The purpose of the Attach-bit is to accomplish inter-area routing. In other venders, the Attached-bit is automatically set when a router is configured as a L1|L2 router and has two adjacencies. When a L1 router receives a LSP with the Attached-bit set it is supposed to create a default route pointing toward the neighbor to provide a default path out of the L1 area. ISIS implementation has been fixed to support the above definition: Setting the Attach-bit is now the default behavior and we allow the user to turn it off. We will only set the Default Attach-bit when creating a L1 LSP, if we are a L1|L2 router and have a L2 adjacency up. When a L1 router receives a LSP with the Attach-bit set, we will create a default route pointing to the L1|L2 router as the nexthop. The default route will be removed if the LSP is received with the Attach-bit cleared. Signed-off-by: Lynne Morrison <lynne@voltanet.io> |
