It may not matter, it just had me confused.
After some more thought, I think I may need to add custom rules anyway
since I want to bind ipsec to specific routing tables (VRFs), and it
seems that charon (or something, not sure what exactly) is not properly
binding to xfrm interfaces with SO_BINDTODEVICE, as it is not using the
proper source address once I disabled the add-route logic.
The problem we had with the 220 table is that it stole our management
traffic and put it on the IPSEC connection. I will investigate that further
since we should not have had any routes in the 220 table at that point.
Do you know if the routing rules are required to bind the ike and related
messages to an xfrm device?
