RE Configuration Exercise: BCSN

2000-12-22 Thread Dyland Desmarais 

I'm not sure if your doing this on actual physical equipment but if you
would refer to the figure 1-15 on page 43:
P1R1 can route to the subnet 192.168.1.65 (this is subnet 64, 65 is the
first available host, configured on P1R2 interface E0) through S0 and S1
(192.168.1.18, 192.168.1.34).
It can also access that subnet by routing through S0 on P1R3 (192.168.1.66)

As for the math, the show ip protocols command does not give the required
information needed to calculate the metric by hand ( i may be mistaken on
this so anyone please correct me if needed)

I am currently studying for the BCSN exam, have a question . . .
1. For those who have a copy of Cisco Press BCSN 
ISBN:1-57870-228-3:
Page 58 Step 12, Question: How many paths are in the IGRP routing table
to the 192.168.x.64 subnet?
Why are multiple paths to the subnet?

Answer: There are three routes to the 192.168.x.64 subnet in the routing
table. there are multiple paths 
in the routing table because they are all of equal metric (in this case,
the metric is 158350).

I don't understand how the author arrived with three routes to the
192.168.x.64 subnet. Also, the metric
= 158,350. I know the BW=64000 and time delay = metric/bw= 2.4742
seconds. How did they arrived with this metric of 158,350?


Thanx in advance . . .

Multicast addresses are SUPPOSED to be registered. I suppose some of that
has fallen by the wayside as all these new players rush in an d write their
applications to do whatever.  I checked the IANA database www.iana.org and
clipped a few of interest. Some we know and love. I was surprised by a
couple.


224.0.0.0 Base Address (Reserved) [RFC1112,JBP]
224.0.0.1 All Systems on this Subnet [RFC1112,JBP]
224.0.0.2 All Routers on this Subnet [JBP]
224.0.0.3 Unassigned [JBP]
224.0.0.4 DVMRP Routers [RFC1075,JBP]
224.0.0.5 OSPFIGP OSPFIGP All Routers [RFC2328,JXM1]

224.0.1.39 cisco-rp-announce [Farinacci]   wonder what this stuff is ;->
224.0.1.40 cisco-rp-discovery [Farinacci]

Cisco calls this "bi-directional PIM" guess I'll be doing some reading on
this soon.

224.0.1.47 telerate [Peng]   if this is the telerate I know and used to
hate, they have long since been subsumed by Bridge

224.0.1.48 ciena [Rodbell]   doesn't Cisco own a piece of these folks?

224.0.1.118 Tivoli Systems [Gabriel]

224.0.1.128 CNN [Lynch]   oh boy I can hardly wait!

224.0.6.000-224.0.6.127 Cornell ISIS Project [Tim Clark] didn't someone
say ISIS was dead?

Thanks Dyland,
The answer came from page 58, "p1r1#show ip route" output.
The three routes to 192.168.1.64 subnet are 192.168.1.50, 00:00:08,
serial2
   
192.168.1.18, 00:01:02, serial0
   
192.168.1.34, 00:01:02, serial1

___
  {100/158350}   
   00:02:12 seconds ?
