The m-VPLS passes the L2CP frames to the ISAM control plane for protocol
processing (typically RSTP/MSTP).
As a general rule, the v-VPLS processes frames as follows.
After being subjected to self-learning,
•
•
•
•
Multicast frames with unknown Multicast IP address are:
•
•
Frames where the destination MAC address is the ISAM system MAC address are
eligible for VPRN processing (if applicable).
Frames with Broadcast MAC destination address are flooded to all SAPs
Note that frame forwarding may be subjected to some operator control (e.g. traffic
filtering, user-to-user communication permit/deny).
Also, self-learning is subjected to security restrictions; in particular, a MAC address
learned on the network side may not be relearned on the user side to avoid network
address hijacking.

L2CP and LACP destination MAC address definitions
Frame type
L2CP pause frames (1)
L2CP frames
LACP frames (2)
The Ether type and op-code can be anything.
LACP frames are L2CP frames with the indicated destination MAC address.
special protocol frames (DHCP, ARP, OSPF, RIP, IS-IS, IGMP,...) are processed
according to corresponding protocol rules
frames with a known Unicast MAC destination address are unicast forwarded to
the proper egress SAP
frames with unknown Unicast MAC destination address are flooded to all v-VPLS
SAPs
multicast frames with known Multicast IP destination address are forwarded to the
corresponding SAP list
discarded if IGMP snooping is enabled on the v-VPLS
flooded to all SAPs if IGMP snooping is disabled on the v-VPLS
