IR1101 WAN Monitoring

The IR1101, and possible other routers, has a WAN monitoring capability that uses a Cisco-provided EEM script to respond to a WAN outage by bouncing the WAN interface / power-cycling the cell modem / rebooting the router. The script uses an IP SLA to track an IP address to tell if the WAN is functioning properly.

ip sla 1
 icmp-echo 172.27.166.250
 timeout 6000
 frequency 300
ip sla schedule 1 life forever start-time now
event manager environment wanmon_if_list {cellular0/1/0 {ipsla 1}}
event manager policy tm_wanmon.tcl authorization bypass

None of the configuration examples address using multiple IP addresses as verification that the WAN is functioning. We have a redundant WAN infrastructure where we can patch any hub router without loss of connectivity. 

Can this WAN monitoring script monitor multiple IP SLAs? 

Or is there a way to combine two or more ICMP targets into a single IP SLA?

Thanks!

@Stephen Craven Here is the config for monitoring multiple WAN links with built in WANMon EEM Script:

 

Multiple WAN Link Monitoring Example

 

track 1 ip sla 1

track 21 stub-object

ip sla 1

icmp-echo 172.27.166.250

timeout 6000

frequency 300

ip sla schedule 1 life forever start-time now

track 2 ip sla 2

track 22 stub-object

ip sla 2

icmp-echo 10.27.16.25

timeout 6000

frequency 300

ip sla schedule 2 life forever start-time now

event manager environment wanmon_if_list1 {cellular0/1/0 {ipsla 1} {stub 21}}

event manager environment wanmon_if_list2 {GigabitEthernet0/0/0 {ipsla 2} {stub 22}}

event manager policy tm_wanmon.tcl authorization bypass
