In addition, one side needs to act as the frame relay DCE. Use the 'frame-relay intf-type dce' command to accomplish this.

Well, it's been a while since I worked with FR. But if you think about a "true" FR circuit, DLCIs are locally significant but both the customer prem equipment and the FR switch have to have matching DLCIs. It's essentially a logical circuit ID that needs to be agreed to by both end points in order for communication to take place. If you have three routers, you can configure one to act as a FR switch. Then two spur routers can talk, via the "switch," on different DLCIs. > Unless, they are defined the same on both routers, does it > work!! > Here is my config: > R5#ri s1.1 > Building configuration... > > Current configuration : 147 bytes > ! > interface Serial1.1 point-to-point > ip address 1.1.1.1 255.255.255.0 > ip router isis > frame-relay interface-dlci 102 > clns router isis > end > > R5# > > > R6#ri s0.1 > Building configuration... > > Current configuration : 200 bytes > ! > interface Serial0.1 point-to-point > ip address 1.1.1.2 255.255.255.0 > ip router isis > ip pim sparse-dense-mode > frame-relay interface-dlci 102 > clns router isis > isis circuit-type level-1 > end > > R6#ping 1.1.1.1 > > Type escape sequence to abort. > Sending 5, 100-byte ICMP Echos to 1.1.1.1, timeout is 2 seconds: > !!!!! > Success rate is 100 percent (5/5), round-trip min/avg/max = > 32/32/36 ms > R6# > > > Now change the dlci # on R6: > > R6#ri s0.1 > Building configuration... > > Current configuration : 200 bytes > ! > interface Serial0.1 point-to-point > ip address 1.1.1.2 255.255.255.0 > ip router isis > ip pim sparse-dense-mode > frame-relay interface-dlci 201 > clns router isis > isis circuit-type level-1 > end > > R6#ping 1.1.1.1 > > Type escape sequence to abort. > Sending 5, 100-byte ICMP Echos to 1.1.1.1, timeout is 2 seconds: > ..... > Success rate is 0 percent (0/5) > R6# > > > Can any one explain?? > Thank you. > Sincerely, > CN > > > > > > > _________________________________________________________________ > Help STOP SPAM with the new MSN 8 and get 2 months FREE* > http://join.msn.com/?page=features/junkmail Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=65455&t=65455 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
