hi,
 
i need some help in debugging why my virtual-access3 i/f is flapping. I created a dialer i/f between two ATMs(see below configs) and my BGP doesnt comeup..Can someone help.
 
 
LINEPROTO-5-UPDOWN: Line protocol on Interface Virtual-Access3, changed state to down
2d02h: %LINEPROTO-5-UPDOWN: Line protocol on Interface Virtual-Access3, changed state to up
2d03h: %LINEPROTO-5-UPDOWN: Line protocol on Interface Virtual-Access3, changed state to down
2d03h: %LINEPROTO-5-UPDOWN: Line protocol on Interface Virtual-Access3, changed state to up
