Please be more specific about what ‘doesn’t work’. You script on n1 does:
#add gre tunnel create gre tunnel src 200.1.2.1 dst 200.1.2.2 set interface state gre0 up set interface ip address gre0 10.10.10.11/32 ip route add 2.1.1.0/24 via gre0 #del gre tunnel set interface state gre0 down create gre tunnel src 200.1.2.1 dst 200.1.2.2 del ip route del 2.1.1.0/24 via 200.1.2.2. that last route delete was not the route you added, so it won’t remove anything. What you need is ip route del 2.1.1.0/24 via gre0 and of course you need to do that before you delete the tunnel. /neale From: <vpp-dev@lists.fd.io> on behalf of "abbas ali chezgi via Lists.Fd.Io" <chezgi=yahoo....@lists.fd.io> Reply to: "che...@yahoo.com" <che...@yahoo.com> Date: Monday 17 February 2020 at 05:43 To: Vpp-dev <vpp-dev@lists.fd.io> Cc: "vpp-dev@lists.fd.io" <vpp-dev@lists.fd.io> Subject: [vpp-dev] sub interface after virtual interfaces doesn't work 1- create gre tunnel between n1--n2 2- add ip and route . it works 3- delete ip and route from gre and delete gre tunnel 4- create sub interface 5- add ip and route. it doesn't work [VPP-1841] sub interface after gre doesn't work - FD.io Jira<https://jira.fd.io/browse/VPP-1841> [VPP-1841] sub interface after gre doesn't work - FD.io Jira where can i look for it thanks.
