Configuring Link Selection
Link selection applies to parallel PNNI links between two switches. Link selection allows you to choose
the method the switch uses during call setup for selecting one link among multiple parallel links to
forward the call.
Note Calls always use the load balance method over parallel IISP links between two switches.
Table 11-2 lists the PNNI link selection methods from which you can choose.

2 blocking-minimize Places the call on the link so that
higher bandwidth is available for
subsequent calls, thus minimizing
call blocking. CBR, VBR-RT,
VBR-NRT
3 transmit-speed-maximize Places the call on the highest speed
link.

4 load-balance Places the call on the link so that the
load is balanced among parallel links
for a group.
