Cisco Cisco IOS Software Release 12.4(22)YD

Use the following configuration guidelines for disabling split horizon in EIGRP:

By default split horizon is enabled in EIGRP.  You can disable split horizon by entering the no ip 
split-horizon eigrp command for the respective autonomous system number.

interface vmi number

no ip split-horizon eigrp as-number

Enter the following command to disable the ip redirects on the vmi interface when you are 
configuring the vmi interface for EIGRP.

interface vmi number

no ip redirects

Use the following configuration guidelines for setting EIGRP values of radio link metrics: 

EIGRP monitors the following metrics on an interface allowing the tuning of the EIGRP metric 
calculations; use the metric weights router configuration command:

metric weights tos k1 k2 k3 k4 k5

where 

tos denotes type of service (currently, it must always be zero) and use the following default 

values for weights:

    k1 - 1

    k2 - 0

    k3 - 1

    k4 - 0

    k5 - 0

The no metric weights command restores the K-values to the above listed defaults:

Most configurations use the Delay and Bandwidth metrics with Bandwidth taking precedence. 

You must set the weights identically on all routers in an autonomous system. 

If you wish to use the default k-values you do not need to enter the metric weights 
command.

 Change Based Dampening:

ip50-1(config)#int vmi 4

  ip50-1(config-if)#eigrp 100 interface dampening-change 40

Default Value for Change Based Dampening: 50%

To enable change-based dampening using the default Value, enter the following command: 

eigrp 100 interface dampening-change

To disable change-based dampening, enter the following command: 

no eigrp 100 interface dampening-change
