I've heart from a SE, that only Engine 5 linecards do IPv6 in hardware.
As we have some GSRs in our network (12410/12416) and linecards from
Engine 0 to Engine 5, does somebody has experiences with GSR & IPv6 and
can say which linecards do IPv6 in hardware?
Newer links are 10Gbps with SIP/SPA cards (Engine 5) and should do the
trick, but older links are 2.5Gbps with SRP/DPT and SDH framing (which
we are forced to use, because of our cable provider).

Example Linecards:
Engine: 1 - Standard OC48 (2.5 Gbps), OC12/SRP-IR-SC-B=
Engine: 2 - Backbone OC48 (2.5 Gbps), 3GE-GBIC-SC=
Engine: 2 - Backbone OC48 (2.5 Gbps), OC48/SRP-SR-SC=
Engine: 3 - ISE OC48 (2.5 Gbps), 4GE-SFP-LC=
