Configure Load Balancing

[khalid731]

Hello everyone,

I have designed and configured this project, but I faced few problems if you can help me to finalize it. 

1- IP telephony are not working, since I configured the basics.

2- Load balancing need to be configured.

Thanks in advance,

Hello,

I think I remember this project from a while ago. It looks like you have Vlan 75 configured as the voice Vlan, but the ports connected to the IP Phones are not assigned to this Vlan ?

Also, load balancing between which devices should be achieved ?

[Georg Pauwen]

What are the requirements for this network ? First of all, which devices are supposed to be layer 2 and which layer 3 devices ?

I would suggest to start out with configuring all inter-switch links as trunks. Also, you need to get your IP addressing sorted out before configuring anything. Your layer 2 switches have two Vlans with IP addresses, this won't work, and only one Vlan will have connectivity.

The requirements are to have Voice and Data Vlan, connect all branches, configure HSRP and Load Balancing.
both core and distribution should be layer three and the access switch is layer two.
And yes I am not good in Cisco I think what i configured is not correct, but can you help me do this?

[khalid731]

Yes a while ago I posted a topology buy that was a different one. 

I think this is the correct one, but please correct me if I am wrong. 

and load balancing should be configured in core and distribution layers.

Hello,

I have made some changes to your configurations, the ephones get IP addresses now. It took several hours to remove all the errors, and I have not assigned management IP addresses to anything, since you have overlapping IP addresses with the voice Vlan (Vlan 75). All switches run VTP so the Vlans are propagated. There were so many errors with pretty much everything that I cannot list them all, please revise the configs and try to figure out how it works.

Load balancing between layer 2 devices requires a port channel, you need to decide first which should be the dual links between the devices, and then configure the port channels...

Attached the revised file...

Looks like your basic configuration is incorrect-, You are not extending your  L2 correctly between each site,

For instance, the Khoshhai Khan site has two access switches interconnected between two Khoshhai distribution switches and then between DC distribution switches but those two access switches have different vlans, sw1 (76-77), sw1 (75,77) however on the interconnected links between the distribution are are not trunks and also the edge distribution switches vtp databse are not carrying all the vlans 75-75-77 for those two access switches.

It also seems you are manually pruning throughout the estate but allowing various tagged vlans and negating others going to the same device over different interconnects.
