Total noob, but learning.
I bought a second hand 2851 router (CISCO2851-HSEC/K9-REF)
ROM: System Bootstrap, Version 12.4(13r)T, RELEASE SOFTWARE (fc1)
I'm getting a boatload of memory fragmentation errors, then it failed to ROM image on 'unknown error'.
From what I have read from searches, all point to upgrading software.
How do I get this? How much does it cost to get to the unified version(s)?
Does the upgrade see what licenses/features I have installed and automatically enable them?
Am I allowed to use the software on the Catalyst 2960 and 3750 I have too?
And is 512MB of DRAM the max this router will take? At 256MB now.
Cruising the website is cumbersome and left me more confused then before I searched.
