IP Configuration: RIPv2
How Rip Operates on the Device
Cisco 350, 350X and 550X Series Managed Switches, Firmware Release 2.4, ver 0.4
The following illustrates the configuration of the metric offset for various interfaces, based on
port speed.
Configuring the Offset (Based on Port Speed)
Router rD can send data to rA via rB or rC. Since rC only supports Fast Ethernet (FE) ports,
and rB supports Gigabit Ethernet (GE) ports, the path cost from router rD to router rA is higher
via router rC (additional 4 to the cost path) as opposed to the path via router rB (additional 2 to
the cost path), Therefore, forwarding traffic via routing rB is preferred. To achieve this, you
configure a different offset (metric value) on each interface based on its line speed.
See Offset Configuration
Passive Mode
Transmission of routing update messages over a specific IP interface can be disabled. In this
case, the router is passive, and only receives the updated RIP information on this interface. By
default, transmission of routing updates on an IP interface is enabled.
See RIPv2 Settings for more information.
