Re: Juniper MX - Routed pseudowire using LDP - VPWS or VPLS
I do see one benefit to using the stitched LT VPWS solution - MAC learning. On the VPWS solution, your PE devices are not learning the MAC addresses. I also noticed that Juniper is a bit strange with VPLS attached to the IRB in that you never see the IRB MAC in the VPLS instance. But I think this has more to do with the behavior of IRB in general on Juniper as I don't see any of the IRB MAC addresses present in the table, even for IRBs not used on the VPLS circuit. It's entirely possible I'm using the wrong commands. :) -ben On Mon, Mar 19, 2018 at 4:27 PM, Ben Bartsch wrote: > The other solution is a stitched LT configuration.

Re: Juniper MX - Routed pseudowire using LDP - VPWS or VPLS
The other solution is a stitched LT configuration. One LT is the L3 endpoint, the other is the PW endpoint. You use VPWS with this one. I suppose you might be able to do VPLS instead if you wanted to. I am running eBGP on this circuit too. It's a bit more complicated for troubleshooting. I'm not sure what benefit this has over the IRB method.

Re: Juniper MX - Routed pseudowire using LDP - VPWS or VPLS
Absolutely! I'm running a eBGP session over this ATM. We are going to try to backhaul our customers through a Dell whitebox running IPI OcNOS configured with an 'LDP fabric' to a core MX. To use an IRB as a L3 endpoint you have to use VPLS on the MX (Junos version 15.1R6.7).

You can either attach the end of the l2circuit to an LT interface, or a PS interface. https://www.google.com/amp/s/tgregory.org/2016/07/10/pseudowire-headend-termination-pwht-for-juniper-mx/amp/ https://www.juniper.net/documentation/en_US/junos/topics/concept/pseudowire-subscriber-interfaces-overview.html https://www.juniper.net/documentation/en_US/junos/topics/usage-guidelines/services-configuring-logical-tunnel-interfaces.html On Sat, Mar 17, 2018, 9:27 AM Ben Bartsch wrote: > When we had Cisco ASR 920/903 and ASR9k, I could attach a layer 2 > pseudowire endpoint on that device to a layer 3 BDI/BVI.

Juniper MX - Routed pseudowire using LDP - VPWS or VPLS
When we had Cisco ASR 920/903 and ASR9k, I could attach a layer 2 pseudowire endpoint on that device to a layer 3 BDI/BVI. I'm trying to do the same thing on a Juniper MX 480/960 and it does not appear to be supported (for LDP at least - MP-BGP might be supported). We could do either VPWS or VPLS on the PE device handoff to the CE (layer 2 only). JTAC has somewhat confirmed this is not supported for LDP, but they only do break/fix, not new config. We do not have professional services (we are broke). Any Juniper routerheads out there that have seen this done using LDP without having to hairpin on the MX? Thanks, y'all. -ben
