The SRXs are moving toward dhcp-relay with https://gerrit.wikimedia.org/r/c/operations/homer/public/+/841460 and the QFX switches already use that feature.
bootp is not an option anymore on multiple platforms
To keep the configuration consistent we should migrate the core routers to use dhcp-relay

Agreed we should add it to the CRs, no reason I can think of not to.
Also I'll think about it in terms of the l3_switch template consolidation. They should get the same but have an 'if' around the section to add the option 82 info:
cmooney@asw1-b13-drmrs> show configuration forwarding-options dhcp-relay relay-option-82
circuit-id {
prefix {
host-name;
}
}Marking this task dependent on DHCP option 97 to reduce the risk of DHCP oddities related to Option 82.

[operations/homer/public@master] Add trust-option-82 to dhcp relay conf for core routers

[operations/homer/public@master] Add trust-option-82 to dhcp relay conf for core routers
Ironic I hadn't seen this comment until today for some reason. Then spent the whole morning and afternoon dealing with DHCP oddities related to Option 82 :)
Anyway things are now working good with the 'dhcp relay' config on the core routers in place of the old 'bootp' setup. An additional piece of config is required on the core routers we don't have on the L3 switches - to trust DHCP packets with option 82 already set. That's merged now and reimage is working in tests.
Anyway we seem to be good here as things are, so we can remove the dependency and work on the Option 97 stuff separately.
