I cannot ping devices from one switch to devices from the other switch

warrior_x · ‎04-29-2021

Hi. I have a problem with pinging devices connected to two switches in the router on a stick model. Is something wrong? It is about ping between PC11 and PC7, for example. However, the ping between PC11 and Router4 is successful. The project is attached. Thanks in advance for the hints!

PC11's ip address is duplicate with Router G0/0.5 ip address

Router Terminal Message:

Router#%IP-4-DUPADDR: Duplicate address 192.168.50.1 on GigabitEthernet0/0.5, sourced by 00E0.F7A2.09CE

Assign another IP address to PC11, fill in the default gateway, and then you can ping each other

Hello
Please attached revised file.

The issue was you had PC 11 with a duplicating ip address of the gig0/1.50 on the rtr , plus all vlan 50 hosts had no default-gateway so the other hosts in the other vland couldnt reach them.
