I would like to know what the best type of switching mode is for router interfaces. I have site to site VPNs across the WAN. Should I use "no ip route-cache" interface command? What other options are there? Does it matter if you are running VPNs vs Frame relay? Is there an article someone can show me?
This is what I was wanting. I do have two more questions.
I read that fast switching is not desirable on low speed interfaces when data is fed from a higher speed interface.
I have VPNs that have FastEthernet interfaces for LAN input and Ethernet interfaces for output on 1721's. I also have a 2600 that has an Ethernet for LAN input and 128 Kb (ISDN) for output. One other setup is 2600's with Ethernet interfaces for LAN input and T1 interfaces (1.5 Mb) for output.
1. Should I enable CEF for all interfaces except the ISDN interface since it is much slower?
2. I have a hub and spoke topology. Should I use the command "ip route-cache same-interface" on the hub interfaces for maximum performance? Or will this be a performance hit?
