Pim config question

[mike18]

Hi everyone,

Here is setup

Camera -------SW1--trunk ---SW2-------OSPF----SW3

Where SW1 has vlan 100 where cameras are connected but it has no PIM config .
SW1 and Sw2 are separated by the building and SW2 is layer 3 and it has PIM config and also PIM interfaces.
I am using PIM sparse mode need to confirm that current setup will work without any PIM config on switch 1 and I will manually config pim RP
on SW2?

Regards

Hi,
at SW2 and SW3 (layer 3) you need PIM at all necessary ip interfaces. Also at least one interface has to be canditate bootstrap router and candidate rendevouce point.
At SW1 (layer 2) you need following config:
> ip multicast status enable (bei R7/R8 admin-state enable)
> ip multicast querier-forwarding enable

Thanks for reply.

Current config on layer 3 switch 2 is

ip load pim
ip pim interface vlan-200
ip pim static-rp 236.0.0.0/8 10.2.10.1
ip pim static-rp 239.0.0.0/9 10.2.10.1
ip pim static-rp 239.0.1.0/24 10.2.10.1
ip pim static-rp 239.0.82.11/32 10.2.10.1
ip pim static-rp 239.36.159.0/24 10.2.10.1
ip pim static-rp 239.40.115.0/24 10.2.10.1
ip pim static-rp 239.51.0.0/16 10.2.10.1
ip pim static-rp 239.168.231.0/24 10.2.10.1
ip pim static-rp 239.168.232.0/24 10.2.10.1
ip pim static-rp 239.168.233.0/24 10.2.10.1
ip pim static-rp 239.225.33.0/24 10.2.10.1
ip pim static-rp 239.255.43.0/24 10.2.10.1
ip pim static-rp 239.255.89.0/24 10.2.10.1
ip pim static-rp 239.255.195.0/24 10.2.10.1
ip pim sparse status enable

Current config on switch does not show any interface which is configured for BSR.
but on this switch when I run the command

show ip pim bsr
BSR Address = 10.2.10.200,
BSR Priority = 200,
Hash Mask Length = 30,
Expiry Time = 00h:01m:42s,

so does it mean that this switch learn the BSR via multicast routing?

if the other PIM-switch does know the same BSR/RP than all is okey.
I prefer to use candidate BSR/RP instead of static config.

But I do see only one PIM interface. You have to activate PIM at the interfaces to the other PIM switch and ALSO to all mulicast server/clients.

So need to confirm this Switch2 knows the BSR via multicast routing from neighbor switch?

[silvio]

yes.
Is there any problem with mc-routing/switching at you?

Thanks a lot for clearing my doubts.
