www.dell.com | support.dell.com This first RIP version does not support VLSM or CIDR and is not widely used. RIPv2 RIPv2 adds support for subnet fields in the RIP routing updates, thus qualifying it as a classless routing protocol. The RIPv2 message format includes entries for route tags, subnet masks, and next hop addresses. Another enhancement included in RIPv2 is multicasting for route updates on IP multicast address 224.0.0.9. Implementation Information FTOS supports both versions of RIP and allows you to configure one version globally and the other version or both versions on the interfaces. The C-Series and E-Series both support 1,000 RIP routes. Table 39-1 displays the defaults for RIP in FTOS. Table 39-1. RIP Defaults in FTOS Feature Interfaces running RIP RIP timers Auto summarization ECMP paths supported Default Listen to RIPv1 and RIPv2 Transmit RIPv1 update timer = 30 seconds invalid timer = 180 seconds holddown timer = 180 seconds flush timer = 240 seconds Enabled 16 Configuration Information By default, RIP is disabled in FTOS. To configure RIP, you must use commands in two modes: ROUTER RIP and INTERFACE. Commands executed in the ROUTER RIP mode configure RIP globally, while commands executed in the INTERFACE mode configure RIP features on that interface only. RIP is best suited for small, homogeneous networks. All devices within the RIP network must be configured to support RIP if they are to participate in the RIP. Configuration Task List for RIP • Enable RIP globally on page 785 (mandatory) • Configure RIP on interfaces on page 786 (optional) • Control RIP routing updates on page 786 (optional) 784 | Routing Information Protocol (RIP)
