Two provinces (enterprise networks), the local router in order to realize hot standby configuration NQA, the router to end should be how to write back to addressing and routing, if write static, because there are optical transceiver, among ports is not down, so you should not, specific and didn't want to understand how to operate, thank you Daniel for

CodePudding user response:

Line 1 -- local: - to end B
Line 2 - local: A1 - to end B1

For line 1, NQA monitoring B address, if can't, routing priority relegated to B
For line 2, NQA monitoring B1 address, if can't, B1 to routing priority down
So that you can realize the switch routing
