[c-nsp] SXJ - The good, the bad, the ugly?

[Mack McBride]

IOS XE isn't great for modularity but it definitely improves on monolithic IOS.
The division into 8 'chunks' on the ASR 1000 is fairly usable.
Minor version upgrades of the individual packages have gone smoothly.
I don't know how they would do IOS XE for the 6500/7600.

The ASR 9K runs XR and is the logical successor to the 7600.
XR has real modularity and the 9K is fairly mature for the age of the platform.

The 6500 platform really doesn't have a logical successor :(
At some point I am guessing the Nexus 7K is supposed to be it but the maturity is still lacking.

Seems like it.  But given how pathetic that effort was - no buy-in from any other BUs, thus quite limited resources for development, and thus no effective modularity at all, except for fully-modular CDP (yay!) - this was a logical step to expect.

It's frustrating me quite some, especially since we bought 6500/Sup720 instead of 7600/RSP720 specifically because we wanted modularity - but yeah, Cisco politics.

Let's see whether IOS XE will ever mature out of "oh, yes, we have a fully modular operating system and then there's the IOS process running as a single big blob on top of it!"...
