Dear admin,

One day I was in big problem because the BGP service fails after MA5680T R52 upgraded to R62SPC100.

I put it to Huawei support website for necessary help &  got below solution which saved my life actually.

Again thanks Huawei team.

 

Solution

Currently, the system cannot control whether BGP packets are permitted. The only method is to

modify the VLAN attribute of BGP traffic streams to QinQ. After modification, the MA5680T

transparently transmits VLAN traffic streams.

1. Delete traffic streams carrying the BGP service. The following uses service port 2 with

VLAN 224 as an example. 

#undo service-port 2

2. Modify the attribute of VLAN 224 to QinQ. 

#vlan  attrib   224  q-in-q

3. Create traffic streams with QinQ VLAN 224 and tag-transform transparent. 

#service-port 2 vlan  224 gpon  0/1/0 ont 1 gemport  130 multi-service  

user-vlan   224 tag-transform  transparent  

#service-port 2 inbound traffic-table index 11 outbound traffic-table index 11

After modification, the BGP service is functional and the fault is rectified.  

You have a great success story keep it up ............

excellent...
