Connectivity Guide

• Underlay reachability to VTEP peers is provisioned or learned using existing routing protocols.
• The OS10 VTEP sends MAC addresses addition or deletion events at the VXLAN access port to the NSX controller through OVSDB
protocol. The controller then propagates the information to the other VTEPs so that the VTEPs program their forwarding tables
accordingly.
Steps to congure controller-provisioned VXLAN
To congure the NSX controller, follow these steps on each OS10 VTEP:
1 Assign an IPv4 address to a Loopback interface.
2 Create an NVE instance and congure the Loopback interface as NVE source interface.
3 Specify the NSX controller reachability information
4 Assign interfaces to be managed by the controller.
5 (Optional) Enable BFD in the NSX and the VTEP.
For more information about assigning an IPv4 address to a Loopback interface and conguring the Loopback interface as NVE source
interface, see the Congure source IP address on VTEP section in the OS10 Enterprise Edition User Guide. The rest of the congurations
are explained below.
Specify the controller reachability information
In OS10 VTEP, the controller conguration command initializes a connection to an OVSDB-based controller.
OS10 supports only one controller connection at a time.
NOTE
: Currently, the only supported OVSDB-based controller is NSX.
To congure an OVSDB controller on the OS10 VTEP:
1 Enable VXLAN in CONFIGURATION mode.
OS10(config)# nve
2 Changes the mode to CONFIGURATION-NVE-OVSDB from where you can congure the controller parameters.
OS10(config-nve)# controller ovsdb
3 Specify the IP address, OVSDB controller port, and SSL as a secure connection protocol between the OS10 VTEP and the controller in
CONFIGURATION-NVE-OVSDB mode.
OS10(config-nve-ovsdb)# ip ip-address port port-number ssl
The range of port-numberis from 0 to 65535. Congure the port-number as 6640 and the connection type as SSL.
4 (Optional) Specify a time interval, in milliseconds (ms). This is the duration the switch waits between the connection attempts to the
controller.
OS10(config-nve-ovsdb)# max-backoff interval
The range is from 1000 to 180,000 ms. The default is 8000 ms.
OS10# configure terminal
OS10(config)# nve
OS10(config-nve)# controller ovsdb
OS10(config-nve-ovsdb)# ip 10.11.66.110 port 6640 ssl
