I have an IPv4/MPLS network consists of purely Cisco routers. I'm deploying Cisco 6PE feature to transport IPv6 traffic between PoP sites across the MPLS backbone.
Do other vendor routers support 6PE? There's possibility that other vendor routers will be introduced to the network as PE routers in the future. What type of integration is required in the future if I turn on 6PE on existing Cisco PE routers now?
