After MA5200G VRP3.30-22xx upgrades MA5200G VRP3.30-23xx, VPNv4 neighbor and MPLS tag are normal. Route of VPN private network can be learnt, but static users of VPN cannot ping through other users' address of VPN and gateway.
1. Check BGP neighbor, VPNv4 neighbor and MPLS tag allocation and they are normal.
2. Check route of VPN private network and it is normal.
3. Check configuration file and find that related configuration of static-user is lost, re-configure related command as follows:
static-user 192.168.21.15 192.168.21.15 vpn-instance vpn interface Ethernet1/1/6.5 vlan 2001 detect domain-name vpn
Note: 23xx version needs designate vpn-instance when it adds VPN static-users.
4. Bind vpn-instance under user’s BAS interface.
pppoe-server bind virtual-template 1
5. The service recovers.
After MA5200G VRP3.30-22xx upgrades MA5200G VRP3.30-23xx, MPLS VPN configuration changes and MPLS VPN service does not communicate. In 23xx version, designate vpn-instance of static users and bind related vpn-instance under BAS interface.
