Figure 31 Zone merge process between two switches
The zone merge process is as follows:
1.
Switch A and Switch B are new neighbors to each other. Suppose that Switch A first initiates a
merge to Switch B:
a.
Switch A sends an MRRA request carrying the size of its data to be merged to Switch B.
b.
After receiving the MRRA request, Switch B determines whether to accept the merge according
to its local data size.
−
If the size of the data to be merged is acceptable, it replies with an ACC packet.
−
If the size of the data to be merged is not acceptable, it replies with an RJT packet.
c.
After receiving the ACC packet, Switch A sends an MR request containing its zone data to
Switch B.
d.
After receiving the MR request, Switch B obtains the zone data and merges it with its local zone
data. Then, it replies with an ACC packet for a successful merge or with an RJT packet
containing the cause of failure for a failed merge.
2.
After the merge process initiated by Switch A is complete:
{
If Switch B has the same local data as Switch A or has a subset of the local data of Switch A,
Switch B ends the merge process with Switch A.
{
Otherwise, Switch B initiates a merge process with Switch A.
The merge process is similar to that initiated by Switch A to Switch B as shown in steps 5, 6,
7, and 8 in
