Can a RSP720-3C-GE be upgraded to handle 1M routes

[2012jakejake]

Hi,

I have a 7606, with redundant RSP (RSP720-3C-GE with sub-modules 7600-PFC3C , 7600-MSFC4) . 3C is currently only able to handle 256K routes. How can i upgrade to handle 1M routes? Plus the router is already having a 7600-ES20-2X10G with DC3 and a SIP-400. Please advice.

You need RSP720-3CXL in order to be able to support 1M routes. Also you need to make sure that any linecards with DFCs also have 3CXL or 3BXL DFCs otherwise the system will fall back to 3B / 3C mode which will limit the FIB TCAM size to 256K.

By the way as far as I know you cannot upgrade your RSP720-3C to 3CXL in the field.

Can we achieve the upgrade to the RSP720-3c-ge with addition of WS-F6700-DFC3CXL module?

No that is not supported.

What are my upgrade options for the line card 7600-ES20-10G3C if I get a new RSP720-3CXL-GE ? Also can we configure dot1q sub-interfaces on 7600-ES20-10G3C  and layer 3 IP/MPLS VPN ? If there any need of additional license for this?

I will advise that you get in touch with your local Cisco Account Team or partner. They should be able to look at your requirements and suggest an upgrade path. For RSP720 you will need to get new RSP720-3CXL modules as field upgrade of 3C to 3CXL is not supported.
