Hello,

I need to add a specific static ip route when a given condition exists in a script, adding the route is no problem, but checking and preventing multiple routes that are the same from being added to the routing table, is vexing me, and I am in need of some inspiration. I have searched the archives and really haven't come up with good answer to a question that has to have been asked and answered in the past. Can someone either point me towards the illusive thread, or post any examples checking for the presence of a specific route before attempting to add a route that is already in the table.

Thank you for your attention.

Thanks, this is helpful somewhat. Only problem is I can't hard code the dst-address and gateway so I made the adaption

:if ([:len [/ip route find dst-address=$DIST and gateway=$DHCPGW]] >0) do={:put "Do something} else={:put "Do nothing"}

Is it possible to do the route find based on a value of a variable?

I finally got it to work, this post is so if someone else is looking for a route checking solution, and unable to find help in the archives, maybe this will help.

###
# Variables
###
: local INTERFACE "DHCP Interface Name"
: local DESTINATION "xxx.xxx.xxx.xxx/xx"
: local DISTANCE "XX"
: local COMMENT "Anything you want to add to the comment of the route you add"
: local DHCPGW [ /ip dhcp-client get [/ip dhcp-client find where interface=$INTERFACE] gateway ]
###
# IF there is no default gateway on dhcpclient interface or if interface is disabled, then error
:if ([:len $DHCPGW] = 0) do={
:put "No gateway on $INTERFACE interface"
}\
else={
:if ([:len [/ip route find dst-address=$DESTINATION and gateway=$DHCPGW]] =0) \
do={:put "No route"
:ip route add dst-address=$CLOUD gateway=$DHCPGW distance=$DISTANCE comment=$COMMENT check-gateway=ping;
:ip route add dst-address=$DESTINATION gateway=$DHCPGW distance=$DISTANCE comment=$COMMENT check-gateway=ping
}\
else={:put "Route Found"
}
}
