6704 is just said to be 1:1 with dfc. What we experienced, is that if
you need the full 4G use the 6708, regardless if it's oversubscribed
2:1.

1:2 oversubscribed though correct? The 6704 is 1:1 if that's
important to
the application....

And also keep in mind that WS-X6708-10GE is a true line-rate card...

Mark,
I'm not sure if you have other 10g links, but keep in mind that Cisco
has (at least) two 10g optics - Xenpak and X2 - that are not
intercompatible.
I believe that the 6704-10ge uses Xenpak and the 6708-10gE, which is
the "same" card but with 8 ports, uses X2. If everything else you do
is X2, it might make sense to jump up to the 8 port card to prevent
yourself from having to buy/spare two types of optics.

Hi
I have a prospect for a 10G upstream customer and Upstream ISP
connections. I would need to connect these into our 7609s running RSP
720-3CXL's, at the moment I have found that the WS-X6704-10GE card
may be
suitable.
My technical requirements are:
10Gbps line rate
IPv4
Able to handle full Internet routing table Potentially IPv6 and MPLS
in the future
With the WS-X6704-10GE, there seems to be several options that are
available with it i.e.
Memory Option:
MEM-XCEF720-256M
Catalyst 6500 256MB DDR, xCEF720 (67xx interface, DFC3A)
MEM-XCEF720-512M Cat 6500 512MB DDR, xCEF720 (67xx interface,
DFC3A/DFC3B) MEM-XCEF720-1GB Catalyst 6500 1GB DDR, xCEF720 (67xx
interface, DFC3BXL)
====================================================
Distributed Forwarding Card Option
WS-F6700-CFC
Catalyst 6500 Central Fwd Card for WS-X67xx modules WS-F6700-DFC3B
Catalyst 6500 Dist Fwd Card, 256K Routes for WS-X67xx WS-F6700-DFC3A
Catalyst 6500 Dist Fwd Card for WS-X67xx modules WS-F6700-DFC3BXL
Catalyst 6500 Dist Fwd Card- 3BXL, for WS-X67xx WS-F6700-DFC3C
Catalyst 6500 Dist Fwd Card for WS-X67xx modules WS-F6700-DFC3CXL
Catalyst 6500 Dist Fwd Card- 3CXL, for WS-X67xx
I assume that I would need MEM-XCEF720-1GB and WS-F6700-DFC3CXL?

Mark
