The option to change the VRF context setting is available on the NSX Advanced Load Balancer UI.
The VRF setting can be changed by navigating to and clicking the edit option.
Configuring static routes available under the Management Network does not affect the SE. As part of SE boot-up process, the NSX Advanced Load Balancer Controller only picks the default gateway that is applicable to the specific SE based on the SE management network.
The VRF edit option on the NSX Advanced Load Balancer UI is only applicable to data NICs. The VRF context setting for the management network can be changed using CLI.
This section also explains how to configure NSX Advanced Load Balancer when there are multiple management networks used across SE Groups.
Instructions
Login to the NSX Advanced Load Balancer CLI, and run the following commands:
configure vrfcontext management
static_routes route_id <ID> prefix 0/0 next_hop <IP address of the next hop>
For more information on CLI configuration, see the following snippets.
