5700HI--VPLS kompella bgp AD with cisco

Publication Date:  2017-09-27 Views:  344 Downloads:  0
Issue Description

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;


R1 172.16.32.2 is Huawei S5700.

R2 172.16.21.1 is Cisco ISR4451.

The IGP is IS-IS.

Alarm Information

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:

R1 Huawei S5700:

vsi VPLS201

 pwsignal bgp

  route-distinguisher 64500:10201

  mtu-negotiate disable

  encapsulation rfc4761-compatible

 

interface Vlanif201

 l2 binding vsi VPLS201

 

bgp 64500

  l2vpn-ad-family

  undo policy vpn-target

  peer 172.16.21.1 enable

  peer 172.16.21.1 advertise-community

R2 Cisco ISR 4451:

bridge-domain 201

 

l2 vfi VPLS201 autodiscovery

 vpn id 10201

 bridge-domain 201

 mtu 1546

 vpls-id 64500:10201

 rd 64500:10201

 route-target export 64500:10201

 route-target import 64500:10201

 no auto-route-target

 

router bgp 64500

 address-family l2vpn vpls

  no bgp default route-target filter

  neighbor IBGP send-community both

  neighbor IBGP route-reflector-client

  neighbor IBGP suppress-signaling-protocol ldp

  neighbor 172.16.32.2 activate

  neighbor 172.16.32.2 send-community both

  neighbor 172.16.32.2 suppress-signaling-protocol ldp

Root Cause

After check the configuration, we found some feature not match between Huawei and cisco.

Solution

Change the configuration both from the Huawei and cisco.

Suggestions

       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.
