Hi Jeff,
I still did not have opportunity to test it over L3. However, I tested
it over L2 VPNs. The result was pretty good, specially when using the
more complex algorithm available in the command ip multicast
multipath
Each IPTV program took a different interface when using the following:
-Different sources and multicast group
-Same source and different multicast group
I believe the limitation advised in Cisco page were removed, or I am not
using exactly the same PFC described in the restriction.
Br,
Alaerte

Hi Alaerte,
Would be interested in your test results.
Thanks,
Jeff

Thanks Oli.
I will test today on PFC3xx with SRB2 and post the result.
Br,

Hi,
PIM considers source of multicast to perform load splitting when the
command ip multicast multipath is entered. When using multicast
over
L3 MPLS VPN, the source IP is the IP of PEx for any customer group
connected to PEx.
Any way to overcome this limitation and achieve load splitting of
multicast over L3 MPLS VPN?
For example, consider this scenario:
Sender for group G1 and
G2---CE1-PE1--P1-PE2CE2receiver of G1 and G2
| |
|___P2__|
The goal is having one G1 taking path PE1--P1--PE2 and G2 taking
path PE1--P2--PE2.
(but without using GRE encapsulation to have multicast encapsulated
into unicast)
12.2SRB for the 7600 introduced ip multicast multipath s-g-hash
basic
which allows you to do the hash on source+group.. Platform support for
this is still limited, not sure about your environment.
