We have a PFC3B and all the linecards have DFC3Bs and we cannot hold the full internet routing table
So I'm going to suggest we need to get the PFC3BXL upgrade. My question is with regards to the DFCs, are we going to have to upgrade them to DFC3BXL or can we upgrade the memory using MEM-XCEF720-1GB.
Many Thanks in advance
And can you also confirm that just fitting the extra memory to a module with a DFC3B installed won't do anything?
Yes, I have confirmation that this will not work at all. The reason is because the TCAM size on the DFC3BXL is different from the DFC3B.
For your other question about the part number, I think the best thing for you to do is contact your Cisco system engineer and account manager. I don't want to give you wrong information since I don't deal with part number daily.
