Juniper – SRv6 EVPN VPWS

nick Leave a comment

Yes it’s another EVPN VPWS lab but this time it’s with SRv6 so no MPLS involved. A couple of vjunos-router devices are running SRv6 and as usual, 2 Cisco devices are CEs.

Juniper – LDP Layer 2 Circuit

nick Leave a comment

This is a slight variation on a standard LDP Layer 2 circuit. Segment Routing is used for the transport labels and LDP is only running on the loopbacks of both PEs. vJunos-router is used for the lab.

Juniper – OSPF Unnumbered Ethernet Interfaces

nick Leave a comment

We have already done a lab with IS-IS and Unnumbered Interfaces so with this lab we will do the same but with OSPF instead of IS-IS.

The lab is EVPN E-Tree on Junos Evolved. New York is the Head Office (root) and the other sites are satellites (leaves).
