Before this patch, each SRv6 behavior specifies a set of required
attributes that must be provided by the userspace application when such
behavior is going to be instantiated. If at least one of the required
attributes is not provided, the creation of the behavior fails.

This patchset provides support for the SRv6 End.DT4 and End.DT6 (VRF mode)
behaviors.
The SRv6 End.DT4 behavior is used to implement multi-tenant IPv4 L3 VPNs. It
decapsulates the received packets and performs IPv4 routing lookup in the
routing table of the tenant. The SRv6 End.DT4 Linux implement
Before this patch, a sniffer attached to a VRF used as the receiving
interface of L3 tunneled packets detects them as malformed packets and
it complains about that (i.e.: tcpdump shows bogus packets).
The reason is that a tunneled L3 packet does not carry any L2
information and when the VRF is set
SRv6 End.DT6 is defined in the SRv6 Network Programming [1].
The Linux kernel already offers an implementation of the SRv6
End.DT6 behavior which permits IPv6 L3 VPNs over SRv6 networks. This
implementation is not particularly suitable in contexts where we need to
deploy IPv6 L3 VPNs among differe
We introduce two callbacks used for customizing the creation/destruction of

Depending on the attribute (i.e.: SEG6_LOCAL_SRH, SEG6_LOCAL_TABLE, etc),

We introduce the "vrftable" attribute for supporting the SRv6 End.DT4 and
End.DT6 behaviors in iproute2.
The "vrftable" attribute indicates the routing table associated with
the VRF device used by SRv6 End.DT4/DT6 for routing IPv4/IPv6 packets.
The SRv6 End.DT4/DT6 is used to implement IPv4/IPv6 L

Connect hosts H1 and H2 using two intermediate encapsulation routers
(LER1 and LER2). These routers encapsulate traffic from the hosts,
including the original Ethernet header, into MPLS.
Use ping to test reachability between H1 and H2.
