All,
Do not get the bit-mask interpretation of the 'dlsw icanreach mac-addre'
mixed up with access-list 7xx bit-masks or access-list 11xx bit-masks.
Access lists = 1 = don't care.
Access lists = 0 = CARE
dlsw icanreach/icannotreach = 1 = CARE
dlsw icanreach/icannotreach = 0 = don't care
Over I don't know how many satisfied TAC customers. ... :^)
Regards
Bernard.
