The domain 1 view of the fabric topology.
1.
Domain 1 is owner of the LSR (link state record).
2.
This is a 16-bit counter starting at 0x0000, incremented by one for each switch during flooding and
3.
by one for each second held in the database. This field is used as a tie-breaker if incarnation numbers
are the same.
This is a 32-bit value between 0x80000001 and 0x7FFFFFFF. which is incremented by one each
4.
time the originating switch transmits an LSR. This is used before LSR Age.
The path to domainID 237, switch 1.
5.
The path to domain ID 238, switch 5.

7.
The path to domain ID 239, switch 3.
8.
The path to domain ID 1, switch 2.
9.
Use the show fspf vsan vsan-id interface command to verify that the FSPF parameters are correct for
Step 2
each interface and verify that the interface is in the FSPF active state.
