The invention provides a user message processing method and device, and the user message processing method and device are applied to EDs in an EVI network. The method includes the steps of setting up class-II EVI channels facing towards a public router and at least one EVI VPN channel facing towards a VPN router in an assigned EVI embodiment, inquiring a VPN to which a user router protocol message belongs, if the corresponding VPN is inquired, conducting routing learning on the VPN, if not, conducting routing learning in a public domain, inquiring a VPN to which a user data message belongs when IP forwarding is conducted on the user data message, if the corresponding VPN is inquired, forwarding the user data message according to a VPN router forwarding list, and if not, forwarding the user data message according to a public router forwarding list. According to the method and device, a user is allowed to conduct more flexible programming in a private network of the user, and the user can set up different IP networks to meet the requirements of the user.
