Zero Touch Deployment
A Real World Problem
NetOps:
Config,
monitoring
• Hvert steg i prosessen koster
penger
• Skal du sende kvalifisert
mannskap til hver plass blir det
dyrt og kapasiteten mindre.
• Jo mer kompleks løsning,
desto mer menneskelig factor –
desto større risiko for feil
• ZTD kan bootstrappe via USB,
TFTP eller SMS
Hardware:
Auditing,
shipment
(Wo)Man in a
van: Need
minimal install
process
No console
cable.
A Real World Problem
NetOps:
Config,
monitoring
• Zero touch hjelper i alle deler
av prosessen.
• NetOps – minimer manuell
cut’n’paste – minimer
tidsforbruk og risiko ved
manuell fjernkonfigurasjon
• Onsite personell – Trenger ikke
konsollkabel. Fokus på
installasjon av maskivare –
ikke konfigursjon
• Hardware – Ikke lenger behov
for staging – shipper rett fra
distribusjon. Senker kost.

Hvordan det virker med DHCP
• Prosess
1. Svitsjen booter og mottar DHCP info: defaultgw, tftpd server og boot file name
2. Ved oppstart – svitsj laster ned boot strap
config med TR-069 – CWMP kommandoer +
kommandoer for sikkerhet og andre
nødvendige tjenester (autodeploy.cfg)
TFTPd
BIMS
NOC
DHCP
d
Customer or transit
network
3. Svitsjen kobler til og melder seg som
kandidat til BIMS
4. Config template på BIMs med variabler–
deployes og parametrene fylles ut – fra .CSV
eller interaktivt
5. Svitsjen (som periodisk) kontakter IMC BIMS
server, gjennomfører CWMP samtale,
konfigurasjon lasts ned til enhet.
6. Svitsjen er ferdig konfigurert

Så med ruter
IMC BIMS
Slik virker• det
TR-069 aka CPE WAN
•
Customer DC / NoC
Mgmt Protocol (CWMP)
• Bi-Dir HTTP for
Ingredienser:kommunikasjon mellom
CPE & config server
• IMC Branch Intelligent Management
Software (BIMS) avdelingskontor
enhetskonfig & mgmt.
• En ut-av-boksen TR-069 protokoll
kapabel enhet, MSR ruter eller en
supporter svitsj
Carrier Network
• USB stick med basic config eller tftpserver og DHCP med basic config
(option 150, option 67)
• Onsite “tekniker” for fysisk installasjon
(og potensiell isetting av USB
minnepinne).

• Prosess
1. BIMS satt opp med enhetsid – device
ID (serienummer & OUI) &
konfigurasjonsmal - config template.
Carrier Network
2. USB config peker på IMC server.
3. Oppstart - ruter laster config fra USB.
4. Ruter kontakter IMC server, CWMP
samtale, endelig ruterkonfigurasjon
lastes ned til enhet.
5. Ruter online.

The End?
• Auto-deploy kan fungere alene via
tftp – men TR-069 sikrer at ikke alt
som kobles på kommer på nett.
• Men dette kan også brukes til mye
mer – se ekstramateriell for VPN mm
Zero Touch Deployment:
Tid for demo og lab.
Labguide - oppgaver
Lab oppgaver
Lab miljø:
VSR 1000 – virtuell ruter – vår CPE i dag
Windows 10 – virtuell maskin med IMC-BIMS – DHCP server og tftp server
Fysisk PC – med internett-tilgang og tilgang til virtuelt miljø
Adresser – 192.168.225.0 - alle kan bruke det samme siden nettet er internt
for hver PC.
Oppgave: Sette opp med egen adresse og eget hostname + andre atributter
dere ønsker.

statements must be configured for each
neighbour.
• BGP peer statement subnet allows hub to

• Public Key Infrastructure (PKI) = asymmetric
key infrastructure for encryption &
authentication of network users and data.
• Distributes X.509 digital certificates as public
keys, creates chain of trust rooted at
