A5 - Using dynamic IP routing alternatively to manually configured
static routes (refers to example A6)
Instead of configuring static routes on Router 2 it is more comfortable to use the “dynamic IP routing” feature
to announce the routes of all Router network interfaces to each Router. For announcing the routing infor-
mation the protocols RIP or OSPF can be used.
Note
If dynamic routing is activated but e.g. only the industrial Routers of the machine networks
and the production network should participate, this can be done by assigning additionally a
password to the used Router information protocol (RIP or OSPF). The result is that only
the Routers with the same password exchange their routing tables. With this method you
can avoid that routing tables of the industrial networks will be announced also in an upper-
level corporate network.
Configuring dynamic IP routing
In this example the protocol RIP (Router information protocol) is set for dynamic IP routing. You can choose
alternatively the “newer” protocol OSPF (Open shortest path first). Both are working properly.
► Select menu Configuration → Network → IP routing→ Tab “Configuration”
Configure below described entries in the section Dynamic routing of the menu:
→ Configure the below described parameters for all Routers 1 and 2 and all used interfaces
Interfaces Router 1: LAN 1, LAN 2, WAN, Router 2: LAN, WAN
Type
RIP
Simple password
Free text
Active Interface
Activate the checkbox if the Router shall send the routing table to the LAN/WAN
port (other Routers)
