You can also enable the logging of messages generated when a BGP neighbor resets, comes up, or goes
down by using the bgp log-neighbor changes router configuration command.

Configuring ISO CLNS Routing
The International Organization for Standardization (ISO) Connectionless Network Service (CLNS)
protocol is a standard for the network layer of the Open System Interconnection (OSI) model. Addresses
in the ISO network architecture are referred to as network service access point (NSAP) addresses and
network entity titles (NETs). Each node in an OSI network has one or more NETs. In addition, each node
has many NSAP addresses.

When you enable connectionless routing on the switch by using the clns routing global configuration
command, the switch makes only forwarding decisions, with no routing-related functionality. For
dynamic routing, you must also enable a routing protocol. The switch supports the Intermediate
System-to-Intermediate System (IS-IS) dynamic routing protocol that is based on the OSI routing
protocol for ISO CLNS networks.

When dynamically routing, you use IS-IS. This routing protocol supports the concept of areas. Within
an area, all routers know how to reach all the system IDs. Between areas, routers know how to reach the
proper area. IS-IS supports two levels of routing: station routing (within an area) and area routing
(between areas).
