-        When we are extending the Layer 2 networking, that is known as L2 bridging.

-        You can create an L2 bridge between logical switch and VLAN.

-        It helps in migrating virtual workloads to physical devices with no impact on IP addresses.

-        When you are using VXLAN in virtual and VLAN in some other place (like physical), then you must do L2 bridging.

-        This is required for VLAN to VXLAN. This is not for VLAN to VLAN, or VXLAN to VXLAN.

-        It supports networking between NSX and Non NSX network.

-        Real time example – P2V, V2V.

To create L2 bridging –

Go to Network & Security > Edge Services > Bridging > Click on + icon

-        Select Logical Switch (for VXLAN)

-        Select Distributed Switch Port Group (For VLAN)

Edge Services

-        NAT

-        Load Balancing

-        Firewall

-        VPN

-        DHCP

-        DNS-Relay

-        Routing

NAT (Network Address Translation)

Reduce public IP consumption by using binding of public to private IP.

We can configure this in our NSX under Edge service option.

1.    SNAT (Source NAT)
2.    DNAT (Destination NAT)

Load Balancer

1. One Arm
2. In Line

Load balancing method supported by NSX:

-        Round Robin

-        Based on least connection

-        Based on URL header

Health Monitoring for Load Balancing method:
