hii
Here i am attached my Network Diagram.in this diagram i have shown that we are having Two valn and we are reqired HSRP so how it's possible and how it configure??

Just one more little thing..... if you are tracking another interface - you need to configure a decrement value, by default it's 10. So if you set the priority to 150 and track an interface, when that interface goes down - it decrements by that value = 150 - 10 = 140. The Default HSRP priority on an interface is 100....so the interface that is connected to the failed circuit still has the highest priority :o(

what format is your diagram in?

What you want to do is pretty straight forward.
R2 could be the active and R3 could be the standby. The HSRP or standby address should be the IP address, the PC's and Phones have currently as a default gateway. Then you give the interfaces their own IP address. Configure your group numbers, preempt & priority numbers - and you are good to go.

hii..
You are right.but ..
My Problem is in my R1(Main) router there is no. of sub interface, so i have to Put HSRP configuration to all Subinterface.? and is there R3 router connected through Trunk Port?? and is it also configure sub interfaces in R3 Standby Router.?

R3 is not in question?
You want to have 100% availbility from SW1 & SW2 to a layer 3 routing device = HSRP on VLAN 1 and VLAN 2 this is easy.
The connection between R2/R3 & R1 is something different - how do they connect?? over a serial connection?? I would run a dynamic routing protocol between R1/R2/R3 - use a specific /29 IP subnet between them.

ok ok so just i have to configure HSRP in first valn! and just R3 connected with Trunk Port ok ?..

I agree with you Andrew. I misread his diagram for I don't VLAN2 address on the switch. As you pointed out, the HSRP should take place for VLAN1 and VLAN2 ant its standby address would be used as gateway addresses

here i have to use layer 2 sw and inter-Vlan routing is there..can you send me configuration fo both R2 and R3 Router?
02-17-2009 09:07 AM
a sample HSRP config that you can modify on your layer 3 switches.
sw1
int vlan1
ip address 10.60.2.100 255.255.255.0
standby 1 ip 10.60.2.x
standby 1 prio 150
standby 1 preempt
int vlan2
ip address 10.60.5.x 255.255.255.0
standby 2 ip 10.60.5.y
standby 2 preempt
sw2
int vlan1
ip address 10.60.2.101 255.255.255.0
standby 1 ip 10.60.2.x
standby 1 preempt
int vlan2
ip address 10.60.5.z 255.255.255.0
standby 2 ip 10.60.5.y
standby 2 pri 150
standby 2 preempt
02-17-2009 09:10 AM
I would add one thing
standby x timers 1 3
The interfaces sends hellos every 1 second and considers the other side dead after 3 missed hellos - the failover time is 3 seconds. The default are 5 and 15 - the failover time is 15 seconds......in most networks this is to high, but.....

:-)...really nice. I just learned something.

;o)

Thank you for configuration but my main problem is we are using only Layer 2 Sw and is this (HSRP) possible with Router only??? we are not worried about Vlan but main thing is connecting R1 to R2,R3 with Serial (E1) Link. when R2 router link is broken then all my vlan traffic pass through R3 (stand by) Router To R1..?

The config supplied works in routers, just change the interface types.
if you want to track your serial interfaces the use:-
standby x track serial x/x
if your serial interfaces goes down, the LAN interfaces drops its priority and R£ takes over.
