Had a buddy who said he could send us a 8/40. This long term would be
better than our 7200VXR routers. Thinking about a solution without having
to upgrade to ASR for now.
Want some thoughts on the following:
1. Need to be able to handle full 1 Gigabit of transit (and backup link of
200Meg) at some point or at least a 2.5 Gbps connection total at some point
as the highest ever pushed.
On the GSR series, it's all about the linecard(s). You really want the
4-port GE card, as it's built on the Engine 3 architecture and can do
what you want.
The GRP-B only have 512MB of ram so full tables going to be possibly out of
the question. I know we could possibly filter down but really want to run
full table.
The PRP-1 which we could max out at 2GB of ram
The PRP-2 which we could max out at 4GB of ram
GRP-B would be quite tight. A prior employer hasn't called any of my
contacts looking for help with routing table problems yet, so I don't
think it's hit the limit, but soon...
Would we need to install 5 SFCs?
The 008 uses 3xSFC and 1-2xCSC. You need at least 4 ..C for normal
operation of Engine 1/2/3 cards. You need at least one CSC for normal
operation of Engine 0 cards, but you don't want Engine 0 cards anyway.
Do you think long term this router could work as we believe max capacity we
would need is around 2.5Gbps period for this router?
Could we start out with GRP-B and run full tables for IPv4 and IPv6 with
possibly 200Megs being pushed over transit?
If your cards are Engine 3, they'll serve you well up to the
2.5Gbps/slot limits. If your xRP has enough RAM for all of its tables
and your linecards have enough RAM for the FIB copy, you'll be fine. I
miss these boxes, but they do have a steep learning curve.
