MPLS gives lots of interesting features
- helps to build new customer services (VPN)
- and to save money (Traffic Engineering)
MPLS makes our life much more difficult
- much more difficult for operation people to understand what they do
- much more difficult for engineers to troubleshoot
You often have to wait for new features you would like to use
You loose other features because they are not “vpn-aware” (i.e. NAT, FW)
If you are one of the first customer using new features like MPLS/VPN in a live-network, the vendors support is greeeeeaaaaaaaaaat!
The real problems are not technology related...
And after all, it is great fun…
