How to register a route from a remote office through VLAN?

Question

network hardware

Hello! "We have" such a network.

The problem is in routing from RouterC to RouterA. Ping-timeout.
At the same time, the connection (pings, etc.) from RouterA to RouterC is all good
. Everything is fine from RouterA to RouterB and back.
There is someone here who can prescribe the route using the above "network", if you need any additional information, I'll post it. Thanks in advance!.

For end-to-end traffic forwarding, I would generally use mangle
