Mulitcasting issues

                   Ok i am seeting up SCCM server (10.1.1.37) for my work place and multicasting the images was one of the main feture requests i got. I have it up and running but it is not running well.  i Have 4 sites all connected via a static route over fiber.  One the main sites router , its a 6509 that say basically if the traffiic goes to the internet send it out the gateway of last resport( which goes to an internet facing 6509) .  Anything that internal 10.x.x.x figure where it goes and send it there. When it was running the other day and one system had an error all of the traffic to the internet was slowed ...a lot. IM trying to figure out why im getting - numbers in my rate, when the server is directly connected to the switch it self.

on the internal router lets call it 10.1.1.253 here are my multicast settings

!

ip flow-cache timeout active 1

ip multicast-routing

no ip domain-lookup

ip domain-name

ip name-server 10.x.x.x.

ipv6 mfib hardware-switching replication-mode ingress

mls ip multicast flow-stat-timer 9

no mls flow ip

no mls flow ipv6

mls qos map cos-dscp 0 8 16 26 32 46 48 56

mls qos map ip-prec-dscp 0 8 16 26 32 46 48 56

mls qos

no mls acl tcam share-global

mls cef error action freeze

!

ip pim rp-address 10.1.1.253

sample vlan is this

!

interface Vlan5

ip address 10.1.5.253 255.255.255.0

ip helper-address 10.1.1.11

ip pim sparse-dense-mode

no ip mroute-cache

end

on all the other routers i also have

ip pim rp-address 10.1.1.253.

When my multicast is running from the sccm i ran 3 commands

show ip mroute active

Anyone have any ideas?

Mulitcasting issues

What was the error? Was it on the switch? Did you check CPU levels?

Your output looks fine - only thing I recommend changing is the mroute-cache - it must be enabled.

Also, please provide the output from 'show ip pim interface count'
