Hi Jerry
I had this idea,since in ADSL the IPs are not fixed the only option is per
packet load balancing.but this is the ethernet handoff from ADSL modem u
talking about? in that scenario i may have to do per vlan rate-limiting on
the L3 switch itself right? and on the router i may have to do
router-on-stick with sub-intf,right?
