I don't really recall. Hopefully someone more familiar with GFS2 can chime in.

I am running with default TOTEM settings with token time out as 10 secs. Even after I increase the token, consensus values to be higher. It goes on flooding the same message after newer consensus defined time (eg: if I increase it to be 10secs, then I see new membership formed messages for every 10secs)

It does not sound like your network is particularly healthy.
Are you using multicast or udpu? If multicast, it might be worth trying udpu
