Greetings, What version(s) of IOS will support IPv6 on a 2511? Thanks. -jav
Cisc's Feature Navigator says 12.2(4)T (and up in the 12.2T) or 12.3(1) with the IP+ feature set. You'll need to up RAM and Flash at 16M/16M each if you haven't yet.
I would say IP plus version 12.3 limited deployment or 12.2T early deployment You'll nead at least 16 MB of DRAM and 16 MB of Flash 12.3(6) c2500-is-l.12.3-6 12.2(15)T11 c2500-is-l.12.2-15.T11 seems to be the lastest revisions available
