The next sequence shows an example of configuring the IP addresses and subnet masks for the
virtual router ports.
VLAN Routing RIP Configuration
Routing Information Protocol (RIP) is one of the protocols which may be used by routers to
exchange network topology information. It is characterized as an “interior” gateway protocol, and
is typically used in small to medium-sized networks.
A router running RIP will send the contents of its routing table to each of its adjacent routers every
30 seconds. When a route is removed from the routing table it will be flagged as unusable by the
receiving routers after 180 seconds, and removed from their tables after an additional 120 seconds.
There are two versions of RIP:
• RIPv1 defined in RFC 1058
– Routes are specified by IP destination network and hop count
– The routing table is broadcast to all stations on the attached network
• RIPv2 defined in RFC 1723
– Route specification is extended to include subnet mask and gateway
– The routing table is sent to a multicast address, reducing network traffic
– An authentication method is used for security
The 7000 Series Managed Switch supports both versions of RIP. You may configure a given port:
• To receive packets in either or both formats
• To transmit packets formatted for RIPv1 or RIPv2 or to send RIPv2 packets to the RIPv1
broadcast address
• To prevent any RIP packets from being received
• To prevent any RIP packets from being transmitted.
