Because a limited number of IPv4 addresses still available and the reluctancy of upstream ISPs handing out hundreds op public IPv4 adresses, we would like to set up a central IP pool for our whole network or segments op our network to be used on PPPoE.
This means we do not have to guess the number of IPs we need to add to the PPPoE IP pool of each router with multiple sectors. IPs can then be issued from a central shared pool an available on any sector and router as needed.
I know the routing tables would be quite large as routing tables will include lots of rules for pools devided up into smaller blocks. We're using BGP and need to cater for about 750 users at the moment.
Any suggestions?
