How to configure Internet routing together with inter-vlan on an L3 switch?

Question

Network routing

Good day to all!
There are Extreme Networks L3 switches. Enabled routing between VLANs (enable ipforwarding). In these switches, ports can be tagged (similar to Trunk) and untagged (similar to Access).
Imagine a (spherical in vacuum) structure that consists of a main switch (MC), two secondary switches (K1, K2), a workstation (RS) and a network printer (P). Port 1 of the GC is connected to port 1 of K1, port 2 of K1 is connected to the workstation. Port 2 of the GC is connected to port 1 of K2, port 2 of K2 is connected to a network printer:

ГК(1) - (1)К1(2) - РС
ГК(2) - (1)К2(2) - П

Workstation IP address 192.168.1.2/24, gateway 192.168.1.1.
Network printer IP address 192.168.2.2/24, gateway 192.168.2.1.
There are two VLANs on the GC: vlan 10 "Hosts" (port 1 tagged) with IP address 192.168.1.1 and vlan 20 "Printers" (port 2 tagged) with IP address 192.168.2.1.
K1 has one VLAN: vlan 10 "Hosts" (port 1 tagged, port 2 untagged) without an IP address.
K2 has one VLAN: vlan 20 "Printers" (port 1 tagged, port 2 untagged) without an IP address.
It is necessary to connect a router to the CC and configure the CC so that the network behind the router (Internet, intranet, etc.) is accessible from the workstation.
Let the router's internal interface address be 192.168.100.1/24. We connect the internal interface of the router to port 3 of the main switch. We create on the main switch VLAN 100 "GW" (untagged port 3) with an IP address of 192.168.100.2/24 and enable routing on this VLAN. Add default route for VLAN "GW" to 192.168.100.1. The routes on the main switch are as follows:

default          192.168.100.1 GW
192.168.1.0/24   192.168.1.1   Hosts
192.168.2.0/24   192.168.2.1   Printers
192.168.100.0/24 192.168.100.2 GW

As a result, the workstation does not see the router.
What did I forget or incorrectly set up on the GC to solve the problem?

Answer 1

The settings on the GC are correct. You need to configure the router: add routes on it to my networks that are behind the GC. But I don’t have access to the router, which means I either need to change the architecture, or put my router against the current router and the main switch.
