MPLS L3 VPN Label

[shashakil (shakil s)]

Hi MPLS team,
I understood MPLS L3 VPN concept along with your brief example.
However, I have one doubt based on your example “MPLS Layer 3 VPN Configuration” in which MPLS VPN label has been advertised by PE1 and PE2. This VPN label is having number for PE1 and PE2 or advertised different number…? you explained PE1 side but PE2 side through cli was not mentioned.

PE1 side only shown snap shot

Please explain me with snap shot.

Regards
Shakil

Hello Shakil

Take a look at this response:

MPLS Layer 3 VPN Configuration

Hello Shakil In an MPLS L3 VPN, the VPN label is not the same for PE1 and PE2. Each PE router generates its own VPN labels for the VPN routes it advertises to its peers. However, when these labels traverse the MPLS network, they remain the same throughout the journey of the packet. When the packet arrives at PE2, you will see that it will have the same VPNv4 label. This can be seen in the lesson, if you take a look at the output from the show mpls forwarding-table command on PE2, you will se…

I hope this has been helpful!
