packet destination lookup is handled in TCAM on the asr1k. The amount of TCAM is listed on page 11 of: > http://www.cisco.com/en/US/prod/collateral/routers/ps9343/data_sheet_c78-450070.pdf The TCAM size is measured in megs rather than prefixes, as this is a more natural way of handling it. You're right that it's opaque though - the figures for ipv4 are the same as for ipv6 for the ESP40/ESP40/ESP100, and only 2x for the ESP20. It would be very interesting if Cisco could provide some details on how TCAM carving is handled on these boxes.
