    Routing Tab

    The following table describes the virtual router’s runtime stats for the Route Table, Forwarding Table, and the Static Route Monitoring table.
    Runtime Stat
    Description
    Route Table
    Route Table
    Select Unicast or Multicast to display either the unicast or multicast route table.
    Display Address Family
    Select IPv4 Only, IPv6 Only, or IPv4 and IPv6 (default) to control which group of addresses to display in the table.
    Destination
    IPv4 address and netmask or IPv6 address and prefix length of networks the virtual router can reach.
    Next Hop
    IP address of the device at the next hop toward the Destination network. A next hop of 0.0.0.0 indicates the default route.
    Metric
    Metric for the route. When a routing protocol has more than one route to the same destination network, it prefers the route with the lowest metric value. Each routing protocol uses a different type of metric; for example, RIP uses hop count.
    Weight
    Weight for the route. For example, when BGP has more than one route to the same destination, it will prefer the route with the highest weight.
    Flags
    • A?B—Active and learned via BGP
    • A C—Active and a result of an internal interface (connected) - Destination = network
    • A H—Active and a result of an internal interface (connected) - Destination = Host only
    • A R—Active and learned via RIP
    • A S—Active and static
    • S—Inactive (because this route has a higher metric) and static
    • O1—OSPF external type-1
    • O2—OSPF external type-2
    • Oi—OSPF intra-area
    • Oo—OSPF inter-area
    Age
    Age of the route entry in the routing table. Static routes have no age.
    Interface
    Egress interface of the virtual router that will be used to reach the next hop.

    Forwarding Table
    The firewall chooses the best route—from the route table (RIB) toward a destination network—to place in the FIB.
    Display Address Family
    Select IPv4 Only, IPv6 Only, or IPv4 and IPv6 (default) to control which route table to display.
    Destination
    Best IPv4 address and netmask or IPv6 address and prefix length to a network the virtual router can reach, selected from the Route Table.
    Next Hop
    IP address of the device at the next hop toward the Destination network. A next hop of 0.0.0.0 indicates the default route.
    Flags
    • u—Route is up.
    • h—Route is to a host.
    • g—Route is to a gateway.
    • e—Firewall selected this route using Equal Cost Multipath (ECMP).
    • *—Route is the preferred path to a destination network.
    Interface
    Egress interface the virtual router will use to reach the next hop.
    MTU
    Maximum transmission unit (MTU); maximum number of bytes that the firewall will transmit in a single TCP packet to this destination.
    Refresh
    Click to refresh the runtime stats in the table.
    Static Route Monitoring
    Destination
    IPv4 address and netmask or IPv6 address and prefix length of a network the virtual router can reach.
    Next Hop
    IP address of the device at the next hop toward the Destination network. A next hop of 0.0.0.0 indicates the default route.
    Metric
    Metric for the route. When there is more than one static route to the same destination network, the firewall prefers the route with the lowest metric value.
    Weight
    Weight for the route.
    Flags
    • A?B—Active and learned via BGP
    • A C—Active and a result of an internal interface (connected) - Destination = network
    • A H—Active and a result of an internal interface (connected) - Destination = Host only
    • A R—Active and learned via RIP
    • A S—Active and static
    • S—Inactive (because this route has a higher metric) and static
    • O1—OSPF external type-1
    • O2—OSPF external type-2
    • Oi—OSPF intra-area
    • Oo—OSPF inter-area
    Interface
    Egress interface of the virtual router that will be used to reach the next hop.
    Path Monitoring (Fail On)
    If path monitoring is enabled for this static route, Fail On indicates:
    • All—Firewall considers the static route down and will fail over if all of the monitored destinations for the static route are down.
    • Any—Firewall considers the static route down and will fail over if any one of the monitored destinations for the static route is down.
    If static route path monitoring is disabled, Fail On indicates Disabled.
    Status
    Status of the static route based on ICMP pings to the monitored destinations: Up, Down, or path monitoring for the static route is Disabled.
