Unable to ping from vlan interface

[Vijay_Raj]

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 8.8.8.8 -I eth1.10 -c 5
PING 8.8.8.8 (8.8.8.8): 56 data bytes

--- 8.8.8.8 ping statistics ---
5 packets transmitted, 0 packets received, 100% packet loss
root@OpenWrt:~# 

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

root@OpenWrt:~# ping 8.8.8.8 -c 5
PING 8.8.8.8 (8.8.8.8): 56 data bytes

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

[Vijay_Raj]

yes , it is up and has internet connectivity. Default route is set to the vlan interface as well .
