IGRP has a number of features that are designed to enhance
its stability, such as:
Holddowns
Split horizons
Poison reverse updates

HolddownsHolddowns are used to prevent regular update
messages from inappropriately reinstating a route that may
not be up.

Split horizonsSplit horizons are derived from the premise
that it is usually not useful to send information about a
route back in the direction from which it came.

Poison reverse updatesSplit horizons prevent routing loops
between adjacent routers, but poison reverse updates are
necessary to defeat larger routing loops.

Today, IGRP is showing its age, it lacks support for
variable length subnet masks (VLSM). Rather than develop an
IGRP version 2 to correct this problem, Cisco has built upon
IGRP's legacy of success with Enhanced IGRP.

Suppose we have 4 switches runing in VTP mode. So when i create a VLAN in Server Switch this VLAN info reflect in all other switch. So question is - A) Suppose i m practicing this scenario in BOSON software, When a create a VLAN in server switch n ADD ports of switch to that VLAN, the same number of ports of client switch also belongs to dat VLAN. For example - In switch A (Server mode), i create a VLAN 7 name Hyderabad & port number 1, 2 & 3 put into this VLAN. Another Switch B (Client mode), its also showing that port number 1,2 & 3 belong the same VLAN. How cud it possible... As we know, VTP share only VLAN configuration information. Cud anyone explain it please....!!!! B)Same thing, when i m practicing in PACKET TRACER 5.0, its only showing that VLAN configuration information is shared. No port information is shared at all. I can manually configure individual switch port to respective VLAN as our wish. Cud anyone explain it please..!!!
