[j-nsp] srx ipsec tunnel over mpls l3vpn

[Emille Blanc]

Based on what you described, it sounds like you already got your MPLS/LDP running in a packet-mode routing-instance, as otherwise MPLS is dropped on an SRX in flow mode.

No obvious ideas with the output provided otherwise.
Do the flows in your IPSEC instance get created?

Anyone ever done it ?  To be clear, I have mpls/ldp/ospf/bgp enabled the SRX
such that I have an l3vpn functional into the SRX.

 

I have a lo0.99 interface as the external interface used for ike/ipsec.
Seems that I'm pretty close to getting this done, as i have ike phase 1 up
and ike phase 2 up, but only seeing encrypted packets as I try to ping
between the st0.0 interface and the ms-0/0/0.1 inside interface on the other
side (mx104 with ms-mic-16g)

 

Let me know what I'm missing.

 

I'm seeing drops in these to show outputs. which seems to coincide with a
100-packet ping test...
