ROUTING PROTOCOLS

TRIGGERED UPDATES

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.

ROUTE ADVERTISEMENT OF VLANS

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 VERSION 1 VERSUS RIP VERSION 2

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.
