I'm sure someone can shed some light on the this, it's doing my head in! I've been at it for 7 hours and I'm sure there must be some decent explaination. I'm setting up Frame Relay Home Lab as per Chris Bryant, here is the switch config: http://www.thebryantadvantage.com/Frame%20Relay%20Switch.htm All is well apart from R2, where I have configured a multipoint sub-interface 1.123 Sometimes I see (looped) when doing a show int and on the 2610 that I've configured as a Frame Relay switch, I see this, it's continously up and down. FRAME_SWITCH# sh i 08:27:37: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial1/2, changed sta te to down FRAME_SWITCH# sh i 08:27:47: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial1/2, changed sta te to up FRAME_SWITCH# sh i 08:27:56: %FR-5-DLCICHANGE: Interface Serial1/2 - DLCI 221 state changed to ACTI VE FRAME_SWITCH# sh i 08:28:06: %FR-5-DLCICHANGE: Interface Serial1/2 - DLCI 221 state changed to INAC TIVE FRAME_SWITCH# sh i 08:28:07: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial1/2, changed sta te to down FRAME_SWITCH# sh i 08:28:17: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial1/2, changed sta te to up I have switched cables, also gone from S0 to S1 but no joy. Would really appreciate any input to help. Thanks a million.

"notice that even that I'm going to 2 different IP addresses I use the same DLCI, that's because, for data to get to router 3 (3.100) it has to go through router 1 (2.100) in the first place, it's a spoke to spoke communication" The topology is HUB/SPOKE - 1.100 & 2.100/3.100 On 7 Apr 2006 12:41:29 -0700, "ciscodagama@gmail.com" >> Show run: R2

The part you quote probably refers to a different set-up where the FR switch is also configured to allow the spoke to spoke communication. I would suggest that you first get the simple huband spoke configuration working and then work with variations of that config to get the spoke to spoke working.
