Seems there is a regression of SRv6 End.DT6 function in VRF mode. In the following scenario packet is decapsulated successfully on vrf10 interface but not forwarded to vrf10's slave interface: ip netns exec r4 ip -6 nexthop add id 1004 encap seg6local action End.DT6 vrftable 10 dev vrf10 ip netns exec r4 ip -6 route add fcff:0:4:200:: nhid 1004 In End.DT6 legacy mode everything works good: ip netns exec r4 ip -6 nexthop add id 1004 encap seg6local action End.DT6 table 10 dev vrf10 ip netns exec r4 ip -6 route add fcff:0:4:200:: nhid 1004 The issue impacts even stable v5.18.1. Please help to fix it. Thanks! Anton
