The Advanced Routing Engine allows you to configure IPv4 multicast routing
for a logical router. Recall that PIM checks whether the firewall received the
packets on the same interface that the firewall uses to send unicast packets back to
the source, by checking the unicast RIB.
In a topology where you want unicast packets to take a different route from multicast
packets, you can configure an mroute. An mroute is static unicast route that points
to a multicast source; the mroute is stored in the multicast RIB (MRIB). PIM uses
the mroute for the RPF checks, rather than using the unicast RIB for RPF checks.
Whether PIM uses the MRIB or URIB for RPF checking depends on the RPF lookup mode
configured for PIM. During RPF checks, the mroute used is the one with the longest
prefix match.
An mroute is useful, for example, when some devices along the path do not support
multicast routing, so a tunnel is used to connect multicast routers.
PAN-OS
Create an mroute for IPv4 multicast on a logical router on a PAN-OS
firewall.
Create an mroute (static route) for IPv4 multicast on a logical router on a PAN-OS
firewall.
- Configure a Logical Router.Select and select a logical router.Select Multicast and enable multicast protocol.Create an mroute.
- Select Static and Add an mroute by Name. The name must start with an alphanumeric character, underscore (_), or hyphen (-), and contain zero or more alphanumeric characters, underscore, or hyphen. No dot (.) or space is allowed.
