Having run out of steam on the 7206xr + NPE-G1/G2 platform and an increasing
requirement for Gig ports we are looking at upgrading to 7600'/RSP720-3CXL or
SUP720-3BXL. We don't have any immediate requirements for MPLS so I would like
to avoid upgrading to a MPLS core (and additional license $$) if possible in
the short term.
I have searched both list archives and the various Cisco data sheets but am
unclear on the following:
- Do the 67xx line cards support QinQ or do we have to use the vastlymore
expensive SPA / ES20's? If the 67xx cards do support QinQ are weable to rate
limit on each sub interface?
- Beyond GRE are any other tunneling features supported such as L2PT without
deploying MPLS? We currently use L2TPv3 which is sadly lacking from the
6500/7600.
Thanks,
Dave
