Hello! I've been doing some reading recently on Segment Routing. By all accounts, it seems that the (only?) implementation for SR supports L3VPN. Am I dumb and just missing the L2VPN bits, or is L3VPN simply the extent of the first generation? Sent from my iPhone
No, it works with L2VPNs also. Outer label is going to be SR label and inner label is your L2VPN label. Cheers, -Mohan On Sun, Sep 20, 2015 at 3:23 PM, Jason Lixfeld <jason@lixfeld.ca> wrote:

Hi, In most well designed IP routing stacks the way to get to a labeled (tunneled) next hop is decoupled from a service, so if a service requires such next hop it is upto (usually RIB) to return one (best, multiple might exist) which would be used for forwarding. If it is a Segment Routed one so it will then be used.
