[c-nsp] Questions about upgrading and image of a Modular IOS

[Ian MacKinnon]

Hi Gert,

We looked into modular some time ago, but I don't imagine much has changed.

Patches were for as you say gaping security holes, not upgrades even of a point release.

How does Cisco currently deal with "modular IOS" upgrades and patches?

Are there patches available at all (and yes, where to find them)?  If yes, can these patches be used to upgrade from, say, SXI1 to SXI2, or will they only fix gaping security holes?  Are the rules for "what will be in a patch and what not" documented somewhere?

We're in the process of upgrading a few boxes from SXI1 to SXI2 due to BGP memory leaks.  Currently, this is "non-modular" code, but I wonder if modular+patches would bring me the fixed BGPD without having to do a full reload...
