I have the first Cisco switch with the below settings:
C100G_3(config-if)# sh running-config interface e1/27
interface Ethernet1/27
ip address 192.168.25.1/24
no shutdown
C100G_3(config-if)# sh ip route
IP Route Table for VRF "default"
'*' denotes best ucast next-hop
'**' denotes best mcast next-hop
'[x/y]' denotes [preference/metric]
'%<string>' in via output denotes VRF <string>
192.168.23.0/24, ubest/mbest: 2/0

The second cisco switch has the below settings:
C100G_2(config-if)# sh running-config interface ethernet 1/27
interface Ethernet1/27
ip address 192.168.25.2/24
no shutdown
C100G_2(config-if)# sh ip route

'*' denotes best ucast next-hop
'**' denotes best mcast next-hop

*via 192.168.25.1, [1/0], 00:59:36, static
192.168.25.0/24, ubest/mbest: 1/0, attached

C100G_2(config-if)#
Both the switch are ISLd through the 1/27 ethernet port in each switch.
Both the switch can ping each other ip assigned to the 1/27 interface.
I have two node.
The first node is connected the first switch( interface Eth1/9/4 ) and has the below ip settings:
5 RoCE 25Gb/s active configured 192.168.23.13 192.168.23.1 255.255.255.0
The second node is connected the second switch( interface Eth1/11/4 ) and has the below ip settings:
5 RoCE 25Gb/s active configured 192.168.23.12 192.168.23.1 255.255.255.0
Can you let me know if we can ping both the nodes using this configuration

Hello,
no I don't think so. You are using the same address space on two sides of a layer 3 topology.
They could only ping each other if they were connected to the same switch.
What are you trying to accomplish ?

Hi George ,
We want to achieve unicat ping between the nodes (with ip 192.168.23.13 & 192.168.23.12) over a network which in a different subnet;i.e 192.168.25.x.
