vsi router on stick

Hello,


I'm not sure about how to set up a vsi that ends in a subinterface (like if it was a router on stick with a vsi).

OSPF, MPLS and LDP are working fine.


I've trying to configure Vlanif for L3 and binding physical and subinterfacces to the vsi but the vsi doesn't goes up, or i can't see any mac. The only way that i get up the vsi and see some mac is like this configuration:


PE1:

interface XGigabitEthernet0/0/9
 description SW1
 port link-type trunk
 port trunk allow-pass vlan 69


interface XGigabitEthernet0/0/15
 description PE2
 port link-type trunk
 port trunk allow-pass vlan 8

 pwsignal ldp

PE2:

 port trunk allow-pass vlan 69


interface Vlanif69

But I can't ping 192.168.12.69 from PE2

Could you give me some advice?


Thanks a lot

Hi, friend!
I have reviewed your feedback. I think the feedback is incomplete. The suggestions are as follows:
1. Ping SW1 from PE-1 and check whether the ping succeeds.
2. Run the display vsi name xxx verbose command on PE-1 and PE-2 to check the VSI status.
3. Check whether PE-1 and PE-2 can ping each other.
4. Run the display vsi command on PE-1.

Hi,

1. Ping SW1 from PE-1 and check whether the ping succeeds.

interface Vlanif69
description TEST-MGMT
l2 binding vsi TEST-MGMT

To check if I ping SW1 I need IP in the same network:

[PE1]interface Vlanif 69
[PE1-Vlanif69]undo l2 binding vsi TEST-MGMT
[PE1-Vlanif69]ip add 192.168.12.50 24

[PE1-Vlanif69]ping 192.168.12.69

2. Run the display vsi name xxx verbose command on PE-1 and PE-2 to check the VSI stat

3. Check whether PE-1 and PE-2 can ping each other.

After analyzing the configurations you provided this morning and now, the VPLS has been established and the single-ended route is normal.
Check the routing table and forwarding table to check whether the routing table is normal.
