Hi Mark,

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.
We've re-used WS-X6704-10GE (from our 6500 without DFC3CXL daughter card)
My technical requirements are:
10Gbps line rate
10G => yes
IPv4
Able to handle full Internet routing table
Potentially IPv6 and MPLS in the future
We're implementing all of these features without (as from now) any issue
except VPLS which needs ES20/ES40 or ES(combo)
We're also using IPv4 (sparse mode with anycast RP ) /IPv6 multicast
with embedded RP, pseudowire, L3VPN with MPLS.
As far as it goes 6VPE is also supported... (We also tested in lab,
traffic-engineering with CRS1 in the tunnel path and it has worked at
10Gb rate)
For whatever reason CISCO recommended a 4gb RAM RSP memory upgrade if
the 7600 need but I'm not convinced about this recommendation.
(Note that if you need to upgrade you need to purchase 2x4Gb in case of
redundant RSP)
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?
Yes. WS-F6700-DFC3CXL becomes handy if you're planning to use netflow as
the NDE(we extensively use it at full flow) is handle by the Forwarding
card.
(So the RSP7203CXL won't handle NDE burden) Again, more RAM would help
to have more room for NETFLOW cache. But maybe this RAM is useful for
another feature that I'm not awre of.
Netflow is useful and the only way (we found) to monitor IPv6 traffic on
this platform as IPv6 MIBs are not available on this architecture.
Regards
Mark
