My 3662 router has 4 WAN interfaces.
3 are configured as frame relay.
4 th one configured as point to point HDLC and connected to 2M radio link to connect with backup site.
Ciscoworks WAN monitor shows lot of internal resets ONLY for the HDLC link.( this link has 425 resets whereas other links shows zero rests)
Any idea on the cause of this problem ?
