Release Notes for Cisco IOS Release 12.4(24)GC2
Use the following configuration guidelines when disabling PPP keepalives:
•
You can turn off the PPP keepalive messages to decrease overhead when the radio alerts the router
with a PADT message that the layer-2 RF connection is no longer available. Turning off the PPP
keepalive messages may also avoid the potential for the router to terminate the connection based on
missed PPP keepalives over a poor RF link.

•
To turn off the PPP keepalive messagess, enter the following command for the virtual-template.

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