I cannot ping PC 10.202.2.30 from the other subnet.

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

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

Hello
10.202.2.30 3 4439.c457.af7a ARPA GigabitEthernet0/1 <--reachable vai your gig0/1 interface
so where are you trying to connect to this ip from, what other subnet?
Does that other device have a route to 10.202.2.0/27

I tried to ping it from a pc in 10.202.0.1/23 subnet, which is also connected on same interface.
Thanks.
