I want some help regarding connecting cisco routers across a frame relay based TDMA ( Time Division Multiple Access ) Network. In TDMA network, main site (hub) is connected to different remote site having remote unit (each site has differet DLCI). At main site there are two different path, one for transmission (Tx) and other for Receive (Rx). So at main site a Frame Relay switch is used to switch data from TX and RX path to DTE device ( e.g Cisco router). Currently a main cisco router is connected to switch port and differnt remote router connected to remote terminal (star topology). The configuration used is at main site subinterfaces are reated for each remote site and set specific interface dlci for each subinterface). Configuration at main router interface s0 encapsulation frame-relay no keep-alive ( as TDMA has lmi disabled) no ip address interface s 0.1 ip addr 192.168.21.1 255.255.255.0 frame-relay interface-dlci 17 interface s 0.2 ip addr 192.168.22.1 255.255.255.0 frame-relay interface-dlci 18 and so on as depend on number of remote sites. Cofiguration at remote sites interface s 0 encapsulation frame-relay no keep-alive no ip address interface s0.1 ip addr 192.168.21.2 255.255.255.0 frame-relay interface-dlci 17 and same at all remote site routers. How can I replace frame relay switch by using two serial port of Cisco router and route data from both TX and Rx path to LAN ethernet port? I want to eliminate switch and want to take same work with cisco router. My understanding is that cisco router works as frame relay switch by receiving data of a specific dlci from a serial port and swich to different serial port with a differnt or same dlci. Can Cisco router transmit and receive data of same dlci at different serial ports and route these data to LAN ethernet interface? -- _______________________________________________ Get your free email from http://mymail.iname.com Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=8381&t=8381 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
