I'm a bit confused about the load sharing modes and switching modes interaction.
My understanding is the following, please correct me if I'm wrong:
1) load sharing can be done in 3 different modes:
1.1 per source-destination IP@ pair
In this case all packets corresponding to a given source-destination pair will be forwarded to the same link, so will not be shared between the outgoing links
1.2 per destination IP@
In this case all packets that are to be sent to a given destination (no matter from what source are coming) will be forwarded to the same link, so will not be shared between the outgoing links
1.3 per packet
In this case all packets corresponding to a given destination will be distributed on all the outgoing links, first packet on the first link, second packet on the second link etc, so the packets for the same destination are shared between all the outgoing links.
2) there are 3 different switching modes:
2.1 Fast switching
2.2 Process switching
2.3 CEF switching
3) the above mentioned load-sharing modes and switching modes are interdependent as follows:
1.1 can be used only with CEF
1.2 can be used only with Fast switching
1.3 can be used with either CEF or Process switching
4) How can these 4 configuration (1.1, 1.2, 1.3 with CEF, 1.3 with Process switching) be set in the router?
