Добрый день!
Cisco IOS Software, 1841 Software (C1841-ADVENTERPRISEK9-M), Version 12.4(24)T4, RELEASE SOFTWARE (fc2)Включены два оператора связи ISP и ISP Reserve.
Track срабатывает как часы. При падении ISP циска переключается на ISP Reserve.

Суть проблемы:
Циска пингуется по адресу ISP Reserve (1.1.1.2) только в момент аварии основного ISP. Надо сделать так, чтобы в обычном рабочем режиме она пинговалась по двум адресам: 2.2.2.2 и 1.1.1.2
