The problem is I want to made communication between L3(3560G) to L3 switches with help of RIP.
I configured the same think but not got success, but my L3 to L2 (2960)are working fine in a same building.
Please find attached configuration files of L3, L2 and network diagram, and suggest me proper configuration in respect of same.
So my aim is made communication between both building users to each other.
Solved! Go to Solution.

Hi Akshay,
In that case,
Instead of assigning IP address on physical fiber ports, make them as dot1q trunk on both sides,
1. Create a new vlan x on both switches
2. create Interface vlanx on both switches and assign the ip addresses that you wanted to assign it on physical ports
3. advertize this interfaces in eigrp using network command
4. eigrp neighbor will come up
5. verify using sh ip eigrp neigh and sh ip route eigrp
6. the link that you configured will be multilayer link, means the layer 2 traffic will pass through using trunk and if some traffic requires to go to other vlan in other switch will be routed via eigrp on the same link
Hope this helps

Hi,
First of all, why you want to use rip ? You better be using eigrp ...
Create a routed link (fiber ports) between two switches, i believe you dont want to pass layer 2 traffic across both switches.
On Switch A
int gix/y
no switchport
ip address 10.100.x.y 255.255.255.252
On switch B
int gix/y
no switchport
ip address 10.100.x.z 255.255.255.252
On Switch A
router eigrp 100
network 10.100.0.0 0.0.255.255
network 10.100.x.y 0.0.0.0
no auto-summary
insert this command only if you have assigned IP to routed port other that 10.100 network
Write down the ip address not the network address e.g. if ip add is 10.2.3.1/30 use network "10.2.3.1 0.0.0.0"
On switch B
router eigrp 100
network 10.100.0.0 0.0.255.255
network a.b.c.e 0.0.0.0 Write down the ip address not the network address e.g. if ip add is 10.2.3.2/30 use network "10.2.3.1 0.0.0.0"
no auto-summary
Eigrp neighborship will come up
verify
using "sh ip eigrp neigh"
sh ip route
HTH

Hi Hitesh,
Ok, i'm ready to you eigrp insist of rip.
but i want to pass layer 2 traffic across both switches, so in that case the suggest configuration is perfect or need to do any changes.
Please suggest...

Not sure what is the problem but I do see some missing command
router rip
network 10.0.0.0
version 2
no auto-summary
BTW, which VLAN is on the common subnet (the fiber between the 3560 switches)?
