With RIP
The following example describes how to configure IP on a Layer 3 switch with RIP
running on the loopback interface:
The other routers do not need static routes for 172.25.13.2/32, because the route
is advertised by RIP.
Auto-Negotiation
On devices with less than 20 ports, the two highest ports (e.g. ports 9-10 on
SG300-10P) cannot be configured with auto-negotiation.
