Phase 2 AARP Probe Time
This field allows the timeout for the AARP (Apple Address Resolution
Protocol) address claim probes made at router startup time to be lengthened
from the standard 2 seconds.
This may be necessary on AppleTalk networks which include WAN bridges.
On these networks, it may take longer than 2 seconds for a node on the far
side of a WAN bridge connection (logically still on the same AppleTalk
network) to respond to an AARP address claim made by the router.
