First, create a bridge on both devices and add needed interfaces as bridge ports. To change untagged VLAN for a bridge port, use the pvid setting. The Bridge1 will be acting as an IGMP querier. Below are configuration commands for the Bridge1:
| Code Block | ||
|---|---|---|
| ||
/interface bridge add igmp-snooping=yes multicast-querier=yes name=bridge1 /interface bridge port add bridge=bridge1 interface=ether2 pvid=10 add bridge=bridge1 interface=ether3 pvid=10 add bridge=bridge1 interface=ether4 pvid=10 add bridge=bridge1 interface=ether5 pvid=20 add bridge=bridge1 interface=sfp-sfpplus1 pvid=10 |
And for the Bridge2:
| Code Block | ||
|---|---|---|
| ||
/interface bridge add igmp-snooping=yes name=bridge1 /interface bridge port add bridge=bridge1 interface=ether3 pvid=10 add bridge=bridge1 interface=ether4 pvid=10 add bridge=bridge1 interface=ether5 pvid=20 add bridge=bridge1 interface=sfp-sfpplus1 pvid=10 |
| Note |
|---|
Bridge IGMP querier implementation can only send untagged IGMP queries. In case tagged IGMP queries should be sent or IGMP queries should be generated in multiple VLANs, it is possible to install a multicast package, add a VLAN interface and configure a PIM interface on VLAN. The PIM interface can be used as an IGMP querier. |
Make sure Then configure VLAN-related settings. Make sure to configure management access for devices. It is essential when configuring a bridge with VLAN filtering. In this example, a VLAN 99 interface with an IP address is added to the bridge. This VLAN will be allowed on the tagged sfp-sfpplus1 port. Below are configuration commands for the Bridge1:
...
| Code Block | ||
|---|---|---|
| ||
/interface vlan
add interface=bridge1 name=MGMT vlan-id=99
/ip address
add address=192.168.99.2/24 interface=MGMT network=192.168.99.0
/interface bridge vlan
add bridge=bridge1 tagged=bridge1,sfp-sfpplus1 vlan-ids=99 |
To change untagged VLAN for a bridge port, use pvid setting. Below are configuration commands for the Bridge1:
| Code Block | ||
|---|---|---|
| ||
/interface bridge port
set [find interface=ether2] pvid=10
set [find interface=ether3] pvid=10
set [find interface=ether4] pvid=10
set [find interface=ether5] pvid=20
set [find interface=sfp-sfpplus1] pvid=10 |
And for the Bridge2:
| Code Block | ||
|---|---|---|
| ||
/interface bridge port
set [find interface=ether3] pvid=10
set [find interface=ether4] pvid=10
set [find interface=ether5] pvid=20
set [find interface=sfp-sfpplus1] pvid=10 |

/interface bridge vlan
add bridge=bridge1 tagged=bridge1,sfp-sfpplus1 vlan-ids=99 |
Add bridge VLAN entries and specify tagged and untagged ports. The VLAN 99 entry was already created when configuring management access, only VLAN 10 and VLAN 20 should be added now. Below are configuration commands for the Bridge1:
...
At this point, VLANs and IGMP snooping are configured and devices should be able to communicate through the ports. However, it is recommended to go even a step further and apply some additional filtering options. Enable port ingress-filtering and frame-types on bridge ports. Below are configuration commands for the Bridge1:
