IP/Route and IP/Adresses, the "Adddress List"

Thu Feb 22, 2024 7:04 pm

Working to copy the 2-router network described at
Code: Select all
 https://help.mikrotik.com/docs/display/ROS/IP+Routing
Connectivity is not what I expect: can't use Winbox from LAN 1 to reach Router 2; can't ping between the 10.10.10.0 and 10.10.55.0 subnets.
I find I'm not clear on some aspects of the Address List. For example, in a subnet between the routers (176.16.1.0) router 2 farther from the Internet is given 176.16.1.2 and that is used in router 1 as the gateway to the LAN on router 2. Adding an address to the Address List creates a dynamic entry in Route List in which the gateway is filled in with the interface specified for Address List and can't be changed to an IP. The example specifies the IP from a terminal, not the interface. In Winbox the configuration for IP/Route offers a pull-down list of interfaces in the field where an IP for a gateway is accepted. Is there a difference in function between choosing an interface (eth3) or an IP address?
This example uses a static route between the router on the 176 subnet. I assume that means there is no reachability information exchanged and that the IP/Address or Address List in router 1 needs to specify every subnet on the network for router 2. Correct?
Minor point: what does blue type mean for an item in the route list?
Here's the config from router 1:

Re: IP/Route and IP/Adresses, the "Adddress List"

Firstly, you don't need to have the LAN subnets of Router2 in the address list of Router1, you should remove them. Secondly, I don't see any 10.10.10.0 subnet that should be pingable. Thirdly, indeed there is a difference whether your gateway is a port or an address:
Such route has following special properties:
  • Unlike connected routes, routes with interface nexthops are not used for nexthop lookup.
  • It is possible to assign several interfaces as a value of gateway, and create ECMP route. It is not possible to have connected route with multiple gateway values.
(From MikroTik Wiki)

Lastly, the blue color on a route means it's not active. Given 192.168.2.0 and 192.168.55.0 are subnets of Router2, 10.10.55.1 is its gateway and 10.10.55.40 is its WAN address, the following configuration overall should be done:
Code: Select all
/ip address
remove [find network=192.168.2.0]
remove [find network=192.168.55.0]

/ip route
set [find dst-address=192.168.55.0/24] gateway=10.10.55.40
