Cisco Viptela ZTP (Zero Contact Provisioning)

Viptela supplies the automated provisioning of the vEdge routers by a course of referred to as Zero contact provisioning the place the vEdge router be part of the overlay community with out the handbook intervention. Solely pre-requisite to get the ZTP engaged on vEdge is to have web connectivity in order that we are able to get DHCP deal with from that web circuit and likewise get public DNS reachability.

By default manufacturing facility setting when a vEdge router boots it’ll attempt to contact to a URL ztp.viptela.com which is a service hosted by Cisco on the public cloud/web.

How Zero Contact Provisioning works?

The entire steps for the ZTP course of on {Hardware} vEdge routers are listed as under:

• vEdge router after having web connectivity boots up.
• The router then sends a DHCP uncover message and tries to get an IP from the DHCP server of web service supplier.

1. If the DHCP server is reachable the router will get an IP deal with for its ZTP interface.
2. If no DHCP server is reachable the router will then provoke a course of referred to as automated IP detection to get its ZTP interface deal with.

• As soon as the ZTP interface will get the IP deal with from DHCP or auto IP, router will ship a DNS decision request for ztp.viptela.com to public DNS server.
• The DNS server on receiving this request will confirm the vEdge router and can ship again the IP deal with of the vBond orchestrator of specific group.
• The router then tries to achieve the vBond public IP and authenticates itself with vBond by sharing its chassis quantity and serial quantity. vBond can be authenticated on the vEdge router aspect.
• Submit the profitable authentication and validation, vBond shares the IP deal with of vManage and vSmart with vEdge.
• The vEdge router then proceeds to connect with vManage and mutual authentication & validation takes place. As soon as the authentication and validation is full vManage offers the vEdge its system IP deal with.
• The router re-establishes a connection to the vBond orchestrator utilizing its system IP deal with.
• The router re-establishes a connection to the vManage NMS utilizing its system IP deal with and downloads its full configuration.
• The vEdge router additionally does mutual authentication and validation with vSmart controllers utilizing its system IP.
• As soon as the authentication and validation succeeds the vEdge router efficiently joins the Viptela overlay community.

Word: For the ZTP course of to succeed, the vManage NMS should include a tool configuration template for the vEdge router. If the NMS has no template, the ZTP course of fails.
