Abstract

In one or more embodiments, an architecture is provided that may intercept a route update message and compare AS numbers of an AS path with a list of AS numbers known or inferred to be problematic. In one or more embodiments, the problematic AS numbers can be substituted with a local AS number such that loop detection checks enforced automatically on many networks do not discard the message and/or prevent connectivity between two disparate networks.
