ip rip display For CoreB uilder 9000: Applies to Layer 3 switching modules only.
Displays information about the Routing Inform ation Protocol (RIP)
interfaces on the system. RIP is one of the IP Interio r Gateway Protocols
(IGPs). When RIP is enabled, the system dynamically co nfigures its routing
tables.

Important Considerations
■The output for this display differs according to platfor m.
■The first line in the output (the status line) indicates whether IP routing
is enabled:
■For the CoreBuilder 9000 Layer 3 module, it also indi cates whether
Internet Control Message Protocol (ICMP) router discovery is
enabled on the system.
■For the CoreBuilder 3500, IP interface options (such as ICMP router
discovery) appear under “ip interface detail” earlier in this chapter
and are set on a per-interface basis. The rest of the output contains
more RIP interface information.
■The four available RIP modes are as follows:
■Disabled — The system ignores all incoming RIP packets and does
not generate any RIP packets of its own.
■Learn — The system processes all incoming RIP pa ckets, but it
does not transmit RIP updates.
■Advertise (3500 and 9000 only) — The system b roadcasts RIP
updates, but it does not process incoming RIP packets.
■Enabled (3500 and 9000 only) — The system s broadcasts RIP
updates and processes incoming RIP packets.
■An advertising router sends a RIP message every 30 seconds with both
the IP address and a metric (the distance to the destination from that
router) for each destination. Each router through which a RIP packet
must travel to reach a destination equals one hop.
