L2TP Network Server address within VRF - possible?

Dear colleagues.
Could you please tell whether LNS service address can be within a VRF other than default ?
I’m on rolling release 1.4.

Thank you,
Alex

HI all!

May be someone knows - is it possible: would the LNS can work if its ip-address assigned in some vrf?

I did this and got the logs:
{
set interfaces dummy dum0 address ‘10.10.10.1/32’
set interfaces dummy dum0 description ‘LNS loopback to terminate L2TP’
set interfaces dummy dum0 vrf ‘LNS’
}

Seems that LNS do not lesten his port in this case.
Does anybody know - are there some configuration options exist for LNS in vrf?
Or may be such config just shouldn`t work at all?
