ZXR10 2900E Series Configuration Guide
l Switch A is the master node in ZESR domain 1 with port 1/1 as its primary port and
port 1/2 as its secondary port. Switch A is also the master node in ZESR domain 2
with port 1/2 as its primary port and port 1/1 as its secondary port.
l
Switches B to D are the transit nodes in both ZESR domains.
Note:
When multiple ZESR domains are configured on a physical ring, service data traffic in
different ZESR domains can be planned to go through different paths by proper settings
to achieve load balancing.
