Customer want use VPLS kompella with BGP Auto-discovery feature between Huawei S5700HI (V200R005C00SPC500) and Cisco ISR 4451 (version 15.5),but after configuration, customer found that the VPLS not working.
The topology as bellow；
172.16.32.2 is Huawei S5700.
172.16.21.1 is Cisco ISR4451
The IGP is IS-IS.
N/A
Handling Process
1 check the IGP configuration and the status.--normal
2 check the BGP configuration and status------normal
3 check the VPLS status.-----abnormal
Check the Vpls configuration:
Huawei S5700:

After check the configuration, we found some feature not match between Huawei and cisco.
Solution:
Change the configuration both from the Huawei and cisco.

Sometimes Huawei and cisco use the difference feature even if it’s same protocol, we need analysis both device function, then find the differences and similarities.
