  • 1.  Packet capture on a MPLS network

    Posted 07-19-2023 12:13

    Hi,

    I have a couple of SRX300 acting as PEs on which i would like to perform a packet capture. I especially want to capture packets related to a xconnect i created between a SRX300 and a Cisco ISR. On each access side of both PEs i have a host.

    I would like the packet capture to be performed on the mpls interface (towards the backbone) of one SRX300 so i can sample a couple of frames including some that brings a simple ping i am performing between the two hosts connected to each other thanks to the L2circuit.

    I tried a couple of scenario but none of them helped.

    Thanks in advance for your kind help.

    Regards,

    Jerems.

    Is this method supposed to help in capturing mpls packets ? I aim to capture traffic that contains L2VPN & L3VPN labeled packets like this :
