Cisco Catalyst 250 Series Configuration Guide

In the following figure, you must enable routing protocols on the Ethernet management port when the PC is
multiple hops away from the switch and the packets must pass through multiple Layer 3 devices to reach the
PC.
Figure 4: Network Example with Routing Protocols Enabled
In the above figure , if the Ethernet management port and the network ports are associated with the same
routing process, the routes are propagated as follows:
•
The routes from the Ethernet management port are propagated through the network ports to the network.
•
The routes from the network ports are propagated through the Ethernet management port to the network.
Because routing is not supported between the Ethernet management port and the network ports, traffic between
these ports cannot be sent or received. If this happens, data packet loops occur between the ports, which disrupt
the switch and network operation. To prevent the loops, configure route filters to avoid routes between the
Ethernet management port and the network ports.
