Re: Monitoring QoS

[G.W. Boschloo]

Shaun,

What you can do is testing the config with some testing tools like Netperf
(http://www.netperf.org/) or Qcheck
(http://www.netiq.com/products/Network_Performance/Qcheck.asp). These tools
will stress your config!!!

I'm studying Bridging and I was wondering how important this technology is.
Not in terms of knowing it for the test but I was wondering how much it is
used in the real world(using a router as a bridge). With dedicated switches
becoming inexpensive would you find this in much use anymore(other than
maybe translational bridging)? Any enlightenment would be appreciated.

RE: issues with HSRP

[Gerwin Boschloo]

Nonsense, the routers do not look in each others config to get HSRP working.
When HSRP is working, it checks to see if the primary router is online, in
your case it checks to see if the primary is up and running. When the
primairy fails it takes over the "shared"  address.nothing more (nothing
less). So when you virtual ip adres changes to the other blade, the other
config is used.

Oh when VLAN 1 was shutdown, HSRP will never use that interface.in
fact...HSRP will not be running on that interface.

Be aware that in a 6006 with MSFC's both MSFC's are online (also when 1
supervisor engine is switched off) so when you are bridging VLANS.take
care of the spanning tree.

Subject: issues with HSRP


Greetings

I implemented HSRP on my Catalyst 6006 w/ redundant Supervisor/MSFCs.
 I did a failover test - and it performed well - the redundant Supe
failed over and everything seemed to work fine.

However, when the promeary Supe came back online - some things did
not work right.  Mainly, bridging of LU6.2 traffic failed.

I called Cisco, and they said that with HSRP, both router configs
must be the same (in my case, VLAN 1 was shutdown on one of the
routers).  

Does anyone have any insight on this?  Do the router configs have to
be EXACTLY the same - line by line?  Does anyone know of any tools to
sync the configs. (I have just started playing with resource manager
essentials).

RE: VLAN Trunk traffic question

[Gerwin Boschloo]

I don't think so. A trunk type is just a tag type and has nothing to do with
the traffic inside it. When you configure VLAN's, you split up your network
into broadcast domains. So I think that you will have less traffic on a
trunk than you have without the trunks. Beware that when you (in the router)
bridge between the VLAN's, the amount of traffic will be increased because a
broadcast on VLAN 1 will also appear in VLAN 2.so this broadcast will be
twice inside the trunk.

I hope this helps,

Gerwin

RE: EIGRP contiguous AS

[Gerwin Boschloo]

EIGRP and IGRP are both Interior Gateway Protocols that are used inside a
AS. Therefore, when you want to connect different AS'es, you need an
Exterior Gateway Protocol like BGP. Within BGP you are routing to different
AS'es therefore the AS'es should be unique.
 
Therefore: EIGRP AS 1      IGRP AS 50     EIGRP AS 1 will not work.

If I remember correct, AS numbers do not have to be contiguous unless if you
want automatic redistributing between EIGRP and IGRP.  If you have different
AS across boundaries then you will need to have to manually redistribute...

Subject: EIGRP contiguous AS 


I have an interesting question for the group, although 
it is not directly related to any of the current 
exams. 

Does an EIGRP AS have to be contiguous or can it be on 
two sides of an IGRP 'AS'. I note that the use of the 
term AS is a mis-nomer for both protocols, but... 

For example, does: 

EIGRP AS 1      IGRP AS 1      EIGRP AS 1 

pose a problem? 

Does: 

EIGRP AS 1      IGRP AS 50     EIGRP AS 1 

My belief is that it could work, but it breaks the 
concept of an AS and could lead to routing topology 
table problems. Any takers? 

(I'll be working with my team in the lab, but thought 
it was an interesting thought questions.) 

Nothing but net!

Sure it will work -- if you redistribute. This is where you will possible
see routing loops.

 You can also create a tunnel interface on both EIGRP routers and share
EIGRP info that way.  This way they will both look like they are directly
connected.  Here's a possible config for the tunnel:

 (e0) r1(s0) -(s0) r2(s1) -(s0)r3(e0)

r1 and r3 e0 interfaces are in the 172.16.0.0 address space
All serial interfaces are in the 192.168.0.0 address space
r1 and r3 are running eigrp
r2 is running igrp with someone else

r1:
int e0
ip address 172.16.2.1 255.255.255.0

int tunnel 0
ip address 172.16.1.1 255.255.255.0
tunnel source 
tunnel destination 


router eigrp 100
