Configuring Static Routes For Fc; Configuration Restrictions And Guidelines; Configuration Procedure; Configuring Fspf - HP 5920 series Configuration Manual

After receiving an LSU, a switch needs to acknowledge its LSR with an LSA. Otherwise, the
neighboring switch retransmits the LSR.
How FSPF works
FSPF works as follows:
The switch periodically sends hello packets to establish neighbor relationships with other switches.
1.
After establishing neighbor relationships, the switches synchronize LSDBs by exchanging all LSRs
2.
in their respective LSDBs. A switch carries LSRs in LSUs and acknowledges received LSRs with
LSAs.
After the synchronization is complete, the LSDB in each switch contains LSRs of all switches in the
3.
fabric.
The switch uses the Dijkstra algorithm to calculate the shortest paths to other switches based on the
4.
local LSDB. Then, it determines the outgoing interfaces and generates an FSPF routing table.
When the network topology or link state changes, the switch floods a new LSR to its neighboring
5.
switches. After receiving the LSR, the neighboring switches add it to their LSDBs and flood it to their
respective neighbors. In this way, all switches in the fabric receive that LSR.
Local LSDB updating results in SPF calculation. The calculated shortest path tree list is updated to
6.
the FSPF routing table.

Configuring static routes for FC

Configuration restrictions and guidelines

The destination address of a static FC route is in the range of 010000 to EFFFFF (hexadecimal). You
•
cannot configure a route with a well-known address as the destination address.
The outgoing interface of a static FC route can only be a VFC interface.
•
• If you configure two routes with the same destination address, mask, and outgoing interface, but
with different costs, the route configured later applies.
The maximum number of static routes allowed in a VSAN is 256.
•

Configuration procedure

To configure a static FC route:
Step
1. Enter system view.
2. Enter VSAN view.
3. Configure a static FC
route.

Configuring FSPF

FSPF is enabled by default. Generally, you do not need to make special configurations.
You can change FSPF parameters on a per-VSAN or per-interface basis as needed.
