Hi all. Im studying for the CCNP-Switching exam. I have a question about MLS's Flow Masks. In my CiscoPress book, the author says:
"The MLS-SE uses flow masks modes to determine how packets are compared to MLE entries in the MLS cache.The flow mask mode is based on the access list configured on the MLS router interfaces. The MLS-SE learns of the flow mask trough MLSP messages from each MLS-RP for wich the MLS-SE is performing Layer 3 switching. " I dont understand why the flow mask mode is based on the access list configured, since all the 3 flow mask modes just look at the DESTINATION IP address. So, if the MLS-RP has an access list that deny some traffic, that traffic just will be forwarded and never will arrive at the switch's backpanel. If the MLS-RP has an access list that permit the traffic, the MLS-SE will cache it and it will only chek the Destination address for Layer 3 switching. So, why are flow mask modes based on the configured access list? Thanks for your help.
