Headquarter and several branch office, Cisco3725 (HQ) anche Cisco-2811 (BO).
WAN connections on Ethernet (transparent bridging over WireLess).
BackUp connection are ISDN-Dialer (DDR Routing).
Dynamic Routing via EIGRP.
No problem in case of TOTAL failure of the "main connection": the EIGRP works very well and the Dial-on-Demand-Routing bring Up the dialer in few seconds.
But in case of poor performances of the "main connection", my EIGRP is not able to follow the degrading and recalculate a new metric, so to switch to the Dialer.
What to do?
Better tuning the EIGRP?
Go to OSPF?
