Re: Name two reasons not to use CEF per-packet load balancing.
i want to know if per destination load-balancing all packets of a flow sent out the same interface .why this method be called "load-balancing"?if bwteen a and b lsr has two link ,in cisco ios,default enable per destination load-balancing ,so i must forwarding all packets of a flow e1 of lsr a to lsr b ,another link between a and b is not waste?
I have one doubt pertaining to per-packet load-sharing. In order to connect my two data-centres- A & B, Site A is having two WAN links and Site B is having two WAN links - one from ISP1 (30Mbps link) and the other from ISP2 (50Mbps link). I am doing static route load balancing using same AD values for both the ISPs. I have configured "ip load-sharing per-packet" on both the outgoing interfaces.
The load is getting distributed equally across both the links but total bandwidth utilization across both the links is not going beyond 30Mbps. The combined bandwidth of both links is 80Mbps (50+30). However links are not getting fully utilized even though heavy load is there on the links. Can you please tell me how to make full use of both the wan links at both the ends? OR Can you tell me how I can distribute the traffic across both the links with full utilization. Moreover, my links can be configured statically only at both the ends.
