The present invention relates to a method for distributing routing information for redundant connection. The method is implemented in hierarchical IPv6 Internet protocol (IP) networks comprising a plurality of different autonomous systems (AS) which use a border gateway routing protocol (BGP-4) to communicate, which protocol does not allow routing sessions to be established automatically, which prevents multi-provider services from being created. The method of the invention makes it possible to create multi-provider services in the networks discussed above by using the BGP-4 protocol established by the current standards and technologies. This makes it possible to increase services offered by the providers.
