Re: Cannot ping secondary ip address

I cannot ping PC 10.202.2.30 from the other subnet.

 

Questions to address the problem :

 

What is this device and how this is connected to network ?

 

interface GigabitEthernet0/1  - This port connected to Switch? if so what VLAN ?

 

we need to know your network topology what all the device involved between 10.202.2.30 to 10.202.2.1

Re: Cannot ping secondary ip address

Hello

From the "other side" does the rtr have route(s) for those secondary prefixes?

sh ip route
sh arp
