VPLS with SDP "up down"

[raikone14]

I am trying to configure a simple vpls just to learn, I tried twice and always with the same result ;

Identifier Type AdmMTU OprMTU Adm Opr
-------------------------------------------------------------------------------
sap:1/1/3:111 q-tag 1518 1518 Up Up
sdp:22:111 M(3.3.3.3) Mesh 1518 1518 Up Down
===============================================================================

Any idea what can cause this please ?
I am using ldp + ospf, but doesnt work ...


sdp 22 mpls create
far-end 3.3.3.3
sr-ospf
path-mtu 1518
keep-alive
shutdown
exit
no shutdown
exit
customer 1 create
description "Default customer"
exit
customer 2 create
description "CUST_A"
exit
vpls 111 customer 2 create
stp
shutdown
exit
sap 1/1/3:111 create
exit

Is the LDP session up?

Post the output of

show service sdp 22 detail
show router ldp session 3.3.3.3 detail
show log log-id 99 asc | match 3.3.3.3 context all

[paramount]

Are you intending to use OSPF segment-routing instead of LDP for the transport tunnel? Assuming so, if not, just remove this from the SDP config (sr-ospf) and replace with ldp (if you have LDP interface enabled that is).

I change the sdp from "sr-ospf" to "ldp", and now it up up...
But I cant ping from one host to another....if both are in the same vlan,should I do anything more ?
thanks a lot.

Here the full configuration of the 3 routers:

Hi ok, the configs you pasted still have sr-ospf, so don;t think they are the up to date ones.

But good news that the SDP is up. NOw can you check:

show service id 111 base
show service id 111 sdp 22 (detail)

If all looks good, you can check a packet across it without using your own kit, though no reason why yours should not work - if both on same subnet and you are tagging them with VLAN 111 before the hit the SR.

So at one end:

oam mac-populate 111 mac 00:00:00:00:00:01

At the other end:

oam mac-ping service 111 destination 00:00:00:00:00:01 source 00:00:00:00:00:02

If all working, it should show one reply with a round trip time and the SDP it used.

Finally, you can now check the MAC table and you should see 2 MACs, one local and one learnt:

show service id 111 fdb detail.
