|long reply thank u and i hope that ur finger tips are fine :D|
No worries, I've been working in IT for 15+ years and my typing skills are excellent. I can type 80+ wpm for quite long periods of time without tiring my poor old hands. My first response took about 2 1/2 minutes of my time to type out.
my Q. is If VTP is advertising the vlan 100 IP won't that cause a problem ????
I'm not sure I follow you. What is it you wish to advertise? As I understand VTP, all it does is advertise VLAN's across linked switches.
but let's assume that i have vlan 100 that's gonna participate in HSRP on 2 switchs
now u must give these vlans IPs one for each switch so on sw1 vlan 100 might have the ip of 192.168.1.1/24 and on sw2 the same vlan 100 will have another ip add. let's say 192.168.1.2/24
Why would you assign IP's? To what are you assigning the IP's?
As I stated in my first reply, you assign IP's to switches on the management VLAN, VLAN 1. All other VLAN's (ie: data VLAN's) get assigned to ports.
As I stated previously, we use VRRP with dual redundant core switches and their IP's are VLAN 1 (management VLAN).
Advertised default gateway = 192.168.1.250
(we use .250 as the DG in all our subnets).
The core switches are joined with an IST (inter switch trunk) which makes them redundant. The point of HSRP, as I understand it, we don't use it right, is the same thing, to provide redundancy. In our case, if Core 1 is running as the "DG" and it fails, the DG role moves automatically over to Core 2. The actual VRRP advertised DG address never changes from the client point of view.
Now if you're using cisco core switches I would presume they configure similarly using their proprietary cisco HSRP. However, I'm not sure you could do this on just any two switches and it seems to me, in order to work, your two switches would have to be joined by an IST and be advertising a 3'd IP like we do.
Just an FYI from me to you for future reference. You may want to try typing using proper capitalization, punctuation and grammar. Not doing so looks VERY unprofessional and makes it a lot harder to read. If you want to be seen as a professional, and be taken serious by professionals, you'll want to type like a mature, literate adult and not like a child.
If you look and compare, you'll see all my responses are a lot easier to read than yours are. That's because our brains are trained to see the capitalization and punctuation. Take it away and we have to slow down and start reading one word at a time.
