Agreed as well.

We did put some pressure on Cisco and Juniper some 2 years or so ago. We
have LDPv6 support in IOS XR, but support is still immature in IOS and
IOS XE.

We've just rolled out Junos 16.1 on our MX boxes, which is where support
has been introduced. We'll do some lab testing first, but we're unlikely
to enable it across the board because of dodgy support in IOS XE.

At this stage, if we can get basic MPLSv6 forwarding done minus all the
fancy stuff (VPN's, TE, e.t.c.), that'll be a win. However, I don't
forecast that possibility until 2H'19, or even early 2020.

Mark.
