Kindly,have a look to the attached diagram;as well as to the Config provided from Devang!
i have 2 wireless connection from 2 different ISPs(ISPA;ISPB)ISP A Terminate link at R1;ISPB Treminate link at R2;i want to achieve the following setup:if the first Link(ISPA)fail the second link (ISPB) TAKE OVER.R1 ITS PRIMARY;R2 ITS SECONDERY.e.g continuous internet access in case on of link goes down
How can i CONFIGURE like this setup?can i do load Balence?
Config like this:
*****************
active router(R1)
*****************
interface fa0/0
ip address 10.10.100.2 255.255.255.255.0
no ip redirects
ip nat inside
standby 10 priority 105 preempt
standby 10 name HSRP1
standby 10 ip 10.10.100.1
standby 10 track Fa 0/1
!
ip nat inside source list 1 interface fa0/1 overload
access-list 1 permit 10.10.100.0 0.0.0.255

This config looks OK. Did you test it on your network?
In this next scenario you route some of your VLANs to R1 with R2 as backup and some VLANs to R2 with R1 as backup. Notice you now have 2 virtual interfaces:
*****************
router(R1)
*****************
interface fa0/0
ip address 10.10.100.1 255.255.255.255.0
stabdby 10 preempt
standby 10 priority 120
standby 10 ip 10.10.100.3
standby 20 ip 10.10.100.4
Router(R2)
******************
interface fa0/0
ip address 10.10.100.2 255.255.255.255.0
standby 20 preempt
standby 20 priority 120
standby 20 ip 10.10.100.4
standby 10 ip 10.10.100.3

Hi!
1)on both routers do i need static route point my network to the outside interface?
2)on the switch do i need defautl route point to the virtual interface?

What does your switch configuration look like?
Do you have the routers in a separate VLAN?
02-19-2007 03:02 AM
HI
No in same Vlan;i meant in the previous post:
1)default route from the switch to the virtual ip address
2)static route from from both routers to outside interface(real ip address on both routers)

Yes, what you describe is right.
The two routers also need to communicate with each other so they can exchange HSRP protocol messages.
02-19-2007 04:12 AM
the 2 routers & also the switch on the same segment!so why do i need to configure Static/default route?
02-19-2007 04:23 AM
If you have a single VLAN on your switch, then you do not.

There is no substitute for testing.
Configure your routers and test. If you have problems, use troubleshooting commands (mainly show ..., Or debug) and post the output on this forum.
