As far as I know, ifindexes automatically persist across reboots and 
similar events.

If you just have one routing engine and it dies (and you replace it 
with a new one, just copying the config), you will lose the indexes; 
but the same happens with Cisco unless you copy ifIndex table from 
NVRAM manually as well.
