Abstract Abstract
In a network comprising thousands of BGP peers exchanging millions of In a network comprising thousands of BGP peers exchanging millions of
routes, many routes are reachable via more than one next-hop. Given routes, many routes are reachable via more than one next-hop. Given
the large scaling targets, it is desirable to restore traffic after the large scaling targets, it is desirable to restore traffic after
failure in a time period that does not depend on the number of BGP failure in a time period that does not depend on the number of BGP
prefixes. In this document we proposed an architecture by which prefixes. In this document we proposed an architecture by which
