Design VPLS over MPLS Network and more

[Hannibal]

Hi Dear Cisco Community

Let me to create this post to find out what your experience has been on this topic and if it is possible to implement the following design.

Based on our medium level of knowledge VPLS/MPLS, we want to create a VPLS in which Site 1 will have two different paths through two different MPLS routers connected to the Core of our MPLS Network, as shown in the figure.

1. The Vlan running on the VPLS will be the Vlan 100, Subnet 192.168.1.0/24 (This is will not be the real IP)
2. The IP Address on Access Port on SW-1 is 192.168.1.10/24 (This is will not be the real IP)
3. The IP Address on Access Port on SW-2 is 192.168.1.20/24 (This is will not be the real IP)

Also, we would like to test the redundancy at the NIC level offered by the "NIC Teaming" function of the operating system (Microsoft, Linux, etc.) to connect a Server with two network cards, one to each Switch.

For this case, NIC Teaming will be configured for physical redundancy and not for adding bandwidth; that is, one NIC active and the other on standby. This means that only the active NIC will be transmitting on the channel or switch where it is connected. In case of failure, the standby NIC will assume the active role and the communication will continue without being interrupted.

In other words, we want to try having two different paths but only one will be in communication while the other path will remain on standby.

Other Sites could be connected and also be part of the VPLS, Vlan 100 and the same VPLS/Vlan/Subnet but with only a single connection over the only MPLS router available in those Sites.

I would like to know your experiences on this topic and how feasible and reliable you see the design.

With my best regards

Hi Community

Basically what we want is to create a single VPLS and taking advantage of the active/standby configuration that NIC Teaming allows us, we want to connect both NICs in two different interfaces with different paths to the same MPLS Core Router but which belong to the same VPLS.

We know that both NICs cannot be active/active because it could cause a conflict for the router to receive traffic from the same IP address on two different ports.

If this is not possible, we would have the option of creating a second backup VPLS and we would have a NIC in each of them, in the same active/standby state and with the same Virtual IP.

My best regards

I have idea but I need time to more check it 
you can use multi chassis Port-channel

Hi 

Reviewing a bit what is multi chassis Port-channel, I think I cannot apply it in this VPLS design issue that I show in the previous figure.
