LinkedIn Challenge - VXLAN Alternatives

Now, I would not say these are alternatives to VXLAN in production environments but these are alternative solutions to solving the networking challenge.

Sorry for taking so long to get these out I sat for my CCIE Written this week, that took a higher priority than this. Never the less here we are.

I could not execute the challenge as designed for a few reasons:

1. I don't have the proper images that support VXLAN
2. I have never used VXLAN and am not familiar with the particulars

I proposed two alternative solutions to this challenge, these are solutions I am familiar with. They share a similar config's but achieve the solution differently.

1. AToM - Any Transport over MPLS
2. L2TPv3 - Layer 2 Tunneling Protocol v3

The Challenge:

My Solution:

My Topology:

Solution #1: AToM

R1: int gi0/0  ip add 10.1.14.1 255.255.255.0  no shut exit R4: int gi0/0  ip add 10.1.14.4 255.255.255.0  no shut exit R2: mpls label protocol mpls mpls ldp router-id Gi0/1 force int gi0/1  ip add 10.1.23.2 255.255.255.0  mpls ip no shut pseudowire-class LAB1  encapsulation mpls exit int gi0/0  xconnect 10.1.23.3 1 pw-class LAB1 no shut exit R3: mpls label protocol mpls mpls ldp router-id Gi0/1 force int gi0/1  ip add 10.1.23.3 255.255.255.0  mpls ip no shut pseudowire-class LAB1  encapsulation mpls exit int gi0/0  xconnect 10.1.23.2 1 pw-class LAB1 no shut exit

Solution #2: L2TPv3

R1: int gi0/0  ip add 10.1.14.1 255.255.255.0  no shut exit R4: int gi0/0  ip add 10.1.14.4 255.255.255.0  no shut exit R2: int gi0/1  ip add 10.1.23.2 255.255.255.0 no shut pseudowire-class LAB2  encapsulation l2tpv3  ip local interface GigabitEthernet0/1 exit int gi0/0  xconnect 10.1.23.3 1 pw-class LAB2 no shut exit R3: int gi0/1  ip add 10.1.23.3 255.255.255.0 no shut pseudowire-class LAB2  encapsulation l2tpv3  ip local interface GigabitEthernet0/1 exit int gi0/0  xconnect 10.1.23.2 1 pw-class LAB2 no shut exit
