Show IP Route: traffic share count?

[davidhuynh5]

When you do a show ip route, what does the "traffice share count 1" mean?

sa26#sh ip route 174.0.0.1
Routing entry for 174.0.0.1/32
  Known via "ospf 2020", distance 110, metric 12, type intra area
  Last update from 10.0.3.250 on FastEthernet0/0, 00:38:02 ago
  Routing Descriptor Blocks:
  * 10.0.3.250, from 174.0.0.1, 00:38:02 ago, via FastEthernet0/0
      Route metric is 12, traffic share count is 1

Hi David,

Traffic share count is used to identify the outgoing packets in various links.OSPF doesn't allow you to do a unequal cost load balancing .With EIGRP , this can be achieved by using the "variance" command (under "router eigrp" ).The " traffic share count " value is an indicaion of how many packets

would be transmitted over the various paths ( equal cost ( in which case it is 1:1 ) / unequal cost ).

With the use of the " variance " command in EIGRP , the router can bemade to transmit traffic in ratio proportion to the metric of the
unequal cost routes.

Hope that clears out your query!!

Hi Ganesh,

But isn't CEF responsible for load-balancing packets over multiple links?

Thanks,
