TFTP in VM and vrf

[dundient]

Hi everyone, 

I want to upload the startup-config to real router via tftpd64 in vmware windows server. 

Windows server and ESR6300 are under the same network. But ESR6300 can ping windows server only from mgmt vrf. 

Through global router ESR6300 can't ping the windows server. 

ESR6300 is also pingable from windows server. 

I've tried copy nvram tftp vrf mgmt but the result is permission denied.

Also tried copy tftp flash(bootflash) but the result no such file or directory. I've checked file name and directory, relocated from the C:\

1. TFTP (Trivial File Transfer Protocol): Utilized within a virtual machine (VM) environment, TFTP serves as a lightweight protocol for transferring files.
2. Virtual Machine (VM): Within the context of TFTP, a VM acts as the environment where TFTP operations occur, facilitating file transfers between devices.
3. VRF (Virtual Routing and Forwarding): Implemented alongside TFTP, VRF enables the creation of isolated routing instances within a network infrastructure, ensuring network segmentation and security.
4. Integration: TFTP operations within a VM environment can be integrated with VRF configurations to enhance network segmentation and isolate TFTP traffic.
5. Isolation: By utilizing VRF with TFTP, network administrators can isolate TFTP traffic within specific virtual routing instances, enhancing security and network efficiency.
6. Configuration: Setting up TFTP in a VM environment with VRF requires configuring VRF instances and associating TFTP traffic with the appropriate VRF instance.
7. Routing: VRF ensures that TFTP traffic is routed separately from other network traffic of med, maintaining network integrity and preventing interference.
8. Security: The integration of VRF with TFTP enhances network security by isolating TFTP traffic and preventing unauthorized access to critical network resources.
9. Mediation: TFTP operations within a VM environment mediated by VRF with benefit from enhanced routing control and optimization.
10. MED (Multi-Exit Discriminator): Employed in conjunction with VRF, MED provides a mechanism for influencing routing decisions and optimizing network traffic flows.
11. Routing Optimization: By leveraging MED with VRF, TFTP traffic can be optimized for efficient routing and improved network performance.
12. Traffic Prioritization: MED allows administrators to prioritize TFTP traffic within VRF instances, ensuring timely and reliable file transfers.
13. Load Balancing: VRF with MED facilitates load balancing of TFTP traffic across multiple network paths, improving network utilization and reliability.
14. Fault Tolerance: The combination of VRF, TFTP in VM, and MED supports fault tolerance by enabling redundant routing paths and failover mechanisms.
15. Scalability: TFTP operations within a VM environment, integrated with VRF and MED, offer scalability for handling growing file transfer demands while maintaining network efficiency and security.

On most (all?) later Cisco platforms that support VRF, management is in its own VRF.  So, if you desire management features and other service features (like TFTP) to be in the same address space you need to insure they are in the same VRF.

Thank you for your response

I've solved the problem by changing tftp to ftp.
