An enterprise needs to improve reliability of its campus network, to ensure non-stop services.
The network reconstruction includes:
1. Replace stand-alone MA5200Gs with ME60_1 and ME60_2 that work in active/standby mode.
2. Replace the original aggregation switches with a stack consisting of S5700_1 and S5700_2. In addition, VRRP and BFD are configured on S5700_1 and S5700_2.
3. Eth-Trunk is configured between access switches and S5700_1/S5700_2.
However, after the network reconstruction is complete, some users cannot obtain IP addresses in peak hours.
