If using loopbacks on the router you have to have a firewall filter on it to permit traffic to the device even if you have a firewall filter on individual interfaces that would allow/deny traffic

Subject: [EXTERNAL] Juniper configuration recommendations/BCP

After nearly 30 years of being a cisco shop, I'm working on configuring our first pair of Juniper MX204's to replace our current provider-edge cisco.

I've worked through enough of the Juniper documentation/books to have a fairly good handle on how to configure these, but I wanted to check with the list to see if there are any Juniper-Specific gotchas I might run into that isn't documented well.

I've done a bit of googling and am either finding stuff that is largely Cisco-specific or which is generic - all of which I'm rather familiar with based on my past history. Is there anything I should worry about which is Juniper-specific?
