Verifying That MVRP Is Updating VLAN Membership on Distribution Switch C
Purpose Verify that MVRP is updating VLAN membership on distribution Switch C by displaying
the Ethernet switching interfaces and associated VLANs on distribution Switch C.
Action List the Ethernet switching interfaces on the switch:
user@Distribution-Switch-C> show ethernet-switching interfaces
Interface State VLAN members Blocking
xe-0/1/1.0 up __mvrp_100__ unblocked
__mvrp_200__ unblocked
__mvrp_300__ unblocked
xe-0/1/0.0 up __mvrp_100__ unblocked
__mvrp_200__ unblocked
List the VLANs that were created dynamically using MVRP on the switch:
user@Distribution-Switch-C>
show mvrp dynamic-vlan-memberships
VLAN Name Interfaces
------------------- ----------------
__mvrp_100__ xe-0/1/1.0
xe-0/1/0.0
__mvrp_200__ xe-0/1/1.0
xe-0/1/0.0
__mvrp_300__ xe-0/1/1.0
Meaning Distribution Switch C has two trunk interfaces. Interface xe-0/1/1.0 connects distribution
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
xe-0/1/1.0
. Interface
xe-0/1/0.0
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
finance
and
lab
to both Switch A and Switch B. But distribution Switch C sends traffic
for
sales
only to Switch A.
Distribution Switch C also has three dynamic VLANs created using MVRP:
mvrp_100
,
mvrp_200 , and mvrp_300 . The dynamically created VLANs mvrp_100 and mvrp_200 are
active on interfaces xe-0/1/1.0 and xe-0/1/1.0 , and dynamically created VLAN mvrp_300
is active on interface xe-0/1/1.0 .

Example: Configuring Layer 2 Protocol Tunneling on EX Series Switches
Layer 2 protocol tunneling (L2PT) allows you to send Layer 2 protocol data units (PDUs)
across a service provider network and deliver them to EX Series switches that are not
part of the local broadcast domain. This feature is useful when you want to run Layer 2
