Unable to ping from vlan interface

i am trying to configure the mwan3 package where secondary wan is a untagged vlan.

when i perform the mwan3 ping test on secondary wan (below command and result )

root@OpenWrt:~# ping -I eth1.10 -c 5
PING ( 56 data bytes

--- ping statistics ---
5 packets transmitted, 0 packets received, 100% packet loss

however , when i perform the ping without mentioning the interface , it works just fine.

root@OpenWrt:~# ping -c 5
PING ( 56 data bytes
64 bytes from seq=0 ttl=118 time=2.086 ms
64 bytes from seq=1 ttl=118 time=1.996 ms
64 bytes from seq=2 ttl=118 time=2.036 ms
64 bytes from seq=3 ttl=118 time=1.972 ms
64 bytes from seq=4 ttl=118 time=1.991 ms

--- ping statistics ---
5 packets transmitted, 5 packets received, 0% packet loss
round-trip min/avg/max = 1.972/2.016/2.086 ms

can someone tell me why am i unable to ping from untagged vlan.

Is that interface up and configured?
Does it have internet connectivity?
