i need this for 1.x and 2.x

access-list 101 permit ip 10.10.1.0 255.255.255.0 10.10.3.0

255.255.255.0 access-list 101 permit ip 10.10.1.0 255.255.255.0 10.10.4.0 255.255.255.0 access-list 101 permit ip 10.10.1.0 255.255.255.0 10.10.5.0 255.255.255.0

but do i need ?

access-list 101 permit ip 10.10.3.0 255.255.255.0 10.10.1.0

255.255.255.0 access-list 101 permit ip 10.10.4.0 255.255.255.0 10.10.1.0 255.255.255.0 access-list 101 permit ip 10.10.5.0 255.255.255.0 10.10.1.0 255.255.255.0

also

i have to subnets inside clients and servers my routing inside is configure for network 10.0.0.0, would it be better to narrow it down to 10.10.1.0 10.10.2.0 10.10.3.0 10.10.4.0? thanks
