Cisco Cisco IOS Software Release 12.4(2)XB6

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

You may have to dampen the amount of changes in order to reduce network-wide churn because cost 
components may change rapidly. 

The following recommended values are intended as a starting point for optimizing a OSPFv3 
network and are based on network simulations that may reduce the rate of network changes. Each 
network may have unique characteristics that require different settings to optimize actual network 
performance. 

You must configure these values for both OSPFv3 IPv4 and IPv6

S1 = ipv6 ospf dynamic weight throughout

Recommended value = 0
Default=100

S2 = ipv6 ospf dynamic weight resources

Recommended value = 29
Default = 100

S3 = ipv6 ospf dynamic weight latency

Recommended value = 29
Default = 100

S4 = ipv6 ospf dynamic weight L2 factor

Recommended value = 29
Default = 100

The following is an example configuration for a VMI interface or on the virtual template when 
running bypass mode:

interface vmi1

…

ipv6 ospf cost dynamic weight throughput 0

ipv6 ospf cost dynamic weight resources 29

ipv6 ospf cost dynamic weight latency 29

ipv6 ospf cost dynamic weight L2-factor 29

…

ospfv3 instance 64 cost dynamic weight throughput 0

ospfv3 instance 64 cost dynamic weight resources 29

ospfv3 instance 64 cost dynamic weight latency 29

ospfv3 instance 64 cost dynamic weight L2-factor 29

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
