Your ULAs are all in your ULA /48 prefix. I'm not clear why the cableco would
be using ULAs, but if they do, those address will be in the cableco's ULA /48.
No confusion is possible, and as a border router, it SHOULD drop outbound
packets with source addresses in your ULA /48.

In the router advertisements, the prefix information option for the ULA prefix
would need its A flag turned off.

This is more for v6ops or even ipv6-ops@xxxxxxxxxxxxxxxx. To be honest I
don't know if any of the IPv6 books covers this stuff in detail.
