Hi guys,
I need to catch changed routes and pass this to the notification script. Now I see 2 ways so far:
- Check immediate-gw. When switching to ISP2 occurs, the /ip route get [find immediate-gw=9.9.9.9%ISP1] command displays "no such item"
- Catch route flags, if possible in ROS 7. In the case when ISP1 is unavailable and the connection goes through ISP2, the following is displayed:
[admin@Test] > /ip/route/print
Flags: D - DYNAMIC; I - INACTIVE, A - ACTIVE; c - CONNECT, s - STATIC; H - HW-OFFLOADED
Columns: DST-ADDRESS, GATEWAY, DISTANCE
DST-ADDRESS GATEWAY DISTANCE
;;; ISP2
0 As 0.0.0.0/0 lte1 5
1 IsH 0.0.0.0/0 9.9.9.9 2
2 As 9.9.9.9/32 ISP1 2
DAc 10.11.11.0/24 bridge1 0
DAc 10.100.100.0/24 lte1 0
DAc 172.16.25.1/32 ISP1 0
After the connection to ISP1 is restored, the route flag IsH changes to As:
[admin@Test] > /ip/route/print
Flags: D - DYNAMIC; A - ACTIVE; c - CONNECT, s - STATIC
Columns: DST-ADDRESS, GATEWAY, DISTANCE
DST-ADDRESS GATEWAY DISTANCE
;;; ISP2
0 s 0.0.0.0/0 lte1 5
1 As 0.0.0.0/0 9.9.9.9 2
2 As 9.9.9.9/32 ISP1 2
DAc 10.11.11.0/24 bridge1 0
DAc 10.100.100.0/24 lte1 0
DAc 172.16.25.1/32 ISP1 0
Scripting for ROS is not my strong point. I tried writing this, but it doesn't work properly 
:if ([/ip route get [find immediate-gw=9.9.9.9%ISP2]]="no such item") do={
:local DeviceName [/system identity get name];
:local ChatID "xxxxxxxxxx";
:local SendText "\E2\9A\A0 <b>Router - $DeviceName:</b>%0AMain ISP on $DeviceName is DOWN!";
#:log info "ISP1 gateway is down";
/tool fetch url="https://api.telegram.org/botxxxxx:xxxxxxxxxxxxxx/sendMessage?chat_id=$ChatID&parse_mode=HTML&text=$SendText" keep-result=no;
}
If someone help me get it to work I'd really appreciate it.
