The bug is not valid.
Ping6 works fine; was missing the security rule for allowing icmp v6.
After adding:
neutron security-group-rule-create --protocol icmp --ethertype IPv6 --direction
egress 4cf607a6-537f-4893-8531-70ba23895b3d
neutron security-group-rule-create --protocol icmp --ethertype IPv6 --direction
ingress 4cf607a6-537f-4893-8531-70ba23895b3d
the scenario works fine with DVR.
@Scollins and folks I regret the inconvenience :(
Looks at the bright side; it works with DVR :)

Title:
routing with dhcpv6-stateful addressing is broken with DVR
Status in neutron:
Invalid
Bug description:
Not able to ping v6 address of vm on a different network. With legacy router.
Setup has one controller/network node and two compute nodes.
Steps:
0. Add security rules to allow ping traffic.
neutron security-group-rule-create --protocol icmp --direction ingress
94d41516-dab5-413c-9349-7c9bc3a09e75
1. create two networks.
2. create ipv4 subnet on each (for accessing vm).
3. create ipv6 subnet on each with dhcpv6-stateful addressing.
neutron subnet-create dnet1 1111:1::1/64 --name d6sub1 --enable-dhcp
--ip-version 6 --ipv6-ra-mode dhcpv6-stateful --ipv6- address-mode
dhcpv6-stateful
4. create a router (not distributed).
5. add interface to router on each of the four subnets.
6. boot a vm on both networks.
7. Log into the guest vm and configure inteface to receive inet6 dhcp
address; use dhclient to get v6 address.
8. Ping v6 address of the other guest vm. Fails!
ubuntu@dvm11:~$ ping6 2222:2::4
PING 2222:2::4(2222:2::4) 56 data bytes
From 1111:1::1 icmp_seq=1 Destination unreachable: Address unreachable
From 1111:1::1 icmp_seq=2 Destination unreachable: Address unreachable
From 1111:1::1 icmp_seq=3 Destination unreachable: Address unreachable
Note: As we need to modify interface settings and use dhclient, ubuntu cloud
image was used. One may need to set MTU to 1400 for communicating with ubuntu
cloud image.
