Public bug reported:
In template/openswan/ipsec.conf.template, both leftnexthop and rightnexthop
connection parameters are assigned like below,
leftnexthop=%defaultroute
rightnexthop=%defaultroute
With this settings, ipsec addconn command is failing for ipv6 addresses
like below

Looks like with IKEv1, parsing defaultroute for ipv6 addresses has
problems.
When addresses are given for leftnexthop, instead of %defaultroute, ipsec
addconn is working for ipv6.
i.e modified the template like below
leftnexthop={{vpnservice.external_ip}}
#rightnexthop (i.e not using rightnexthop)
So, neutron shouldn't use %defaultroute for leftnexthop and
rightnexthop and instead assign ip6 addresses from vpnservice object.
