IEEE 802.1ak-2007 MVRP (MX Series routers)
—The Multiple VLAN Registration
Protocol (MVRP) is a standards-based Layer 2 network protocol used among
switches to dynamically share and update VLAN information with other bridges.
VLAN information exchanged includes:
■
The set of VLANs that currently have active members
■
The ports through which the active members can be reached
To operate MVRP, edge ports should have the static VLAN configuration. The
edge ports will not be configured for MVRP. MVRP is only enabled on the
core-facing trunk ports where no static VLANs are configured.
To configure MVRP, include the
mvrp
statement and desired options at the

hierarchy level.

Elevated packet drops during oversubscription (MX Series routers with Trio
MPC/MIC interfaces)
—During periods of oversubscription, the WRED process
drops more packets than expected from relatively full queues. There is no
configuration for this feature, which transparently applies scaling to
oversubscribed queues.
