Dynamic Routing Problem

Thu Sep 17, 2020 6:38 pm

hello everybody
i have a problem with mikrotik routing .i have two router with no configuration except two ip on their interfaces.i implemented this scenario in reality and even in gns3 and i get same result in both. as you can see in the picture i did not add any static route .my question is why when i ping from pc-1 to external router i have no response and vice versa .i have implemented this scenario with all these subnets in cisco and it works fine but in mikrotik .i don`t know why it doesn't work ?
why external router cant answer the ip
there is a dynamic route which says that all 5.18073.0/24 should go through ether2 ? am i right
* default gateway of pc-1 is

Check your subnetting. Your "external" router sees the src address of 73.65/27 as a local address b/c it's in the range of 73.0/24.
This would also not work with Cisco.
Try adding a static route to your "external" router for 73.64/24 with gw=73.3 then it should work.
