Hi.... U didn't mention any ip address as well as interfaces
which r used to connect routers.
R1(s1/0)------(S1/0)R2 (S1/1) -------(S1/0)R3------- server1
! ! ! 10.1.1.1
! ! ! 10.1.1.10
! ! !
PC1 PC2 Server2
13.1.1.1 12.1.1.1 11.1.1.1
13.1.1.10 12.1.1.10 11.1.1.10
Note: First one IP address & second default gateway.
R1
s1/0 - 1.1.1.1
R2
s1/0 - 1.1.1.2
s1/1 - 2.2.2.1
R3
s1/0 - 2.2.2.2
I configured RIPv2 on all router & its working fine. Now i
can access each & every user & server from anywhere in the
network.
Point is that, u want to configure ACL, so that it will meet
ur requirements.
As u mention, "implemnt access list on the r3 router in such
a way that user from r1 can access only one server"... ok i
m goin to block user from R1 to access "server1"
Create Standard ACL -
R3#conf t
R3(config)#access-list 5 permit 12.0.0.0 0.255.255.255
R3(config)#access-list 5 deny any
Apply ACL -
R3(config)#interface fastEthernet 0/1
R3(config-if)#ip access-group 5 out
Router(config-if)#^Z
See the sh output -
Router#sh access-lists
Standard IP access list 5
permit 12.0.0.0 0.255.255.255 (4 match(es))
deny any (3 match(es))
