A computer-implemented method, comprising: initiating a not-via approach for creating and storing repair path information for a first link between a first network node and a second network node in a network, in which not-via addresses are assigned to each node in the network, a not-via address indicating that a packet addressed to a node having the not-via address is to be delivered to the node with that address not via a node which is also indicated in the not-via address; creating repair path information for the first link using the not-via approach by determining and storing a list of network nodes that form a not-via repair path from the first network node to the second network node; wherein the not-via repair path traverses the determined network nodes; wherein the not-via repair path does not traverse the first link between the first network node and the second network node; creating and storing (206, 208, 212) entries in a Forwarding Information Base, FIB, identifying not-via addresses for the network nodes that form the not-via repair path and that cause (a) packets directed to all addresses normally reachable through the first link to be encapsulated to the second node via the not-via repair path, (b) packets directed to a not-via address that is normally reachable through the first link to be encapsulated to the second node via the not-via repair path, unless the packets are directed to a not-via address that is in the list, in which case the packets are dropped; repeating the initiating, creating and storing the list and creating and storing entries for all other links of the first network node. initiating a not-via approach for creating and storing repair path information for a first link between a first network node and a second network node in a network, in which not-via addresses are assigned to each node in the network, a not-via address indicating that a packet addressed to a node having the not-via address is to be delivered to the node with that address not via a node which is also indicated in the not-via address; creating repair path information for the first link using the not-via approach by determining and storing a list of network nodes that form a not-via repair path from the first network node to the second network node; wherein the not-via repair path traverses the determined network nodes; wherein the not-via repair path does not traverse the first link between the first network node and the second network node; creating and storing (206, 208, 212) entries in a Forwarding Information Base, FIB, identifying not-via addresses for the network nodes that form the not-via repair path and that cause (a) packets directed to all addresses normally reachable through the first link to be encapsulated to the second node via the not-via repair path, (b) packets directed to a not-via address that is normally reachable through the first link to be encapsulated to the second node via the not-via repair path, unless the packets are directed to a not-via address that is in the list, in which case the packets are dropped; repeating the initiating, creating and storing the list and creating and storing entries for all other links of the first network node.
