Hi Xyxue,
The lookup was performed in FIB index 1– you must have used ‘set int ip table
host-XXX YYY’ - but the route you added is in the default table.
If you want the routes in the same table as the interface do;
Ip route add table YYY 192.168.3.0/24 via mpls-tunnel0 out-label 1023
Regards,
Neale
p.s. are you really constructing the L3VPN from a [full] mesh of MPLS tunnels,
or is it LDP in the core?

Subject: [vpp-dev] MPLS L3VPN PING FAILED
Hi guys,
I have the following configuration:
mpls tunnel add via 2.1.1.1 host-eth1 out-label 1024
set int state mpls-tunnel0 up
ip route add 192.168.3.0/24 via mpls-tunnel0 out-label 1023
Ping from CE to PE ,and the PE drop it.
That is the fib :
192.168.3.0/24
