Like 802.1AS, Multiple Registration Protocol (MRP) is an audio video bridging (AVB) feature
that is available on some FASTPATH platforms. MVR is a base registration protocol that
enables devices running an MRP application to register attributes to other devices in a
network. MRP provides an application to register attributes such as bandwidth for a given AV
stream and MAC address information. It is used by various applications to propagate the
registration. Blade switches support the following MRP applications:
• Multiple MAC Registration Protocol (MMRP). MMRP allows for the propagation MAC
address information in the network, and allows for the registration and deregistration of
both individual MAC address information and group MAC address membership. End
stations can request to join or leave a multicast group, or to register an individual MAC
address with a specific VLAN. MAC address entries can be dynamically registered and
deregistered if MMRP is administratively enabled on the switch.
• Multiple VLAN Registration Protocol (MVRP). MVRP registers VLANs in the network,
enabling automatic VLAN configuration on the switch. In a typical network, VLAN tagging
is common. Many nodes require ingress traf
fic to be tagged with a specific VLAN ID, and
other nodes require egress traffic to be transmitted with a specific VLAN ID. With the use
of MVRP on both ingress and egress, no manual VLAN configuration is required to pass
tagged traffic through the network.
Note: MRP framework must be available and enabled in all intermediate
devices to ensure that the propagation of the attributes occurs
throughout the network.
With MRP, network attributes are declared, registered, withdrawn, and removed
completely dynamically without any user intervention.
This dynamic nature is especially
useful in networks where the following is true:
- Network attributes are likely to change frequently
, requiring reconfiguration of the
intermediate devices.
- Recipients of these attributes frequently increase or decrease in number
.
- Each of these changes without a dynamic self-adjusting framework would require
constant attention from the network administrator
.
