The first part of this example specifies the IP address of the subinterface, the router protocol--the router uses IS-IS as
an IP routing protocol--and it creates the first bundle called new-york and enters bundle configuration mode:
interface atm 1/0.1 multipoint
ip address 10.0.0.1 255.255.255.0
ip router isis
From within bundle configuration mode, the next portion of the configuration uses two protocol commands to enable IP and Open
Systems Interconnect (OSI) traffic flows in the bundle. The OSI routing packets will use the highest precedence VC in the
bundle. The OSI data packets, if any, will use the lowest precedence VC in the bundle. If configured, other protocols, such
as IPX or AppleTalk, will always use the lowest precedence VC in the bundle.
As the indentation levels of the preceding and following commands suggest, subordinate to bundle new-york is a command that
configures its protocol and a command that applies the class called bundle-class to it.
protocol ip 22.214.171.124 broadcast
protocol clns 49.0000.0000.2222.00 broadcast
The class called bundle-class, which is applied to the bundle new-york, includes a protocol ip inarp command. According to inheritance rules, protocol ip , configured at the bundle level, takes precedence over protocol ip inarp specified in the class bundle-class.
The next set of commands beginning with pvc-bundle ny-control 207 , which are further subordinate, add four VCs (called ny-control, ny-premium, ny-priority, and ny-basic) to the bundle new-york.
A particular class--that is, one of the classes predefined in this configuration example--is applied to each VC to configure
it with parameters specified by commands included in the class.
As is the case for this configuration, to configure individual VCs belonging to a bundle, the router must be in bundle mode
for the mother bundle. For each VC belonging to the bundle, the subordinate mode is pvc-mode for the specific VC.
The following commands configure the individual VCs for the bundle new-york:
pvc-bundle ny-control 207
pvc-bundle ny-premium 206
pvc-bundle ny-priority 204
pvc-bundle ny-basic 201
