Re: [vpp-dev] sr mpls fault
Hi Xyxue, I’ll look into the crash. In the meantime, perhaps your config is somewhat curious. What is your intention with 3.1.1.0/24? It has been added as an extranet route (i.e. it’s in table 0 and table 1) but in table 0 you have an override of the route via the SR steering. If you remove the ip route for 3.1.1.0/24 in table 0, I expect there will be no crash. The SR policy says ‘forward in the same way as for label 1000’ but there is no local-label/route for 1000. You don’t need MPLS table 1. /neale From: <vpp-dev-boun...@lists.fd.io> on behalf of 薛欣颖 <xy...@fiberhome.com> Date: Monday, 27 November 2017 at 06:55 To: vpp-dev <vpp-dev@lists.fd.io> Subject: [vpp-dev] sr mpls fault Hi guys, Is the vpp support sr mpls now?
