NE40 operates VRRP port connected with PC, VRRP at NE40 is normal. PC can ping through the address of the interface, but cannot virtual address of VRRP. Version: VRP3.10-2226
1. Check NE40 configuration and check whether it opens ping of VRRP virtual address.
2. At NE40 capture packet with port mirror. Attached PC has sent virtual MAC of ARP request to VRRP virtual address, but NE40 responds ARP packet that is MAC address of the interface.
3. Check configuration. The interface uses ARP-PROXY. Close ARP-PROXY and the problem is solved.
Enable VRRP interface and open ARP-PROXY. When PC requests MAC of VRRP virtual address to NE40 (the main interface operates ARP-PROXY and the interfsce actually responds ARP request to PC), in fact PC learns MAC of NE40 interface. It cannot communicate with VRRP virtual address and cannot ping through it.
