[j-nsp] EX9200 DHCP Relay

[chris at sdnessentials.com]

Okay, so the syntax is what I'm seeing on that doc for the most part (plus your recommended overrides).
 
Thank you!

Basically everything is moving to jdhcpd.. It's only really licensed
 on MX iirc (shouldn't be on 9200?)
 
 set forwarding-options dhcp-relay overrides allow-snooped-clients
 set forwarding-options dhcp-relay overrides always-write-giaddr
 set forwarding-options dhcp-relay overrides trust-option-82
 set forwarding-options dhcp-relay overrides send-release-on-delete
 set forwarding-options dhcp-relay server-group DHCP-1 1.2.3.4
 set forwarding-options dhcp-relay group DYNAMIC active-server-group DHCP-1
 set forwarding-options dhcp-relay group DYNAMIC interface ae1.101
 
 For most networks, you probably don't need those overrides, but if you
 have something else downstream doing DHCP snooping and option 82
 insertion, you have to tell it to trust it..

I've also read that it's kind of buggy (or was in 2012...). I also tried labbing this using some Fireflies and a VMX in Junosphere but couldn't get it working.
