ABSTRACT:
Transmitting routing information includes sending first and second messages from a router. The first message includes a digest of the routing information using a first authentication key and a first sequence identifier. The second message, which is sent after the first message, includes a digest of the routing information using a second authentication key and a second sequence identifier that is earlier in a sequence than the first sequence identifier.
