Configuring WAN Reroute
WAN reroute lets you set up an alternate route so that if a primary link fails, the
router automatically initiates a new connection to the destination through the
alternate route.
You can use any type of link as the alternate link and any type of link as the
primary link. The alternate link does not need to be connected to the same end
point as the primary link.
If HPR is used on the primary link and alternate link, when the primary link fails,
HPR’s Non-disruptive Path Switch function will automatically reroute traffic to the
alternate link without disrupting end user sessions.
In this configuration example, the router performing the WAN reroute function is
configured with two APPN link station definitions; one link station is defined over the
primary interface and the other is over the alternate interface. The destination router
needs to have APPN enabled on the port. If the destination router has a link station
defined, that link station should not try to bring up the connection in order to avoid
extra traffic.
In this example, frame relay is the primary route from NN22 to NN6.
