We switched this over to using ephemeral configs:
https://www.juniper.net/documentation/en_US/junos/topics/concept/ephemeral-configuration-database-overview.html
This seems to have dramatically reduced configuration time (at the
expense of being slightly less clear).
It also has the bonus that our IRR filters no longer show up in the
main configuration, and 'show | compare' is back to being fast again.
The downside seems to be that these can blow up the router somehow...
there's a big warning about it in the py-ez code:
https://github.com/Juniper/py-junos-eznc/blob/master/lib/jnpr/junos/utils/config.py#L750
There are also some warnings about use with GRES and NSR. They explain a
bit about GRES, but they don't say what's wrong with NSR. For IRR, it
seems that if the static database contains an "allow all" and the
ephemeral database contains the IRR filter, you should be good. Did you
get Juniper to confirm your use case is correct?
I asked them in my JTAC case, but so far they responded with "who told
you to ask us"... I'm waiting to see if they get back to me with better
information.
Meanwhile, I deployed this on one of our routers to test, and it seems
to be working fine so far.
