Verifying That MVRP Is Updating VLAN Membership on Distribution Switch C
Verify that MVRP is updating VLAN membership on distribution Switch C by displaying
the Ethernet switching interfaces and associated VLANs on distribution Switch C.
List the Ethernet switching interfaces on the switch:
user@Distribution-Switch-C> show ethernet-switching interfaces
Interface State VLAN members
xe-0/1/1.0 up __mvrp_100__
__mvrp_200__
__mvrp_300__
xe-0/1/0.0 up __mvrp_100__
__mvrp_200__
List the VLANs that were created dynamically using MVRP on the switch:
user@Distribution-Switch-C> show mvrp dynamic-vlan-memberships
MVRP dynamic vlans for routing instance 'default-switch'
(s) static vlan, (f) fixed registration
VLAN ID Interfaces
100 xe-0/1/1.0
xe-0/1/0.0
200 xe-0/1/1.0
xe-0/1/0.0
300 xe-0/1/1.0
Note that this scenario doesn't have any fixed registration, which is typical when MVRP
is enabled.
Distribution Switch C has two trunk interfaces. Interface
Switch C to Access Switch A and is therefore updated to show that it is a member of all
the VLANs that are active on Switch A. Any traffic for those VLANs will be passed on
from distribution Switch C to Switch A, through interface
connects distribution Switch C to Switch B and is updated to show that it is a member
of the two VLANs that are active on Switch B. Thus, distribution Switch C sends traffic
for and to both Switch A and Switch B. But distribution Switch C sends traffic
finance lab
for only to Switch A.

Distribution Switch C also has three dynamic VLANs created using MVRP:
