Overview of VMware Edge Services Gateway (ESG) and Distributed Logical Router (DLR)

-
                          VMware ESG vs DLR




ESG
DLR
-        It’s always a VM.
-        We use ESG for North-South. It means, going outside from datacenter towards the external network or internet.
-        If you have logical switches in different transport zone, then you can use ESG.
-        ESG is for different transport zone, but DLR is for same transport zone.
-        It supports dynamic routing as well as static routing.
-        It supports OSPF and BGP.
-        It supports both the routing protocol at the same time.
-        It is for centralized routing.
-        Since it is a VM, so it can have maximum of 10 interfaces.
-        On one interface, we can have maximum 200 sub-interfaces which will be connected as trunk interface.
-        ESG has internal interface which connects with South. Means, it connects to DLR. (Transit Network).
-        Physical router will be Uplink interface.


-        It’s a kernel module.
-        It splits in to two components.
  1. DLR
  2. DLR Control VM
-        Name of DLR kernel module is nsx-vdrb. It exists on each ESXi hosts.
-        We use DLR for East-West routing. Means, routing within your datacenter.
-        Benefits of using DLR: -
-        If we remove DLR, so where we have router? We have router on each ESXi host.
-        DLR only do routing if logical switches are in same transport zone.
-        When we deploy DLR, it activates on those ESXi host which participate in that transport zone.
-        It supports dynamic routing as well as static routing.
-        It supports OSPF or BGP.
-        It doesn’t support both routing protocol at the same time.
-        It is distributed routing.
-        It has two interfaces as Internal and Uplink. And third uplink is related to management. Total 1000 interfaces.
-        Internal Interface
-        It connects towards the south. With Logical switches.
-        Maximum it can have 991 interfaces.
-        Uplink Interface
-        It connects with either physical router or ESG.
-        Maximum it can have 8 uplinks
-        Management Interface
-        Number of interfaces is 1
-        Total 10000 interface can be on single host.
-        When we talk about cloud then we give one DLR to each tenant. Where they can create logical switches and connect to DLR.
-        Maximum 250 DLR can be on single ESXi host.

How to migrate the N-VDS as the host switch to VDS 7.0 in NSX-T 3.x

-

  Hello There, In this article, i am covering how to migrate the ESXi host switch from N-VDS to VDS 7.0 switch in NSX-T 3.2.x version. When using N-VDS as the host switch,  NSX-T  is represented as an opaque network in  vCenter Server . N-VDS owns one or more of the physical interfaces (pNICs) on the transport node, and port configuration is performed from  NSX-T Data Center . You can migrate your host switch to  vSphere  Distributed Switch (VDS) 7.0 for optimal pNIC usage and manage the networking for  NSX-T  hosts from  vCenter Server . When running  NSX-T  on a VDS switch, a segment is represented as an  NSX-T  Distributed Virtual Port Groups. Any changes to the segments on the  NSX-T  network are synchronized in  vCenter Server. We have an NSX-T environment running with NSX-T 3.2.2.1 version. this environment was designed and implemented with NSX-T 2.x version and that time we used the N-VDS as host switch configuration on the transport nodes bcuz VDS was not supported that time.

Issue details:-   Password remediation tasks on SDDC manager getting failed with below error. However, we are able to connect SSH with root password on the vROPS appliances, no issues with credentials. I checked Operations logs on SDDC manager and found below logs, indicating the SSH connectivity issues from SDDC to vROPS appliances. Tried to do SSH vROPS appliance from SDDC manager, getting below error... Seems some issue with ECDSA key.. Resolution:- SSH to vROPS appliance and retrieve the ECDSA ssh keys as below. Now, we have 2 options to update the correct SSH keys for vROPS appliance on SDDC manager known_Hosts files located at below location.   /root/.ssh/known_hosts   /etc/vmware/vcf/commonsvcs/known_hosts   /home/vcf/.ssh/known_hosts   /opt/vmware/vcf/commonsvcs/defaults/hosts/known_hosts First option is manually copy and paste the SSH key on all the known_hosts files and restart the SDDC manager services and then try to remediate the password again. it will be successful this

How to Import/Register a VM into vRA portal

-
Image
You can import an unmanaged virtual machine to a vRealize Automation environment. An unmanaged virtual machine exists in a vCenter but is not managed in a vRealize Automation environment and cannot be viewed in the vRA portal . Once you import an unmanaged virtual machine, the virtual machine is managed by using the vRealize Automation management interface. you can see the virtual machine on the Managed Machines tab or the Items tab. Please follow below steps to Import/Register VM into a vRA portal. Log in to vRealize Automation as a fabric administrator and as a business group manager. If you are importing virtual machines that use static IP addresses, prepare a properly configured address pool.  If you use bulk import to import a virtual machine with a static IP address that is allocated to another virtual machine, the import fails. Create a Blueprint and should not have even network attached as well. See below snapin. Create Network profile that shoul
