Assuming that no sessions are being terminated at this time, the first 450 callswill be sent to Serial1, and subsequent calls will alternate between Serial0 and Serial1 until the interfacesare full.!interface serial0description 56k link supporting 50 virtual circuitsx25 htc 50!interface serial1description T1 line supporting 500 virtual circuitsx25 htc 500!x25 hunt-group hg-vc vc-countinterface serial0interface serial1!X.25 Load Balancing with Multiple Hunt Groups ExampleThe following example enables X.25 encapsulation on relevant serial interfaces and configures serialinterfaces 1 and 2 to participate in X.25 hunt group “HG1,” and serial interfaces 0 and 3 to participatein X.25 hunt group “HG2.” Serial interfaces 1 and 2 and XOT IP addresses 172.17.125.54 and172.17.125.34 are then associated with hunt group “HG1” (with rotary distribution assigned); and serialinterfaces 0 and 3 are associated with hunt group “HG2” (with vc-count distribution assigned). Thesehunt groups are then added to the routing table, where X.25 route 1111 will use “HG1” and X.25 route1112 will use “HG2”.x25 routing69
