load-sharing per-packet with EIGRP

Unanswered Question
Mar 4th, 2009


How can I load balance, per packet, between 2 fast-ethernet interfaces on a 2811 router running EIGRP, from the same IP source to the same IP destination?

Both links have the same metric and shown in the routing table.


I have this problem too.

Hello Danny,

EIGRP provides two equal cost paths to CEF.

To perform per packet load-sharing

int fx/y

ip load-sharing per-packet

int fx/z

ip load-sharing per-packet

do it on both routers

be aware that some types of traffic like VoIP can be severely affected by per packet load balancing

so per-packet can be an improvement or a worse problem

Hope to help
