Advanced PNNI Configuration
Displaying the Maximum Administrative Weight Percentage Configuration
To display the node ATM PNNI maximum AW percentage configuration, use the following privileged
EXEC command:
Command
show atm pnni local-node
Example
The following example shows the maximum AW percentage configuration using the show atm pnni
local-node privileged EXEC command:
Switch# show atm pnni local-node

Configuring the Precedence

The route selection algorithm chooses routes to particular destinations using the longest match reachable
address prefixes known to the switch. When there are multiple longest match reachable address prefixes
known to the switch, the route selection algorithm first attempts to find routes to reachable addresses
with types of greatest precedence. Among multiple longest match reachable address prefixes of the same
type, routes with the least total administrative weight are chosen first.
Local internal reachable addresses, whether learned via Integrated Local Management Interface (ILMI)
or as static routes, are given highest precedence or a precedence value of one. The precedence of other
reachable address types is configurable.
