plus:

- fully automate ingress prefix management
- use maxprefixes with manual reenable on all ebgp sessions

I've been caught with fully automated IRR based per-session prefix
filtering where the customer put the IXP AS macro into their AS macro.

When the customer did a 7007 on this, we accepted everything that they
announced back to us, oy vey.

So you need both.
