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 I=
Pv6-only networks have been addressed.=20
Your comment mentions LDP IPv6 support. Do you now handle all the major ga=
ps 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.=20
