indicates that this is an IP EIGRP packet.
Ext Indicates that the following address is an external destination rather than an
internal destination, which would be labeled as Int.
do not advertise out Indicates interfaces out which EIGRP will not advertise the given route. This
con?¬?guration prevents routing loops (split horizon).
M Displays the computed metric, which includes the sent metric (SM) and the cost
between this router and the neighbor. The ?¬?rst number is the composite metric.
