Okay, that gets me a step closer, thanks. I can actually bring up the
connection now.

It seems I don't need to specify explicit addresses for the link. Passing
"ipv6 ," to pppd works sufficiently well from ifcfg-ppp0.
Looking at src/ppp/nm-ppp-manager.c in NetworkManager, I can see that NM can
pass this to pppd:
if (ip6_enabled) {
/* Allow IPv6 to be configured by IPV6CP */
nm_strv_ptrarray_add_string_dup (cmd, "ipv6");
nm_strv_ptrarray_add_string_dup (cmd, ",");
} else
nm_strv_ptrarray_add_string_dup (cmd, "noipv6");
if ip6_enabled is true, which is a condition checked by the caller:
ip6_method = nm_utils_get_ip_config_method (connection, AF_INET6);
ip6_enabled = nm_streq (ip6_method, NM_SETTING_IP6_CONFIG_METHOD_AUTO);
and setting ipv6.method to "auto" does indeed do this, but no routing is set
when the route comes up. Doing "ifup ppp0" has pppd set the route, but this
is disabled by nm-ppp-manager, so I'm not sure how to configure an outside
route.
I've tried setting a route of "::/0" for the ppp connection, but that doesn't
seem to work and I suspect I'm not doing it right. For that matter, if I
disable ipv6 over ppp and just bring up the connection with ipv4, I'm not sure
how/why a global route is set.

I definitely need it to come up automatically.
