Chapter 4 - RouteFinder Software An IP address is a combination of a network number and a host number or ID. IP address masks are used to specify the network or subnet portion of the IP address. IP addresses and masks are 32-bit values. These are usually provided in what is known as the dotted decimal notation. The net mask specifies the network or subnet portion of an IP address. The net mask is a 32-bit value presented in a dotted decimal notation.
RouteFinder MTASR1-100 User Guide The Advanced tab controls the timers, Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS) options, the default route, filters, and Static Routes. In most cases, you should not have to change any of the timers (i.e., default TTL, reassembly timeout, RIP response time and RIP route aging time). The DNS Resolver is supplied for remote Telnet clients when the router is configured for remote access and the terminal server application is enabled.
Chapter 4 - RouteFinder Software Open Shortest Path First (OSPF) Open Shortest Path First (OSPF) is a common TCP/IP routing protocol that provides robust and efficient routing support in the most demanding Internet environments. OSPF calculates routes using the number of routers, the transmission speed, expected delays, and the cost of the route. Version 2 of the OSPF protocol is designed to be run internal to a single Autonomous System.
RouteFinder MTASR1-100 User Guide IPX Setup The IPX Virtual Port Setup dialog box controls the four frame types, and the WAN port setup. The Advanced tab enables IPX routing, auto learn of Ethernet network numbers, and the distributed name of the RouteFinder. The RIP and SAP default timers should not have to be changed for most applications. Disabling IPX and SPX Watchdog Spoofing in the Bandwidth Optimization group has proven effective under certain circumstances with Citrix clients.
Chapter 4 - RouteFinder Software The Advanced tab contains options which control the routing of the protocol and auto learn of Ethernet network numbers, defines the broadcast name of the RouteFinder, and IPX filtering. If bridging of IPX packets is desired, IPX routing must be disabled and frame type support for the frame type must be enabled.
