There is a 1841 router connected through a primary Metro Ethernet Link 4 Mbps to Internet and a backup ISDN Link through a BRI interface. I have configured a default route pointing Fast Ethernet 0/1 (ME Link) which is tracked with an IP SLA (icmp protocol). When the object is down then a second floating static route with AD 254 is entered in routing table and a call is initiated through the BRI interface. When the object comes up the BRI B channels stay active and the call is not terminated. I have configured the idle-timeout to 100 sec.
Can anyone help to investigate the reason for that behavior?
Thanks in advance!
