Just because a router uses IPv6, doesn't necessarily mean the ISP
supports it.

Just to make sure, the interface connected to your router is in fact
eth1, and not eth0, right?

Posting the actual output might help.

Even if your interface isn't able to configure a global IPv6 address,
it should still get a link local address starting with fe80.
Also, before modifying /etc/network/interfaces, I would advise doing
ifdown eth1, modifying the file, and then ifup eth1. Instead of inet6
dhcp, I would suggest:

iface eth1 inet6 auto

My understanding is this should use either dhcp6, or RA/NDP to
configure it.

What does the following output:

cat /proc/sys/net/ipv6/conf/all/disable_ipv6
cat /proc/sys/net/ipv6/conf/default/disable_ipv6
cat /proc/sys/net/ipv6/conf/eth1/disable_ipv6
