Hello,

why not use an IP SLA ? In the script below, the router would generate an ICMP ping every three seconds, with the source interface being whatever interface is ISP facing:

R1(config)# ip sla 1
R1(config-ip-sla)# icmp-echo 8.8.8.8 source-interface x
R1(config-ip-sla-echo)# threshold 1000
R1(config-ip-sla-echo)# timeout 1000
R1(config-ip-sla-echo)# frequency 3
R1(config)# ip sla schedule 1 start-time now life forever
