Unable to use router IP as Gateway

Hi

I’ve got 2 routers, linked to each other via vlans
router 1: network 192.168.88.0/24, this is also the Gateway to the the Internet
router 2 :network 192.168.89.0/24

I’ve can ping between the 2 routers on all their addresses
I’ve been able to set up the route to be able to ping an address on network 192.168.88.0 from route 2
The issue I have while trying to replicate the same on router 1, the routes gateway is always unreachable even though the address is 192.168.88.1

Router 1 Addresses

ADDRESS NETWORK INTERFACE
;;; defconf
0 192.168.88.1/24 192.168.88.0 Gigabit Bridge
1 192.168.89.254/24 192.168.89.0 VLAN_CAM_50
2 D 100.118.206.31/26 100.118.206.0 5G Upstream
3 192.168.88.1/24 192.168.88.0 VLAN_GEN_10 [/size]

When I try to add the route for the network to 192.168.89.0/24 using the gateway 192.168.88.1 the route is unreachable even though the ip i’m using is for router 1

Thanks

You cannot have multiple physical networks using the same subnet, the ‘Gigabit Bridge’ and VLAN_GEN_10 interfaces have the same address and subnet.

You may be suffering from https://xyproblem.info/, a diagram of what you are trying to achieve would be helpful.

Yes, we are not interested in how you think you should configure your router but much more interested in the requirements.
You clearly have something in mind but have not communicated it.

a. identify all the user(s)/device(s) / groups of users and devices / including external and local users / including admin
b. identify all the traffic flows they should be able to accomplish.

Diagram helps provide context on what equipment is involved, what ISps are involved and what you think you need to do in terms of connecting ports and subnets etc…
