Works nicely, like on the bigger routers (NCS-55A1 / Cisco 8000) as far
as I can tell. We're using a relatively small feature set (IPv4+IPv6
routing, OSPFv2/v3+BGP, limited MPLS for L2 VPNS) and small routing
tables. Our configurations tend to be rather static, and we mostly use
old-style management protocols (SNMP/SSH/CLI).
How do you deal with OS upgrades, especially if you have tons of them
in the field?
Mark.
Using the multi-step upgrade "install package replace" (or "install
prepare" on the older IOS-XR versions), you can relatively painlessly do
the time-consuming steps (copying/importing the ISO/package
installation) before the actual upgrades. Then, when you are ready to do
the upgrades during your maintenance window, you can just "install
apply" and it is rather quick.
Still, I do prefer the replace one file approach in classic IOS.
Other than that, we only upgrade when really necessary (critical
security bug, new feature). Luckily, that happens very rarely.
Chris.
