Article ID: KB15172 KB Last Updated: 18 Apr 2020Version: 3.0
Summary:

Assuming you have STP running, this article will explain how to configure GVRP on EX Series Switches.

Note: Junos OS Release 10.x and greater supports Dynamic VLAN assignment; earlier releases support VLAN Pruning.

Solution:

To configure GVRP on EX Series switches, enter into the "Protocols" Stanza. Under that Stanza you can configure GVRP Globally for all trunk connections or you can specifically specify which trunk interfaces will apply the GVRP protocol.

NOTE:   VLAN Pruning is supported prior to the 10.x release. Dynamic VLAN will be supported starting with the 10.x release. 
NOTE:   GVRP cannot be enabled on access interfaces.


Before Configuring GVRP:

{master:0}[edit protocols]
root@EX# show
igmp-snooping {
     vlan all;
}
lldp {
     interface all;
}
lldp-med {
     interface all;
}
rstp;



After configuring GVRP (Globally):

{master:0}[edit protocols]
root@EX# show
igmp-snooping {
     vlan all;
}
lldp {
    interface all;
}
lldp-med {
     interface all;
}
gvrp;
rstp;



After Configuring GVRP with specific interfaces:

{master:0}[edit protocols]
root@EX# show
igmp-snooping {
     vlan all;
}
lldp {
     interface all;
}
lldp-med {
     interface all;
}
gvrp {
     interface ge-0/0/0.0;
}

rstp;
Modification History:
2020-04-18: Added supported product and versions as the feature isn't widely used on all switching products.
