You can reach interfaces that are directly connected on the Cisco routers.
It seems that static routing is not working, to be able to reach the networks connected on the ZS (LABS). So my suggestion is to enable RIPv2 on ETH00 of ZS and LAN interface of Cisco 1 (ask it from the netadmins).
Static routing on the CISCO 1, have this route:
ip route 192.168.0.0 255.255.0.0 192.168.0.1
I’m asked about activate RIPv2… I’m waiting…
