Questions for 3 host + jumphost install (baremetal/not vm)

Hi,

I am getting ready to install ICNR2 using 4 Dell 740xds.    I have a few questions:

Can we use different vlan numbers, or must the vlans be labeled as listed in your documentation: 110,111,112, etc.?
Is network bonding supported.?  We usually bond two nics.
What does the IPMI Interface refer to? Is that IPMI interface on the jumphost ?  In our lab, the IPMI network is not segregated.   A specific IPMI interface is not needed; it is handled by routing.  Will not having a specific IPMI interface work with this install?
To clarify, DHCP is NET B interface?
What is the purpose of DMZ, vlan 111?  Our routing will let the public network (Net A) download packages from the internet. Is that enough?

High-level recap of what I understand the steps to be:
1. create bionic jumphost.
2. configure all network vlans, etc.
3. update user_config.sh with correct interfaces and networks
4. create node.json file
5. git clone "https://gerrit.akraino.org/r/icn"
6.  cd icn/
7.  Makefile
8. make install
9.  wait..
