Ehh sorry it is a lot of writting. Look at LARTC HOWTO 12.4 section. Basicaly if you have ip A.B.C.D then you can base hash source on D for several fixed A.B.C. Then you will end with at most N/256+1 lookups for N ip addresses. devik On Sat, 8 Dec 2001, yangrunhua wrote: > Can you give me an example? > Thanks. > > -----Original Message----- > From: lartc-admin@xxxxxxxxxxxxxxx [mailto:lartc-admin@xxxxxxxxxxxxxxx] > On Behalf Of Martin Devera > Sent: 2001Äę12ÔÂ8ČŐ 15:58 > To: yangrunhua > Cc: lartc@xxxxxxxxxxxxxxx > Subject: Re: [LARTC] How could I do this? > > IMHO u32 with hashes could be used for this.
