Symptom 1: Fail to configure Layer 2 VPN on the VLAN interface.
Solution:
Check to see if MPLS/BGP VPN, multicast, or VLL is enabled on the VLAN
■
interface. Because you cannot perform Layer 2 VPN configuration on a VLAN
interface if MPLS/BGP VPN, multicasting, or VLL is enabled on it.
Check to see if the VLAN is a Super-Vlan or a Sub-Vlan. You can perform the
■
Layer 2 VPN configuration only on common VLAN interfaces.
Symptom 2: Fail to ping the peer from one end of a Martini MPLS L2VPN
connection. The VC is down and the Remote value is invalid.
Solution:
VC state being down indicates the encapsulation types or VC IDs of the two
■
ends are not the same. Make sure the interface types (Access or Trunk) of the
two PE interfaces and the VC IDs of the two ends are consistent.
As for the invalid Remote value, make sure you have configured the Remote
■
parameters and the peer addresses correctly.
Symptom 3: Fail to ping the peer of a Kompella MPLS L2VPN connection. The
Connection is down and the VPN value is null.
Solution:
VPN value being null indicates the VPN is configured incorrectly. Make sure the
■
VPN configurations (such as RD) of the both ends are consistent, and the
connection configurations of the two CEs on both ends are correct.
