How to multicast Symantec Ghost over a FWSM

Hello

I just can't get multicast with Symantec Ghost to work over the FWSM with software version 3.1.3.

The ghost server is in a Vlan (Vlan 200) protected by the FWSM, the clients which should be ghosted are not behind the FWSM in a different Vlan (Vlan 15).

I configure the FWSM with the Security Manager CSM 3.1.

How should the correct config look?

This is what I found in the FWSM config which is probably connected to the Multicast:

multicast-routing

interface Vlan200

nameif server

security-level 50

ip address a.a.200.1 255.255.252.0 standby a.a.200.2

igmp forward interface clients

mroute a.a.224.10 255.255.255.255 transit1

mroute a.a.201.66 255.255.255.255 dozpers

Maybe there are also other lines which I missed.

Anyway, I can see the clients on the ghost server, but if I start the push, then the clients don't recieve the packets.

The hardware is a Cat 6500 with IOS 12.2 and some Gig Ethernet cards where switchs are connected to.

Thanks,

Patrick

Re: How to multicast Symantec Ghost over a FWSM

Does the problem lie only with Symantec Ghost.See if IGMP is enabled on the switch and also on the entire network.Also if multicasting works throughout the network.

Re: How to multicast Symantec Ghost over a FWSM

Hi smahbub

Multicasting works as long as the ghost server is on the same VLAN as the clients.

The problem starts when it's being routed.

Currently I can only test it routed through the FWSM.

Re: How to multicast Symantec Ghost over a FWSM

I could solve it now with the help of a CCIE :)

Here the solution (just the config which was wrong or missing).

On the router:

int vlan22

ip pim sparse-dense-mode

int vlan24

ip pim sparse-dense-mode

int vlan32

ip pim sparse-dense-mode

int vlan40

ip pim sparse-dense-mode

int vlan192

ip pim sparse-dense-mode

int vlan220

ip pim sparse-dense-mode

int vlan224

ip pim sparse-dense-mode

int vlan229

ip pim sparse-dense-mode

int vlan900

ip pim sparse-dense-mode

ip pim rp-address 192.168.10.1

And the FWSM:

access-list transit1 remark Multicast Temp

access-list transit1 permit ip any host 229.55.150.208

access-list transit1 permit ip any host a.a.224.10

access-list transit1 permit ip any 224.77.0.0 255.255.0.0

access-list transit1 permit ip any a.a.24.0 255.255.252.0

interface Vlan200

no igmp forward interface transit1

exit

no mroute a.a.201.66 255.255.255.255 dozpers

no mroute a.a.224.10 255.255.255.255 transit1

pim old-register-checksum

pim rp-address 192.168.10.1 bidir

Hope this will help other people!

Re: How to multicast Symantec Ghost over a FWSM

I'm still gnashing my teeth with keeping Ghost from flooding.

I've got it to work semi-acceptably enabling ip multicast-routing and ip pim dense mode on the desired vlan.

Multicast Vlan Registration (see 20-13 c3550 guide doc#78-11194-09) looked promising, but I was unable to get it right: all ports still lit up and ground to halt.

Have you considered/tried/had any luck with this?

Thanks, Steve
