Hi i have attahced diagram.

Thanks and Regards,

Hi,

I am not clear with your questions..

1.Are you trying to say that, if the E3 link in down, do you want to route the packet from 7609-01 to other network via your E1 link ??

2.Can i say that currently all your traffic from 7609-01 router to other network is going via firewall then 7609-02 router ??

If you are saying yes for the first question, then we need to implement TRACK based routing with IP SLA.

Hi what u r saying is correct.

1.if E3 link down means I want to route the packet via e1 link in cisco 7609-01

2. yes

Now what I am actually doing is I am manually adding routes via E1 link if E3 link is down. I am unable to use metric. Since we can use metric if firewall is going down. But for me routing has to be diverted only when E3 link is failure.

Hi,

No probs.. we can make it happen by configuring track based routing.

Find the config for your request

ip sla monitor 6
type echo protocol ipIcmpEcho source-ipaddr
frequency 300
!
ip sla monitor schedule 6 life forever start-time now

track 123 rtr 6 reachability

ip route 10.31.160.0 255.255.224.0 10.19.250.11 track 123
ip route 10.31.160.0 255.255.224.0 100

hi,

i am unable to use ip sla command

router(config)#ip s?
sap         security     slb  source-route  ssh
sticky-arp  subnet-zero.

how to configure slb command

Hi,

Your current IOS is not supporting to configure IP SLA.

You need to have the ADVANCED ENTERPRISE / ADVANCED IPSERVICE / ADVANCED SECURITY IOS in your router.

Can you paste the output of the "sh version" in your 7609 routers.

Sorry, but your topology is not that clear with the IP addressing schemes and the requirements stated.

But i am guessing that you need the E1 as back up for E3, and in that case you need the 7600's to talk to each other over a link with a protocol, any FHRP can do the job.

It doesnt matter how the firewall behaves, but should support routing.

Please post more details.

Sir,I am attached herewith details.

cisco 7609-01 ip address 10.19.250.7

Firewall ip address-10.19.250.11

cisco 7609-02 ip address 10.34.0.249
