Public bug reported:
I have static routes specified for two networks, and during cloud-init an error
occurs as it tries to make use of NETMASK1.
# Network 2
eth1:
addresses: # List of IP[v4,v6] addresses to assign to this interface
- 2001:db8:abcd:abce:fe::1000/96
routes: # List of static routes for this interface
- to: 2001:db8:abcd:abce:fe::0/96
via: 2001:db8:abcd:bbce:fe::2
# Network 3
eth2:
addresses: # List of IP[v4,v6] addresses to assign to this interface
- 2001:db8:abcd:abcf:fe::1000/96
routes: # List of static routes for this interface
- to: 2001:db8:abcd:abcf:fe::0/96

Additional Info:
1. Using KVM on a private server
2. See above configuration details that cause an issue. Note in the
documentation I could only find an example of an ipv4 route, so maybe you could
enhance the documentation with an example for ipv6 if possible.
