I have a three Routers that connect to a three VLANs.
Router A connect to VLAN2
Router B connect to VLAN3
Router C connect to VLAN4
Router A, Router B and Router C is configured with a static route and thery are supplied by the third party
We can not change the setting to EIGRP
The traffice of VLAN2,VLAN3 AND VLAN4 are passed to VLAN5
VLAN5 are connected to a firewall.
(Please take a look for the attachement)
How can I set the switch?
If you do not have a default gateway, you cannot communicate with anybody.
That network will be isolated. You need to give a default gateway so that
the router can communicate with other devices.
With regard to the second question, you can configure access-list on the
switch to block communication between the banks.
access-list 101 deny ip 192.168.1.0 0.0.0.255 192.168.2.0 0.0.0.255
access-list 101 deny ip 192.168.1.0 0.0.0.255 192.168.3.0 0.0.0.255
access-list 101 permit ip any any
access-list 102 deny ip 192.168.2.0 0.0.0.255 192.168.1.0 0.0.0.255
access-list 102 deny ip 192.168.2.0 0.0.0.255 192.168.3.0 0.0.0.255
access-list 102 permit ip any any
access-list 103 deny ip 192.168.3.0 0.0.0.255 192.168.1.0 0.0.0.255
access-list 103 deny ip 192.168.3.0 0.0.0.255 192.168.2.0 0.0.0.255
access-list 103 permit ip any any
