Egress IP documentation which covers dedicated vlans (additional network interfaces) does not explain the behaviors around routing table management. This came up when we tried to configure a dedicated vlan for Egress IP and ensure there is no asymmetrical routing.

Here is the document where I'd expect to find this information:
