RIGGERED PDATES
Triggered updates occur whenever a router changes the metric for a route, and it is
required to send an update message immediately, even if it is not yet time for a regular
update message to be sent. This will generally result in faster convergence, but may also
result in more RIP-related traffic.

OUTE DVERTISEMENT OF
VLANs that are configured with an IP address, but are configured to not route IP, have
their subnets advertised by RIP with a metric of 16 (unreachable). To disable the
advertising of a subnet completely, you must unconfigure the IP address for the VLAN
using the following command:
unconfig vlan <name> ipaddress
RIP V 1
ERSION VERSUS
A new version of RIP, called RIP version 2, expands the functionality of RIP version 1 to
include the following:
• Variable-Length Subnet Masks (VLSMs)
• Next-hop addresses
Support for next-hop addresses allows for optimization of routes in certain
environments.
• Multicasting
RIP version 2 packets can be multicast instead of being broadcast, reducing the
load on hosts that do not support routing protocols.
