when i config " ip helper-address ..." command, the router can take the role of
dhcp relay agent. but if the interface has two ip addresses configued,what i need know is that, when routers forward dhcp discovery packets, which address will be used as the relay agent address (giaddr), primary or secondary address, even randomly
selected ?
my platform are cat6509 and cat2948g, i actually need primary address be
giaddr address. if cisco devices set the giaddr address randomly, is there some commands configued to force routers use primary or seconday address ? or ,is this related to ios version?
i know there is command " cable dhcp-giaddr policy" on CMTS, is there something like this on routers and switch platform?
