Hi GS,

Is these 2 same?

As I understand they are the same and this single command makes things easy
for us.

1.

!
interface Ethernet 0/0
ip address 10.10.20.1 255.255.255.0
ip address 192.168.1.254 255.255.255.0 secondary
ip access-group FILTER in
!
ip access-list standard FILTER
 permit 10.10.20.0 0.0.0.255 any
 permit 192.168.1.0 0.0.0.255 any
!
