BVI interface on ISR not passing through port-channel

[enkli]

Hello,

I have a ISR4K router connected through Portchannel to a Cisco 3850 switch.

Everything is ok so I have put an IP to port-channel on router side and it is pingable.

Meanwhile I have created som BVI interfaces working on different Vlans lets say 20, 30 and 50. The BVI have also IP addresses and I have enabled vlan on this. and created a DHCP pool on the router.

But if I put a port as access vlan 20  on the switch it does not get DHCP on Vlan 20

DHCP not passing so tagget packets do not pas the Portchannel.

Any idea or is it something that I am missing?

REgards,

Vlan and BVI and port channel!! Sorry I so confused here.

Can you share router config and topolgy

You need to provide more information here and configuration

if the Port-channel is Layer 3 then you need to have associated sub-interface for the respected VLAN to work as expected (as i understand your input from the post)

Thanks to all for the replies.
