We are currently a mix of Juniper and Cisco.  With the Cisco routers eBGP
peering with providers, exchanges, and customers.

We will be reintroducing Juniper as peering routers.  While I have some old
Juniper BGP peering policies I can build from, I would like know what is
working, or not working, well for others.

For example:
- How many BGP groups do you use?
- How are they organized, and does it simplify or complicate policy design?
- Do you have large import/export policies, or do you chain smaller
policies together?
- What "knobs" do you have in your policies and how do you organize them...
(reject, lower-pref, raise-pref, prepend, etc...)?
- Do you use policies to put prefixes into specific RIB groups?  For what
purpose?
- Is anyone aware of a Best Practices guide for Junos BGP policy design?

Thanks,
Rick
