Routing case

Hello,

we have an online system used to provide our service to the customers, we used 2 cisco 3845 routers with

HSRP configured on both of them.

one router is the primary and the second is the secondary connection to provide redundancy.

there is Cisco ASA behind these two routers and there is a default route configured in this ASA to

route traffic to the virtual IP of these 2 routers.

we have a separate internet connection and we want to cancel it.

what we want to do is use the secondary router to provide internet to our intrnal LAN and still be a backup

for the primary router.

Primary Router:

interface GigabitEthernet0/1

ip address 3.3.3.1 255.255.255.192

standby 1 ip 3.3.3.2

standby 1 preempt

Secondary Router:

interface GigabitEthernet0/0

ip address 3.3.3.3 255.255.255.192

standby 1 ip 3.3.3.2

standby 1 priority 95

standby 1 preempt

Cisco ASA:

route outside 0.0.0.0 0.0.0.0 3.3.3.2

Online system:

ip address: 3.3.3.6

so what should we do?

Thanks

Re: Routing case

Hi Mahmood,

thanks for the reply, i forgot to mention the natting configurations configured in cisco ASA:

nat (inside) 1 0.0.0.0 0.0.0.0

global (outside) 1 3.3.3.7 netmask 255.255.255.255

the cisco ASA is connected to Cisco Core switch.

but i didn't understand your question about what ip address i'm going to use from internet?
