PIM

Hello.

How to view pim join? I.e. how do I know if the router is requesting any groups from me(RP)? I want to see the ip-address of the pim-router and the groups.

My rendezvous point is the X480-24x with ExtremeXOS15.5.5.2.

Hi gorn,

Her from my cheat sheet:

#VERIFY

show vlan 'mop & sc flag

show pim

show pim rp-set

show pim rp-set <ip of Group from policy file>

show pim cache 'show groups available in the network

show vlan 'mop & sc flag - I don't have such a command.
show pim - there are no groups and no router that requests the stream. Here are listed pim-interfaces, timers, BSRs...
show pim rp-set - I don't need information about RP.
show pim cache - it just lists all the available groups.

I'm looking for a way to see on the RP that a particular router has requested specific groups; that the client(PIM-router) asks for TV channels(groups), ip-address+groups.

The closest thing I found is sh pim snooping vlan. If it's on. There are groups and by DownPort
you can guess, if the topology allows, who exactly requested them. But this is not so convenient and there is no ip-address of the requestor.

gorn,

mop and sc are flags you should look for in the output of show vlan

Maybe

show ip pim rp

show ip pim rp mapping

are the commands you are looking for

Ok, I understood: (c) 802.1ad customer VLAN (m) IPmc Forwarding Enabled, (o) OSPF Enabled, (p) PIM Enabled, (s) Sub-VLAN. This is not what I want.

switch# show ip ?

Thank you very much for your support. It seems the only way is to look at arp’s, pim snooping, ports, mac-addresses and compare it.
After all, RP receives all join-messages and stores them in the cache. I was hoping we could have a look at them.
