- Network > Virtual Routers > Static Routes
Optionally add one or more static routes. Click the
IPv6tab to specify the route using an Pv4 or IPv6 address. It is usually necessary to configure default routes (0.0.0.0/0) here. Default routes are applied for destinations that are otherwise not found in the virtual router’s routing table.
Static Route Settings
Enter a name to identify the static route (up to 31 characters). The name is case-sensitive and must be unique. Use only letters, numbers, spaces, hyphens, and underscores.
Select the interface to forward packets to the destination, or configure the next hop settings, or both.
Select one of the following:
Specify the administrative distance for the static route (10-240; default is 10).
Specify a valid metric for the static route (1 - 65535).
Select the route table into which the firewall installs the static route:
To enable Bidirectional Forwarding Detection (BFD) for a static route on a PA-3200 Series, PA-5200 Series, PA-7000 Series, or VM-Series firewall, select one of the following:
None (Disable BFD)to disable BFD for the static route.
To use BFD on a static route:
Select to enable path monitoring for the static route.
Select the condition under which the firewall considers the monitored path down and thus the static route down:
Allto avoid the possibility of a single monitored destination signaling a static route failure when that monitored destination is simply offline for maintenance, for example.
Preemptive Hold Time (min)
Enter the number of minutes a downed path monitor must remain in Up state—the path monitor evaluates all of its member monitored destinations and must remain Up before the firewall reinstalls the static route into the RIB. If the timer expires without the link going down or flapping, the link is deemed stable, path monitor can remain Up, and the firewall can add the static route back into the RIB.
If the link goes down or flaps during the hold time, path monitor fails and the timer restarts when the downed monitor returns to Up state. A
Preemptive Hold Timeof zero causes the firewall to reinstall the static route into the RIB immediately upon the path monitor coming up. Range is 0-1,440; default is 2.
Enter a name for the monitored destination (up to 31 characters).
Select to enable path monitoring of this specific destination for the static route; the firewall sends ICMP pings to this destination.
Select the IP address that the firewall will use as the source in the ICMP ping to the monitored destination:
Enter a robust, stable IP address or address object for which the firewall will monitor the path. The monitored destination and the static route destination must use the same address family (IPv4 or IPv6)
Ping Interval (sec)
Specify the ICMP ping interval in seconds to determine how frequently the firewall monitors the path (pings the monitored destination; range is 1-60; default is 3).
Specify the number of consecutive ICMP ping packets that do not return from the monitored destination before the firewall considers the link down. Based on the
Allfailure condition, if path monitoring is in failed state, the firewall removes the static route from the RIB (range is 3-10; default is 5).
For example, a Ping Interval of 3 seconds and Ping Count of 5 missed pings (the firewall receives no ping in the last 15 seconds) means path monitoring detects a link failure. If path monitoring is in failed state and the firewall receives a ping after 15 seconds, the link is deemed up; based on the
Allfailure condition, path monitoring to
Allmonitored destinations can be deemed up, and the Preemptive Hold Time starts.
