Suppose the edge BGP speakers PE1, PE2,..., PEn know about a prefix P/m via the external routers CE1, CE2,..., CEm. If the edge router PEi crashes or becomes totally disconnected from the core, it is desirable for a core router "P" carrying traffic to the failed edge router PEi to immediately restore traffic by re-tunneling packets originally tunneled to PEi and destined to the prefix P/m to one of the other edge routers that advertised P/m, say PEj, until BGP re-converges. This draft proposes a BGP FRR scheme that relies on having the repairing edge router mirror the protected edge router forwarding table. The repairing edge router uses a locally allocated context label to identify the correct mirrored table.}, }
