Hi,
As shown in thread number #21611 also I trying to implement an SRv6 network
through VPP 22.06 I encounter the problem that after a certain number of
nodes (SID List >= 6) the Ingress router no longer forwards packets from
the interface and after a while VPP crashes

In my topology the situation is as follows:
SID LIST -> [Transit3 -> Ingress -> Transit2 -> Ingress -> Egress]
It works
SID LIST -> [Transit3 -> Ingress -> Transit2 -> Ingress -> Transit3 ->
Egress]
Does not work
[image: Topologia _EVE_NG.drawio.png]
Outgoing packets from the Ingress node to the Transit node become Ethernet
II packets.
This is the error output following the crash.
