hi, am try to depoly favilover script on my router RB951G-2HnD but an error occur my code as below:
\
Please fill the WAN interface names
:local InterfaceISP1 ether2
:local InterfaceISP2 ether4
Please fill the gateway IPs (or interface names in case of PPP)
:local GatewayISP192.168.2.1;
:local GatewayISP2 2.2.2.2;
Please fill the ping check host - currently: resolver1.opendns.com
:local PingTarget 208.67.222.222;
Please fill how many ping failures are allowed before fail-over happends
:local FailTreshold 1;
Define the distance increase of a route when it fails
:local DistanceIncrease 2;
Editing the script after this point may break it
-------------- stop editing here --------------
\
Declare the global variables
:global PingFailCountISP1;
:global PingFailCountISP2;
This inicializes the PingFailCount variables, in case this is the 1st time the script has ran
:if ([:typeof $PingFailCountISP1] = “nothing”) do={:set PingFailCountISP1 0;}
:if ([:typeof $PingFailCountISP2] = “nothing”) do={:set PingFailCountISP2 0;}
This variable will be used to keep results of individual ping attempts
:local PingResult;
\
Check ISP1
:set PingResult [ping $PingTarget count=1 interface=$InterfaceISP1];
:put $PingResult;
:if ($PingResult = 0) do={
:if ($PingFailCountISP1 < ($FailTreshold+2)) do={
:set PingFailCountISP1 ($PingFailCountISP1 + 1);
:if ($PingFailCountISP1 = $FailTreshold) do={
:log warning “ISP1 has a problem en route to $PingTarget - increasing distance of routes.”;
:foreach i in=[/ip route find gateway=$GatewayISP1 && static] do=
{/ip route set $i distance=([/ip route get $i distance] + $DistanceIncrease);}
:log warning “Route distance increase finished.”;
}
}
}
:if ($PingResult = 1) do={
:if ($PingFailCountISP1 > 0) do={
:set PingFailCountISP1 ($PingFailCountISP1 - 1);
:if ($PingFailCountISP1 = ($FailTreshold -1)) do={
:log warning “ISP1 can reach $PingTarget again - bringing back original distance of routes.”;
:foreach i in=[/ip route find gateway=$GatewayISP1 && static] do=
{/ip route set $i distance=([/ip route get $i distance] - $DistanceIncrease)}
:log warning “Route distance decrease finished.”;
}
}
}
\
Check ISP2
:set PingResult [ping $PingTarget count=1 interface=$InterfaceISP2];
:put $PingResult;
:if ($PingResult = 0) do={
:if ($PingFailCountISP2 < ($FailTreshold+2)) do={
:set PingFailCountISP2 ($PingFailCountISP2 + 1);
:if ($PingFailCountISP2 = $FailTreshold) do={
:log warning “ISP2 has a problem en route to $PingTarget - increasing distance of routes.”;
:foreach i in=[/ip route find gateway=$GatewayISP2 && static] do=
{/ip route set $i distance=([/ip route get $i distance] + $DistanceIncrease);}
:log warning “Route distance increase finished.”;
}
}
}
:if ($PingResult = 1) do={
:if ($PingFailCountISP2 > 0) do={
:set PingFailCountISP2 ($PingFailCountISP2 - 1);
:if ($PingFailCountISP2 = ($FailTreshold -1)) do={
:log warning “ISP2 can reach $PingTarget again - bringing back original distance of routes.”;
:foreach i in=[/ip route find gateway=$GatewayISP2 && static] do=
{/ip route set $i distance=([/ip route get $i distance] - $DistanceIncrease);}
:log warning “Route distance decrease finished.”;
}
}
}
there is no response in log system neither ISP switeching.
