1. Provides the Domain 1 view of the fabric topology.
2. Indicates that Domain 1 is owner of the LSR (Link State Record).
3. This is a 16-bit counter starting at 0x0000, incremented by one for each switch during flooding and
by one for each second held in 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 first before LSR Age.
Indicates the path to Domain 237, Switch switch1.
5.
6. Indicates the path to Domain 238, Switch switch5.
7. Indicates that switch1, Domain ID 237 is the owner.
8. Indicates the path to Domain 239, Switch switch3.
Indicates the path to Domain 1, Switch switch2
9.
Step 2 Verify that the FSPF parameters are correct for each interface by entering the following command at the
exec prompt:
switch1# show fspf vsan 1 interface fc1/2
