Dynamic routing with IP/RIPWhat information is propagated by IP/RIP? IP address IP netmask Time Distance Router Local routing Interaction of static and dynamic tables IP masquerading NAT, PAT Two addresses for the router Cable TV net How does IP masquerading work?Simple and inverse masquerading Work DNS forwarding Which protocols can be transmitted using IP masquerading?Only small difference is that Bridging Rator Automatic address administration with Dhcp What are the filter options? Cable modem really belongs to two LANs Dhcp clientDhcp server IP address Network mask Broadcast address How are the addresses assigned? Default state is autoDhcp on, off or auto?
