Re: Sigtran Digest, Vol 51, Issue 4

Yes Lukas, but for now we are going to use Single Home, and later maybe the
Multihome setup. So, under the single home scenario if the Gr connection is
lost and the associations get lost, I dont know what happens with the
attached users. I think that they should continue attached but I want to
find out for sure.
Many thanks for your answer,
Guillermo.
