How RIP Operates on the Device
NOTE
Cisco 500 Series Stackable Managed Switch Administration Guide
The switch supports RIP version 2, which is based on the following standards:
• RFC2453 RIP Version 2, November 1998
• RFC2082 RIP-2 MD5 Authentication, January 1997
• RFC1724 RIP Version 2 MIB Extension
Received RIPv1 packets are dropped.
Enabling RIP
Enabling RIP
• RIP must be enabled globally and per interface.
• RIP can only be configured if it is enabled.
• Disabling RIP globally deletes the RIP configuration on the system.
• Disabling RIP on an interface deletes the RIP configuration on the specified
interface.
• If IP Routing is disabled, RIP messages are not sent, but when RIP
messages are received, they are used to update the routing table
information.
RIP can only be defined on manually-configured IP interfaces, meaning that RIP
cannot be defined on an interface whose IP address was received from a DHCP
server or whose IP address is the default IP address.
Offset Configuration
A RIP message includes a metric (number of hops) for each route.
An offset is an additional number that is added to a metric to affect the cost of
paths. The offset is set per interface and, for example, can reflect the speed, delay,
or some other quality of that particular interface. In this way, the relative cost of the
interfaces can be adjusted as desired.
It is your responsibility to set the offset for each interface (1 by default).
