Configuring The Group Mac Address For Isis-Spb; Configuring Isis-Spb Authentication - HP 5920 series Configuration Manual

Step
3. Enable ISIS-SPB
adjacency change
logging.

Configuring the group MAC address for ISIS-SPB

ISIS-SPB uses a group MAC address for ISIS-SPB peer-to-peer communication. This group MAC specifies
the destination MAC address for ISIS-SPB protocol frames. Vendors might use different group MAC
addresses. You can change the ISIS-SPB control MAC for interoperability in a multivendor network.
To configure the group MAC address for ISIS-SPB:
Step
1. Enter system view.
2. Enter SPBM view.
3. Configure the group MAC
for ISIS-SPB.

Configuring ISIS-SPB authentication

ISIS-SPB authentication helps improve security in a SPBM network. It includes adjacency authentication
and area authentication.
Configuring ISIS-SPB adjacency authentication
ISIS-SPB adjacency authentication guarantees that SPBM nodes establish adjacencies only with
trustworthy neighbors.
SPBM nodes send adjacency authentication information (including the authentication method and
password) in ISIS-SPB hello packets. The recipient establishes or maintains an adjacency with the sender
only if the received authentication settings match its local authentication settings.
For two devices to establish an adjacency, you must configure the same authentication method and
password on them.
To prevent loss of adjacencies, use the following procedure when you modify adjacency authentication
settings:
1. Disable adjacency authentication for incoming ISIS-SPB hello packets on the neighbor devices.
2. Modify the authentication settings on the local end.
3. Modify the authentication settings on the remote end.
Enable adjacency authentication for incoming ISIS-SPB hello packets on the neighbor devices.

to the configuration terminal.
To display adjacency change messages on the
terminal screen, make sure the terminal logging
and terminal monitor commands are
configured.
