Filtering is only useful when combined with route summarization
It is best to filter （allow） the default and summary prefixes only in the Enterprise Edge to remotesites or site-to-site IPsec VPN networks
IGPs （for example EIGRP or OSPF） are superior to route filtering in avoiding in inappropriatetransit traffic through remote nodes or inaccurate or inappropriate routing updates
The primary limitation of router filtering is that it can only be applied on outbound updates
第1题：
A. The broadcast address, and AS number

D. EIGRP routing, network number, and AS
第2题：

D.Route summarization is compued automatically by the router
E.Routing traffic load is reduced when used in stub network links
F.An efficient algorithm is used to build routing tables,using automatic updates
G.Routing tables adapt automatically to topology changes.
