    The Routing tab provides Border Gateway Protocol (BGP) peering status for an ION device at a branch site or a data center.

    • Prisma SD-WAN

    The Routing tab provides Border Gateway Protocol (BGP) peering status for an ION device at a branch site or a data center. It includes information on BGP peer types, including classic, core, and edge peers depending on the type of site, namely a branch or a data center.
    In addition, it displays information on the BGP peering state and advertised and reachable prefixes. While the classic and core peers display advertised and reachable prefixes, the edge peer will display only reachable prefixes. Reachable prefixes are prefixes that the ION device learns from the peer, whereas advertised prefixes are prefixes that the ION device advertises to the classic and core peers.
    You may filter individual routes or prefixes from received and advertised prefixes along with network, Autonomous System (AS) path, and next-hop information. From advertised, reachable, or discoverable prefixes, you can search for specific routes or prefixes.
    Use routing to troubleshoot BGP connections and check if routes are learned from or advertised to the BGP peers. For example, you can verify whether a peer is connected by checking the peer's BGP state. If the peer is not connected, the State field will provide information on the peer's status, dropped connections, duration of BGP peer uptime and downtime, and notifications. If any prefix id is not reachable, check if the route is learned from the WAN edge or is advertised to the core or classic peer.
    To view the routing statistics, navigate to Monitor ActivityRouting, select a site by searching its Name, Address, Admin State or, Site Type. When done, the selected site routing information is displayed.
    BGP
    The routing information for the selected site displays the following:
    • Device—ION device name. Click to view the routing configuration of the device.
    • Peer IP—IP address of the BGP peer (WAN edge router, core router, or classic router).
    • Remote AS#—Remote AS number (defined on the WAN edge router or core router).
    • Local AS#—Prisma SD-WAN Data Center or Branch AS number.
    • Peer Type—Core router, WAN edge router, or classic router.
    • State—Information on BGP peer states. Status displays Uptime, indicating the time frame the peer is active and Downtime, indicating the time frame the peer is inactive, and the connection State of the BGP peer.
      Stats displays the statistics Sent and Received packets for each packet type. It also shows the number of prefixes accepted by the BGP peer, the dropped BGP connections, and established connections with the BGP peer.
    • Advertised Prefixes—Number of prefixes advertised to the BGP peers by the ION device. The data center ION advertises branch prefixes to classic and core peers but not the edge peers.
    • Reachable Prefixes—Number of prefixes that the ION device learns from the BGP peers, namely classic, core, or edge peer
    LAN Multicast
    The multicast routing information for the selected site displays the following:
    • Device—ION device name. Click to view the routing configuration of the device.
    • Source—Displays the source address of multicast traffic in the network.
    • Group—Displays the multicast group address.
    • RP Address—Displays the address of the Rendezvous Point (RP) in the network.
    • Flags—Indicate multicast message information.
      For device versions lower than 6.0.1
      • RP—Indicates Join/Prune messages propagated towards a shared RP tree.
      • WC—Indicates a Wild card entry (*, G).
      • SPT—Indicates Join/Prune messages propagated towards a source.
      • NEW—Indicates a new route entry.
      • CACHE—Indicates an entry cached in the kernel.
      • NULL—Indicates that information received should not be forwarded.
      For device versions 6.0.1 and higher
      • S: Sparse—Indicates that PIM Sparse mode is in use.
      • C: Connected—Indicates that a multicast receiver is directly connected to the branch ION device.
      • P: Pruned—Indicates Join/Prune messages propagated towards a source.
      • R: SGRpt Pruned—Indicates that traffic is being forwarded using the RP tree.
      • F: Register Flag—Indicates the traffic is arriving and set on a (*, G).
      • T: SPT—bit set—Indicates that at least one packet was received via the SPT.
    • Incoming Interface—Indicates the interface on which multicast traffic is received.
    • Outgoing Interfaces—Indicates the interfaces on which multicast traffic needs to be replicated.
    WAN Multicast
    The multicast routing information for the selected site displays the following:
    WAN Multicast is available from device version 6.0.1. You will be able to view WAN multicast statistics only after your tenant has been migrated to the new data lake infrastructure. If you cannot view statistics, contact the Palo Alto Networks Accounts Team.
    • Device—ION device name. Click to view the routing configuration of the device.
    • Source—Displays the source address of multicast traffic in the network.
    • Group—Displays the multicast group address.
    • Flags—Indicate multicast message information.
      • S: Sparse—Indicates that PIM Sparse mode is in use.
      • C: Connected—Indicates that a multicast receiver is directly connected to the branch ION device.
      • P: Pruned—Indicates Join/Prune messages propagated towards a source.
      • R: SGRpt Pruned—Indicates that traffic is being forwarded using the RP tree.
      • F: Register Flag—Indicates the traffic is arriving and set on a (*, G).
      • T: SPT—bit set—Indicates that at least one packet was received via the SPT.
    • Incoming Site/Interface—Indicates the interface on which multicast traffic is received.
    • Packets—Indicates the packet routing multicast module details.
    • Bytes—Indicates the byte routing multicast module details.
    • Outgoing Sites/Interfaces—Indicates the interfaces on which multicast traffic needs to be replicated.
      For Data center devices, the Outgoing Sites/Interfaces provides all the site information. Click View All to see the below details:
      • SECURE FABRIC LINK—Indicates the VPNs used between a branch and data center sites.
      • LAST ACTIVE AT—Indicates the last active date and time the multicast traffic was active.
      • TX PKTS—Indicates the number of multicast traffic packets transmitted from the site/interface.
      • TX BYTES—Indicates the volume of multicast traffic sent in bytes at the site/interface.
