Category:  IPv6

One of my readers successfully deployed LDPv6 in their production network:

We are using LDPv6 since we started using MPLS with IPv6 because I was used to OSPF/OSPFv3 in dual-stack deployments, and it simply worked.

Not everyone seems to be sharing his enthusiasm:

Now some consultants tell me that they know no-one else that is using LDPv6. According to them “everyone” is using 6PE and the future of LDPv6 is not certain.

In a recent blog post, Donal O Duibhir claims IPv6 is faster than IPv4… 39% of the time, which at a quick glance makes as much sense as “60% of the time it works every time”. The real reason for his claim is that there was no difference between IPv4 and IPv6 in ~30% of the measurements.

Unfortunately he measured only the Wi-Fi part of the connection (until the first-hop gateway); I hope he’ll keep going and measure response times from well-connected dual-stack sites like Google’s public DNS servers.
