Enhanced PIM support for VRFs 7.6.1
|
This information is also available in the FortiOS 7.6 Administration Guide: |
PIM now supports all VRFs (up to 511) and is aware of IPv4 multicast routing and forwarding over a single overlay, enhancing network scalability and flexibility compared to the previous VRF 0-only support.
Per-VRF commands have been included for multicast routing, as follows:
config router multicast
config pim-sm-global-vrf
edit <vrf>
set bsr-candidate {enable | disable}
set bsr-interface <interface>
set bsr-priority <0-255, default = 0>
set bsr-hash <0-32, default = 10>
set bsr-allow-quick-refresh {enable | disable}
set cisco-crp-prefix {enable | disable}
config rp-address
edit <id>
set ip-address <RP router IP address>
set group <access list name>
next
end
next
end
end
VRF support has also been included in the following diagnose, get, and execute commands:
diagnose ip multicast mfc-add diagnose ip multicast mfc-del diagnose vpn mr|mr6 add diagnose vpn mr|mr6 del get router info multicast igmp groups get router info multicast igmp groups-detail get router info multicast table get router info multicast table-count get router info multicast pim sparse-mode bsr-info get router info multicast pim sparse-mode rp-mapping get router info multicast pim sparse-mode next-hop get router info multicast pim sparse-mode table execute mrouter clear multicast-routes execute mrouter clear sparse-mode-bsr execute mrouter clear sparse-routes execute mrouter clear statistics
Example
This example uses the following topology:
In this example, the multicast server:
-
Sends out multicast traffic 225.1.1.1 from 22.1.1.22 in VRF1.
-
Sends out multicast traffic 225.1.1.2 from 22.1.1.55 in VRF2.
To verify VRF in IPv4 multicast routing:
-
Review the sniffer information:
-
The VRF1 client can receive 225.1.1.1 and cannot receive 225.1.1.2:
24.872130 vd33-vlan33 in 22.1.1.22 -> 225.1.1.1: icmp: echo request 25.872117 vd3-vlan33 out 22.1.1.22 -> 225.1.1.1: icmp: echo request 25.872123 vd33-vlan33 in 22.1.1.22 -> 225.1.1.1: icmp: echo request 26.872131 vd3-vlan33 out 22.1.1.22 -> 225.1.1.1: icmp: echo request 26.872137 vd33-vlan33 in 22.1.1.22 -> 225.1.1.1: icmp: echo request
-
The VRF2 client can receive 225.1.1.2 and cannot receive 225.1.1.1:
