The version of the device upgrades from VRP3.3-0330.13 to VRP5.30-23138005. The following configuration occurs:
"arp static 10.208.32.70 000a-e6e2-4ca0 vpn-instance OA vid 100
arp static 10.208.32.78 0800-46cc-0c8e vid 100

arp static 10.208.32.89 000a-e6e4-88a9 vpn-instance OA vid 100"
Some vpn-instance OA cannot be displayed. The user responds that PC of OA cannot be used. Disable undo arp-proxy enable and delete all configurations of arp static. Then the service is recovered.
For NE20 system procedure, when static ARP entries are added, the router first checks whether there are the same dynamic ARP entries according to IP and VPN. If there are the same dynamic ARP entries, add the outbound interface to new static ARP entries before deleting them. The stored static ARP entries include VPN and the outbound interface. The commands of static ARP of VPN and the outbound interface are not configured. Before VPN of static ARP is generated, check whether the outbound interface is null. If it is not null, VPN is not displayed. According to the information provided by the site, VPN of static ARP is stored in the system. However, the same dynamic ARP entries exist when adding static ARP entries. When the system adds static ARP entries, it adds the outbound interface to static ARP entries. These static ARP entries carry VPN and the outbound interface. When the outbound interface is null, VPN is not displayed. Actually, the stored static ARP entries are complete. The display of static ARP entries does not influence the service.
The router is not influenced when VPN of static ARP is not displayed. The abnormal service is caused by arp-proxy. The following solution is provided.
Delete ARP proxy of NE20.
Upgrade the version to NE20-VRP5.30-23138009 and patch. NE20-VRP5.30-23138009 is more stable than NE20-VRP5.30-23138005.
