Consider two routers which have 3 GEs between them (no L2 device between them).
Is it "better" to configure each of these GEs as a standalone L3 connection or to combine them GEs into an etherchannel (802.1ae?) bundle? My $0.02 would be to keep them at L3 and not run another protocol underneath to enable bundling. The question I've heard with this approach is how granular the load splitting works when splitting load across three interfaces. If CEF does per packet load splitting, would the load be (nearly) equal across the three interfaces (eg within 1-2% at all times)? When using per packet CEF, is there an issue with packets being received out of order? (Consider some flow where a large packet is sent over one interface and the following flow packet is small and sent over another interface. The small packet might be received completely before the large packet. Does per packet CEF address this issue?) I had heard that etherchannel (or the IEEE derivative) would support nearly equal load splitting across N interfaces. And it also defines a mechanism so that the receiving router would be able to detect and re-order packets which arrive out of order). Comments? Pointers to relevant docs?
