Hi, this is with reference to the free BSD networking code for ipv6. Could any body tell why in link local addresses & other link local related things they are storing if_index in the second 16bits of the address. for eg there will be statement like ia->ia_addr.sa_addr.sin_add16[1] = ifp->if_index. Please tell me its significance & how it is useful & why u have chosen to use as such. regards ravi prasad __________________________________________________________________ Get your own FREE, personal Netscape Webmail account today at http://webmail.netscape.com/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
