Hi There Tony

I think this could help

R3 Connect to the same Broadcast Segment with R2, in the 20.0.0.0/8 Network

R3(config-router)#do show run int l0
Building configuration...
                                             
Current configuration : 197 bytes
!
interface Loopback0
 ip address 10.1.0.1 255.255.255.0 secondary
 ip address 10.2.0.1 255.255.255.0 secondary
 ip address 10.3.0.1 255.255.255.0 secondary
 ip address 10.0.0.1 255.255.255.0
end

With this configuration, in the Router
R3(config-router)#do show run | b router rip
router rip
 version 2
 network 10.0.0.0
 network 20.0.0.0
 no auto-summary

RIP Version 1 always uses automatic summarization.

BB1-TS#3
[Resuming connection 3 to R3 ... ]
R3(config-if)#do show run int e0/0
Building configuration...
                                                               
Current configuration : 100 bytes
!
interface Ethernet0/0
 ip address 20.0.0.3 255.255.255.0
 ip rip send version 1
 half-duplex
end
BB1-TS#2
[Resuming connection 2 to R2 ... ]
R2#show ip route rip
R 10.0.0.0/8 [120/1] via 20.0.0.3, 00:00:26, FastEthernet0/0
R2#

If you are using RIP Version 2, you can turn off automatic summarization by
specifying the no auto-summary command.
R3(config-if)#no ip rip send version 1
R3(config-if)#router rip
R3(config-router)#auto
R3(config-router)#
BB1-TS#2
[Resuming connection 2 to R2 ... ] R2#

R2#clear ip route *
R2#show ip route rip
R 10.0.0.0/8 [120/1] via 20.0.0.3, 00:00:00, FastEthernet0/0

Disable automatic summarization if you must perform routing between
disconnected subnets.

When automatic summarization is off, subnets are advertised.

R3(config-router)#no auto
R3(config-router)#
BB1-TS#2
[Resuming connection 2 to R2 ... ]
                                                                
R2#clear ip route *
R2#show ip route rip
     10.0.0.0/24 is subnetted, 4 subnets
R 10.2.0.0 [120/1] via 20.0.0.3, 00:00:01, FastEthernet0/0
R 10.3.0.0 [120/1] via 20.0.0.3, 00:00:01, FastEthernet0/0
R 10.0.0.0 [120/1] via 20.0.0.3, 00:00:01, FastEthernet0/0
R 10.1.0.0 [120/1] via 20.0.0.3, 00:00:01, FastEthernet0/0

Hi Group,
I f I have to send concrete routes to my neighbor ,and not allowed to use
summary command.
Does this mean I cant use auto-summary command or ip summary interface
command?

Regards, Tony
