Hi,

 

According to document http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/isg/configuration/xe-3s/asr1000/isg-xe-3s-asr1000-book/isg-ipv6.html, it is possible:

Restrictions for ISG IPv6 Support

  • Layer 2 connected interfaces are not supported. Only Layer 3 routed in-band IPv6 sessions are supported.

 

Session Coexistence on ISG Interfaces

The following session combinations can exist on the same ISG interface in Cisco IOS XE Release 3.5S and later releases:

  • Native IPv6 and native IPv4 sessions

 

Regards

I did not find any information about l3-connected dual stack configuration..

 

There may be two distinct sessions for one client - ipv4 and ipv6..  but this is not what I need

 

Hi,

 

If you want a single session for IPv4 and IPv6, l2-connected is prerequisite. Please see:
