Link State Routing – Computing New Routes
... If a router crashes and comes back up later, it starts with sequence # 0. So the next packet will be rejected as being obsolete. To prevent this, the age is included in the LSP. ...

... because each edge is exponentially distributed with mean l/p. Since the graph is fully connected, each of the I nodes in i have a path to u. Therefore, the rate at which the messages travel from nodes in i to the node v is the sum of the rates along all these paths, lt.~. q Theorem 4. Let 1 be the n ...
