This attribute specifies the type of High Performance Routing
(HPR) that is to be used on this node. The options are: none - the
node does not support HPR, anrOnly - the node only supports
Automatic Network Routing (ANR), or rtp - the node supports
Rapid Transport Protocol as an end point.
The default value of rtp ensures that the node can Aping other nodes
via a HPR pipe, this option is also required to allow dependent LU
sessions teminating on this node to use HPR and for the node to act
as a boundary node between ISR only nodes and the HPR capable
portion of the network. With this option, the node can work with
non-HPR capable nodes.
