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.

Subject: [vpp-dev] sr mpls fault
Hi guys,
Is the vpp support sr mpls now?
After I configured the following command, I configured 'sr mpls steer l3
3.1.1.0/24 via sr policy bsid 33 del'.
Then there was a SIGABRT . Are there any illegal command in my configuration?
configuration：
create host-interface name eth2 mac 00:0c:29:6d:b0:82
create host-interface name eth1 mac 00:0c:29:6d:b0:78
create host-interface name eth3 mac 00:0c:29:6d:b0:8c
