All, Please can someone confirm a small point for me.
Process switching Packet comes in from an interface and the interface places this packet in memory (SRAM). Packet then gets placed in DRAM, does a routing table lookup and gets forwarded based on the routing table. Fast Switching Packet comes in from an interface and the interface places this packet in memory (SRAM). The packet still stored in SRAM, consults the fast cache table and if it gets a hit, gets forwarded based on the fast cache table NO ROUTING TABLE LOOKUP. CEF Switching Packet comes in from an interface and the interface places this packet in memory (SRAM). The packet still stored in SRAM, consults the FIB table and if it gets a hit, consults the adjacency table and gets f/wd based on these two tables. NO ROUTING TABLE LOOKUP. Is this correct? So not every packet a router receives, does a routing table lookup? Many thx for ur help. ------------------------------------------------------------------------ For more information about Barclays Capital, please visit our web site at http://www.barcap.com.
