H-VPLS using MPLS in access

Sherif Atef Ahmed Ismail · ‎11-21-2011

Dears,

I would like your assistance regarding below plz

How to map EoMPLS PW from U-PE to N-PE to the VPLS network at N-PE

U-PE1 <----- MPLS -----> N-PE2 <-------- VPLS Network -------> N-PE3

I believe xconnect vc @ U-PE should match vfi vpn id @ N-PE as below, correct ?

U-PE

interface gi1/0

ip add 10.0.0.1 255.255.255.0

xconnect 10.0.0.2 99 encapsulation mpls

N-PE2

l2 vfi test manual

vpn id 99

neighbor 3.3.3.3 encapsulation mpls

neighbor 4.4.4.4 encapsulation mpls

Many Thanks

BR,

Hi Sherif,

I'm not sure that the ID has to match, I believe you are missing a neighbor statement on the N-PE2 towards the U-PE;

l2 vfi test manual

vpn id 99

neighbor 3.3.3.3 encapsulation mpls

neighbor 4.4.4.4 encapsulation mpls

neighbor 10.0.0.1 99 enc mpls

It seems a little odd that the U-PE xconnect IP is to a destination inside a subnet on the same interface, maybe you meant;

int gi1/0

xconnect 10.0.0.2 99 enc mpls

int gi1/1

ip add 10.0.0.1 255.255.255.0

mpls ip

The only reference I could find was from another different thread on this forum which referenced this;

Remember,

If you want to segment traffic. Use the xconnect on the SVI.

example

Vlan100 - customer A

Vlan 200 - customer B

l2 vfi 99 manual

vpn id 99

neighbor 1.1.1.1 encapsulation mpls

l2 vfi 98 manual

vpn id 98

neighbor 2.2.2.2 encapsulation mpls

interface vlan100

ip address 10.1.1.1 255.255.255.0

xconnect vfi 99

interface vlan200

ip address 10.2.2.1 255.255.255.0

xconnect vfi 98

This way you can segment traffic comming in on one port and forward to different destination.

Your configuration works well with QinQ H-VPLS however I am asking about MPLS H-VPLS

I still didnt try Matthew suggestion
