Title:
  cloud-init crashes with IPv6 routes

Status in cloud-init:
  Expired

Bug description:
  
  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
          via: 2001:db8:abcd:bbcf:fe::2

  KeyError: 'NETMASK1'

  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.
