The issue is my tunnel traffic is destined to a single core router on the far end of the links consuming the majority of the BW for any single link. Hence I'm looking at using per-packet method. I don't have any latency sensitive application that I need to worry in this case. Not sure if I need to enable "ip load-sharing per-packet" on L2 port / serial links off dual routers? regards, /virendra > > also , CEF has a default load-sharing per-destination enabled so make sure > to change it under interfaces to load-sharing per-packet > > > best regards > --Abo Zaid > > > On Dec 10, 2007 1:42 PM, Joe Provo <[EMAIL PROTECTED]> wrote: > >> On Sun, Dec 09, 2007 at 05:39:07PM -0800, virendra rode // wrote: >> [snip] >>> In order to distribute traffic (load-sharing) across two links I'm >>> looking at enabling equal cost traffic (per-packet load sharing) going >>> out both serial links as their data processing is overloading one link. >>> The equal cost routes with CEF default load sharing is not distributing >>> the load over the 2 links as expected.
