Configuring The Switch Sdm Template; Default Sdm Template - Cisco ME 3400 Software Configuration Manual

Chapter 6 Configuring SDM Templates
An IPv4 route requires only one TCAM entry. Because of the hardware compression scheme used for
Note
IPv6, an IPv6 route can take more than one TCAM entry, reducing the number of entries forwarded in
hardware.
