Node modify algorithm

---

Node type rules

• Advanced node may have more then one name and interface address may have name
• Router does not imply any extra restrictions or functionality.
• IPC provider can have ipc ip addresses
• Template may not have interfaces at all and must have instead 'template ip address space', also its name may not have aliases or mxs.
• Node with MX must have at least one ip address.

Note

• Interface must have either hw address or/and at least on ip address.
