Re: Dual stack IPv6 for IPv4 depletion

Greg,

After investigating what a previous poster said about Cisco and Juniper, I'm getting the feeling that not all major 
impediments to running MPLS over IPv6-only networks have been addressed. 

Your comment mentions LDP IPv6 support.  Do you now handle all the major gaps identified the the IETF MPLS IPv6 Gap 
Analysis (RFC7439) from this last January?

https://tools.ietf.org/html/rfc7439#section-3

It seems like their are still gaps in the MPLS spec itself before IPv6 has parity with IPv4 in MPLS.

We added LDP IPv6 support in SR OS 13.0.R1 for Alcatel-Lucent 7x50 platforms
earlier this year.

MPLS requires an IPv4 core. You can't run an IPv6-only infrastructure  because neither CSCO or JNPR have implemented 
LDP to distribute labels for IPV6 prefixes.

Not true - Cisco have it in IOS XR since 5.3.0.

Juniper expect to start shipping it later in 15.

Mark.
