实验指南
The workstations at Charlie Company are IP−based. They have static default gateways configured pointing to 25.100.61.3. Configure the network so that the workstations have uninterrupted access to headquarters_co, even upon failure of the charlie_1 or charlie_2 routers; charlie_1 should be the primary router.
If the charlie_1 or charlie_2 serial interface fails, ensure that the router is not the primary router.
