Dialer works then stops


I am running multicast and RIP over a dial on demand PPP multilink ISDN backup circuit. I am using dialer maps and static routes. Some routers dial, connect, learn rip routes and forward traffic with no problems. Others don't work so well with the same config (different IP's/hostnames etc) and IOS. They dial, connect, learn rip routes, forward multicast then just stop after about 15 seconds. The rip routes time out and you can't even ping the other end of the dialer. The idle timer also starts to increase. "Sh ip ro" shows the far end as a directly connected as expected. Before failing the x21 for the real live backup tests i pinged the dialer from one end to the other so as too trigger the connection and prove IP's and CHAP etc. These ping tests worked without fault time after time. It seems once the live traffic passed something went wrong. OSPF is run on the routers but the dialer network is not listed. Any suggestions very welcome. Regards,


Re: Dialer works then stops

Are the failing dialer interfaces configured the same way with regards to interesting traffic (dialer-group) and timeout values (dialer timeout)?
