EIGRP Manual Summarization
Router(config)#interface fastethernet 0/0 |
Enters interface configuration mode. |
Router(config-if)#ip summary-address eigrp 100 10.10.0.0 255.255.0.0 75 |
Enables manual summarization for EIGRP autonomous system 100 on this specific interface for the given address and mask. An administrative distance of 75 is assigned to this summary route. |
|
NOTE The administrative-distance argument is optional in this command. Without it, an administrative distance of 5 is automatically applied to the summary route. |
Passive EIGRP Interfaces
Router(config)#router eigrp 110 |
Starts the EIGRP routing process. |
Router(config-router)#network 10.0.0.0 |
Specifies a network to advertise in the EIGRP routing process. |
Router(config-router)#passive-interface fastethernet 0/0 |
Prevents the sending of hello packets out the Fast Ethernet 0/0 interface. No neighbor adjacency will be formed. |
Router(config-router) |
Prevents the sending of hello packets out all interfaces. |
Router(config)#no passive- |
Enables hello packets to be sent out interface Serial 0/0/1, thereby allowing neighbor adjacencies to form |
Equal-Cost Load Balancing: Maximum Paths
Router(config)#router eigrp 100 |
Creates routing process 100 |
Router(config-router)#network 10.0.0.0 |
Specifies which network to advertise in EIGRP |
Router(config-router)#maximum-paths 6 |
Set the maximum number of parallel routes that EIGRP will support to 6 |
Unequal-Cost Load Balancing: Variance
Router(config)#router eigrp 100 |
Creates routing process 100 |
Router(config-router)#network 10.0.0.0 |
Specifies which network to advertise in EIGRP |
Router(config-router)#variance n |
Instructs the router to include routes with a metric less than or equal to n times the minimum metric route for that destination, where n is the number specified by the variance command |
