Globally configuring IS-IS on a device
The point-to-point option enables hello PDU padding on Point-to-Point interfaces.
To disable hello padding on an interface, refer to “Disabling and enabling hello padding on an
interface” on page 287.
Logging adjacency changes
The Brocade device can be configured to log changes in the status of an adjacency with another IS.
Logging of the adjacency changes is disabled by default. To enable or disable them, use either of
the following methods.
To enable logging of adjacency changes, enter the following command.
Brocade(config-isis-router)# log adjacency
Syntax: [no] log adjacency
To disable logging of adjacency changes, enter the following command.
Brocade(config-isis-router)# no log adjacency
Logging invalid LSP packets received
The Brocade device can be configured to provide logging of invalid LSP packets. Logging of the
invalid LSP packets is disabled by default. To enable or disable this function, use either of the
following methods.
To enable logging of invalid LSP packets, enter the following command.
Brocade(config-isis-router)# log invalid-lsp-packets
Syntax: [no] log invalid-lsp-packets
To disable logging of invalid LSP packets, enter the following command.
Brocade(config-isis-router)# no log invalid-lsp-packets
Disabling partial SPF optimizations
IS-IS employs certain partial SPF optimizations to make partial changes to the routing table in
network change situations where the topology of the network has not changed but where there
may be changes in the IP networks advertised by routers. These optimizations are termed partial
SPF optimizations.
You can optionally configure IS-IS to perform a full SPF calculation when any network (non-topology)
change occurs by using the disable-partial-spf-opt command. When disable-partial-spf-opt is
configured, IS-IS always runs full SPF for all such network changes.
To disable partial SPF calculations for IS-IS, enter the following command.
Brocade(config-isis-router)# disable-partial-spf-opt
Syntax: [no] disable-partial-spf-opt
To restore partial SPF optimizations, use the no form of this command.
