Abstract:
To enhance the reliability, bridged network is normally multi-homed
to an EVPN network, there are two categories of mechanisms to avoid
the layer 2 traffic loop. The first category does not require the PEs
participating in the control protocol of the bridged network, while
the second category requires that. [EVPN] described one of the first
category mechanisms called designated forwarder (DF) election to
achieve loop avoidance and vlan-based load balancing. This draft
mainly focuses on the second category of mechanisms which can achieve
intra-vlan MAC-based load balancing. MAC-based VLAN balancing is more
applicable than DF election mechanism if all end stations in bridged
network are on the same VLAN which can cause traffic congestion in DF
link.
