listen address bug

Hi, I've been debugging a bird6.conf (doing two ASN's) for almost two days, finding each time only one half working, and so being convinced it should work. So finaly I could made a clear conclusion: table as5; table as6; # router id 1.2.3.68; # # mysterious failure: #listen bgp address 2001::1a port 179; #listen bgp address 2001::2a port 179; # this works fine: listen bgp address 2001::2a port 179; listen bgp address 2001::1a port 179; # 8< ----- So by these I'd like to report. -- Leo
