No ping between VLANs

I finally setup GNS3 and play Cumulus(v3.7.1) in it. Tried a very basic setup and could not make ping between different vlan on the same bridge.

Here is my interface.conf:
code:
auto swp6
iface swp6

auto swp8
iface swp8

auto bridge
iface bridge
bridge-ports swp6 swp7 swp8
bridge-vids 16 18-20
bridge-vlan-aware yes

auto vlan16
iface vlan16
address 10.36.16.1/24
vlan-id 16
vlan-raw-device bridge

auto vlan18
iface vlan18
address 10.36.18.1/24
vlan-id 18
vlan-raw-device bridge



Now ping from 10.36.16.59 (connected to swp6) to 10.36.18.66 (connected to swp8) failed. The only traffic shows in wireshark is ARP (who is 10.36.16.1) and there is no answer for this ARP request.


On the VPC:
code:
VPCS> sh

NAME IP/MASK GATEWAY MAC LPORT RHOST:PORT
VPCS1 10.36.16.59/24 10.36.16.1 00:50:79:66:68:03 10084 127.0.0.1:10085
fe80::250:79ff:fe66:6803/64


code:
VPCS> sh

NAME IP/MASK GATEWAY MAC LPORT RHOST:PORT
VPCS1 10.36.18.66/24 10.36.18.1 00:50:79:66:68:05 10086 127.0.0.1:10087
fe80::250:79ff:fe66:6805/64



I must missed something here. Please help. Thanks.

I got it figured out. I forget to set the port as access port. 😉
