Hi
1. To have dual ISP, 1 as active and 1 as standby you’ll need to use IP SLA with static route tracking.
To give you an example, let’s assume IP of ISP1 router is 192.168.1.1 and connected to your router on interface f1/0, and IP of ISP2 is 192.168.5.1 and connected to your router on interface f1/1, the config will looks like:
ip sla 10
icmp-echo 192.168.1.1 source-interface FastEthernet1/0
threshold 2
frequency 3
ip sla schedule 10 life forever start-time now
track 10 ip sla 10 reachability
ip route 0.0.0.0 0.0.0.0 192.168.1.1 track 10
ip route 0.0.0.0 0.0.0.0 192.168.5.1 10
2. What do you mean by how to connect? You’ll need to have an interco subnet and on ASA you’ll have a default route going to the IP on your router within this same subnet.
3. Same way as previous point with an interco subnet. On your switch you’ll have a default route going to ASA inside interface.
4. You’ll need to configure the port on which the switch is attached as trunk with the specific vlan like:
interface gx/x
switchport mode trunk
switchport trunk allowed vlan 2
Hope that answers your question

Hey Francesco Special Thanks for your Concern and sorry for my late reply
1. Is there I have to configure NAT on ASA firewall for the access of internet or just i need to add default route ?
2. Is there any configuration i have to apply for inside interface of ASA so the ASA accept the traffic from Core switch ?
