Hi everyone, 1. I am setting up a router FEP_DSPU as a DSPU PU 2. Router FEP connects to router FEP_PEER via serial s3 3. FEP_PEER is a DLSW peer router connecting TCP/IP over a serial link to CC_PEER via s2 4. CC_PEER is a DLSW peer and connects to router CC_DSPU via s1. 5. CC_DSPU is configured as a DSPU host. [CC_DSPU]---[CC_PEER]-----------[FEP_PEER]----[FEP_DSPU] s1 s2 s3 a. The DLSW peers are working fine. b. When s1 and s3 links are replaced by Token ring I have end-to-end connectivity. How can I configure s1 and s3 to work as SDLC links instead? Thanks a lot Regards Srikanth Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=4779&t=4779 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
