Now i am constructing a FR network ,the network center is a 7507 router with a PA-MC-8E1/120,the branch is a 3640 with a NM-2CE1B.And i want to assign 2 pvcs for each 3640 to FR net.The line between branch and ceenter is 2M ,so i think i need on CE1 port only. This is the first time for me to touch E1 port , Could anyone give me some sample cofigs or the link to the config on web? Any help would be greatly appreciated. frank _________________________________ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
