•
PBB configurations on the BEBs are inconsistent.
•
The B-VLAN in the BEB is not created on the BCB, or ports connecting the BEB and BCB are not both
assigned to the B-VLAN.
Solution
To resolve the problem:
1.
Use the
display l2vpn
vsi
verbose
command to display the PBB configuration of the VSI.
{
If the VSI is not configured as a PBB VSI, configure the VSI as a PBB VSI.
{
If the VSI is down, use the
undo shutdown
command to bring the VSI up.
For more information about the
display l2vpn vsi
verbose
command, see
MPLS Command
Reference
.
2.
Use the
display l2vpn vsi verbose
command to verify that the VSI's PBB settings are consistent
across BEBs, especially the I-SID and B-VLAN settings.
PBB configurations on the BEBs should be consistent.
3.
Use the
display vlan all
command to verify that the following settings are configured on all BCBs:
{
The B-VLAN is created on each BCB.
{
All ports on the path between the BEBs are assigned to the B-VLAN.
4.
