Re: [OSL | CCIE_RS] Frame-Relay P2P

The clocking is always provided by the DCE side therefore it has to be set.   Dan Which plat forms have you found that you don’t have to set the clocking for a DCE interface?   GL   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Daniel Fredrick Sent: Thursday, 22 June 2006 10:32 PM To: [EMAIL PROTECTED] Cc: ccie_rs@onlinestudylist.com; Jamie Costabilo Subject: Re: [OSL | CCIE_RS] Frame-Relay P2P   Yeah... I ran into the same issue before. I had to set the clock rate on the DCE side as Scott said. I noticed that it was only with the 2500/2600 series... Why is that?   Thanks, Dan   On 6/21/06, Scott Morris <[EMAIL PROTECTED]> wrote: If you're connecting two 2500 series devices back to back, you'll need a clock rate on the DCE side.  In addition, if you aren't using a frame switch in the middle, you'll want to do "no keepalive" on both serial links.   As a note, in your configs below, those interface types aren't what you'd see on a 2500.  :)     Scott Morris, CCIE4 (R&S/ISP-Dial/Security/Service Provider) #4713, JNCIE #153, CISSP, et al.
