Description

Ip_forwarding flag for IPv6 is not applied to all the namespaces even if it is set for default in /proc. Although it works fine for IPv4.
Because of this the IPV6 traffic in network namespace is not getting forwarded.
Attached is the log with the issue we are facing in our environment.
