The "B" version has 256K entries in the TCAM, and some
is reserved for IPv6, Multicast, etc.  The "BXL" version
has a million entries.  Note that IPv6 takes two entries.
If you are doing a full table, the "B" version might 
survive for a short period, but you need to be planning
on an upgrade to the "BXL" (or reducing the table sizes).
And if you are using DFCs, they too need to be upgraded
at the same time.
