Check Route Path

[HeadQuaker]

Hello,

The Company has one main site and plenty of externals sites everywhere in Europe.

What I NEED to check the route path to every externals sites because on each network path, there are 2 lines:
- The main network line
- The backup

We have to know if the main line is up or down.

I have already something that do the job using external scripts but I have plenty of false errors because of the overload of the zabbix server.

Do you have an idea of how to do that more natively ?

What I CAN'T do:
- Count the number of hopes because main and backup lines have the same hopes number.
- Ping a hope, because it's impossible
- Install the zabbix agent or do something on a computer or a server on the remote sites

To be clear: everything have to be done localy.

On zabbix 2.0.4. No other linux servers.

For the main line we use something like : main.site.domainName
For the backup line : backup.site.domaineName

$1 = destination
$2 = hopes
$3 = main.site.domainName

 result=""
        result=$(traceroute $1 -m $2 -w 10 -q 1 )
        result2=""
        result2=$(echo $result | grep $3)

        if [[ -z $result2 ]]
        then
                #echo -e "NOK \n\n $result"
                echo 1
                return 1
        else
                #echo -e "OK \n\n $result"
                echo 0
                return 0
        fi

Example:

Network on the main line:
traceroute to aa.bb.cc.dd, 4 hops max, 40 byte packets using UDP
1 name1 (ip) 0.781 ms 0.742 ms 0.694 ms
2 name2 (ip) 2.284 ms 2.294 ms 2.865 ms
3 name3 (ip) 20.439 ms 20.193 ms 20.235 ms
4 main.site.domainName (ip) 20.218 ms 20.210 ms 20.211 ms

Network on the backup line:
traceroute to aa.bb.cc.dd, 4 hops max, 40 byte packets using UDP
1 name1 (ip) 0.781 ms 0.742 ms 0.694 ms
2 name2 (ip) 2.284 ms 2.294 ms 2.865 ms
3 name3 (ip) 20.439 ms 20.193 ms 20.235 ms
4 backup.site.domaineName (ip) 20.218 ms 20.210 ms 20.211 ms

The result will depend of the line 4. If the $3 is not find -> ERROR

Well, no motivation or idea ?
