Re: how to reduce routing table entries...

Hello,

there are various ways to achieve that: either you could configure aggregate addresses on your end, or you could filter what is goinf out at your end, or what is coming in at the customer PE end, suing distribute and prefix lists. Check these links for configuration examples:
