Enable PIM on the Firewall, Firewall Cluster, or Virtual Firewall

You must enable PIM for the Firewall, Firewall Cluster, or Virtual Firewall in the Engine Editor.

For more details about the product and how to configure features, click Help or press F1.

Steps

  1. Select Configuration.
  2. Right-click an engine, then select Edit <element type>.
  3. In the navigation pane on the left, browse to Routing > Multicast Routing.
  4. From the Multicast Routing Mode drop-down list, select PIM.
  5. If you do not want to use the default PIM Profile, select another PIM Profile element from the PIM Profile drop-down list.
  6. (Optional, PIM-SM only) Expand the Bootstrap Settings section, then modify the settings.
  7. Click Save.

Next steps

You are now ready to add a PIM Interface Settings element to the engine on the Routing branch.

Engine Editor > Routing > Multicast Routing

Use this branch to define static multicast, IGMP-based multicast forwarding, or PIM dynamic routing. Only IPv4 addresses are supported.

Option Definition
Multicast Routing Mode Specifies how the Engine routes multicast traffic.
  • None — Disables multicast routing.
  • Static — Enables options that allow you to add static routes for multicast traffic.
  • IGMP Proxy — Enables options that allow you to use the Engine for IGMP-based multicast forwarding.
  • PIM — Enables options that allow you to use the Engine for dynamic routing using PIM.
Option Definition
When Multicast Routing Mode is Static

Click Add to add a row to the table, or Remove to remove the selected row.
Source Interface Select the interface to use for multicast routing.
Source IP Address Enter the unicast IP address of the multicast source.
Destination IP Address Enter the multicast destination IP address. The destination address must be within the multicast range of 224.0.0.0 to 239.255.255.255.
Destination Interface Right-click Destination Interface, then select Edit Destination Interface to select the interfaces where you want this multicast traffic forwarded.

(Optional)

 A comment for your own reference.
Option Definition
When Multicast Routing Mode is IGMP Proxy
Upstream Interface Select the interface to use as the upstream interface. If the multicast servers and the hosts are in the local networks, or if you want to limit the multicast to the local networks, it is not necessary to define the upstream interface. In that case, leave Not Set selected.
Upstream IGMP Version Select the IGMP version according to the upstream network environment. The default IGMP version is version 3.
Downstream Interfaces table

Click Add to add a row to the table, or Remove to remove the selected row.
Interface Select the downstream interfaces.
IGMP Querier Settings Select an IGMP Querier Settings element according to the downstream network environment. The element defines the IGMP version and query parameters.
Option Definition
When Multicast Routing Mode is PIM
PIM Profile Select a PIM Profile to use. The profile contains the multicast groups and determines the PIM mode that is used.
Multicast Routing Preference
Note: This option is not supported in this version of Engine.
The routing table is used to specify reverse path forwarding (RPF) information whenever multicast traffic from source addresses uses a different path than unicast traffic from the same source address.
  • Prefer Best Match — The RPF lookup prefers the best match based on both the default routing table and the Multicast routing (mroute) table.
  • Prefer mroute — The RPF lookup uses the mroute table. If the mroute table cannot be used, the default routing table is used.
Bootstrap Settings — see RFC 5059 for more information.
RP Candidate If you want to use the firewall as a rendezvous point (RP) candidate, select an IP address. Otherwise, select Not a Candidate.
RP Priority Enter a value for the RP priority.
Multicast Groups Add the multicast IPv4 networks for which the firewall acts as an RP candidate. Click Add to add a row to the table, or Remove to remove the selected row.
BSR Candidate If you want to use the firewall as a bootstrap router (BSR) candidate, select an IP address. Otherwise, select Not a Candidate.
BSR Priority Enter a value for the BSR priority.
