Christian,
The SUP2T-XL and Sup720BXL have the same FIB TCAM size. However the
SUP2T-XL has one shared pool of TCAM for IPv4/IPv6.
The Sup720BXL has a fixed pool TCAM for Ipv4 and one fixed pool for
IPv6. If you want to change this allocation, you have to do a config
change and a reload afterwards.
regards,
Rinse Kloek

Today I tested a Sup2T-XL and a Sup720BXL in the lab with full bgp feeds for
ipv4 and ipv6.
To my understanding the hardware capacity for the FIB TCAM is the same for
Sup720-BXL and Sup2T-XL.

The release notes say:
-XL mode:
· IPv4 and MPLS: Up to 1,007,000 routes
· IPv4 multicast and IPv6 unicast and multicast: Up to 503,000 routes
"These are the theoretical maximum numbers of routes for the supported protocols
(the maximums are not supported simultaneously):"
The above output of the Sup2T-XL seems to say that the Sup2T-XL has a larger
FIB TCAM (2M) than the Sup720-BXL.
