2 providers 2 vlan ubuntu server how?

Question

System administration

We have a software router on ubuntu, one network card looks inserted into the control switch, based on it vlan for the provider. Now the second provider has come in, made another vlan, registered an external ip for vlan. What is needed for normal operation? register 2 default gates with different metrics? or do I need to create 2 routing tables for each? I don't need balancing, I need the server to be available from 2 vlans at once, should I do a masquerade for both vlan-n at once? I heard that you need to create 2 routing tables in /etc/iproute2/rt_tables

Answer 1

policy routing is our everything
