Summit x460 and PIM IGMP

Lebed_Sergey — Sat, 09 May 2015 21:00:00 GMT

I have troble with multicat routing from VLAN with Multicast server to VLAN with subscribers.

( REC_VLAN - Subscribers ) - x460 - ( SEND_VLAN - Multicast server )

System Type: X460-24t
Image Selected: primary
Primary ver: 15.5.3.4 patch1-6 Enabled License Level: Core
Here my config:

configure vlan mgmt_switch_core tag 104create vlan "REC_VLAN"
configure vlan REC_VLAN tag 109
create vlan "SEND_VLAN"
configure vlan SEND_VLAN tag 2001
configure vlan REC_VLAN add ports 24 tagged
configure vlan SEND_VLAN add ports 8 untagged
configure vlan SEND_VLAN ipaddress 10.3.0.2 255.255.255.252
enable ipforwarding vlan SEND_VLAN
configure vlan REC_VLAN ipaddress 10.3.3.5 255.255.255.252
enable ipforwarding vlan REC_VLAN
enable ipmcforwarding vlan "REC_VLAN"
enable ipmcforwarding vlan "SEND_VLAN"
configure igmp snooping "REC_VLAN" ports 24 add static router
configure pim add vlan "SEND_VLAN" sparse
configure pim crp vlan "SEND_VLAN" "MCAST_TEST" 100
configure pim add vlan "REC_VLAN" sparse passive
configure pim vlan "REC_VLAN" dr-priority 100
enable pim
configure pim crp static 10.3.0.2 "MCAST_TEST" 100MCAST_TEST:
entry m {
if match any { }
then {
nlri 225.1.1.0/24 ;
}
} On egress vlan I can see subscribers and static router:

show igmp snooping "REC_VLAN"
Router Timeout : 260 sec
Host Timeout : 260 sec
Igmp Snooping Fast Leave Time : 1000 ms
VLAN REC_VLAN (109) Snooping=Enabled
Port Host Subscribed Age Group-Limit
24 10.3.3.6 225.2.1.1 60 0
24 10.3.3.6 239.255.255.250 65 0
24 10.3.3.5 All Groups(s) 0 0

On ingress vlan I can see server:
show igmp snooping "SEND_VLAN"Router Timeout : 260 sec
Host Timeout : 260 sec
Igmp Snooping Fast Leave Time : 1000 ms
VLAN SEND_VLAN (2001) Snooping=Enabled
Group Sender Age
225.2.1.1 10.3.0.1 0
1 Incoming multicast streams

Multicast traffic present on ingress port:

But it doesn't present on egress port:

What I need to do for multicast routing between REC_VLAN and SEND_VLAN.
I don't need MVR, because I have two multicast upstreems (LOCAL - SEND_VLAN) and from neighbor AS.

Hi,

check TTL for multicast streams.

TTL = 32. This multicast server (in SEND_VLAN) works fine in another multihop RPT

Hi Lebed,

On ingress vlan I can see server:
show igmp snooping "SEND_VLAN"Router Timeout : 260 sec
Host Timeout : 260 sec
Igmp Snooping Fast Leave Time : 1000 ms
VLAN SEND_VLAN (2001) Snooping=Enabled
Group Sender Age
225.2.1.1 10.3.0.1 0
1 Incoming multicast streams

Multicast server is sending Multicast group IP 225.2.1.1 but in policy you mentioned nlri 225.1.1.0/24.

Please edit the MCAST_TEST and mentioned the 225.2.1.1/24.

I hope this would resolve the issue.

After several attempts I made so stupid mistake. Thank you!

Just reading this thread. I was wondering why you needed a policy at all for this to work?

because in production I have 2 multicast upstream's, with different multicast groups:

show pim rp-set
Group Mask C-RP Origin Priority Timeout
239.13.1.0 255.255.254.0 x.x.x.254 static 100 0
225.1.1.0 255.255.255.0 10.3.0.1 static 100 0
225.50.50.0 255.255.255.0 x.x.x.254 static 100 0
234.5.2.0 255.255.255.128 x.x.x.254 static 100 0
224.2.2.0 255.255.255.224 x.x.x.254 static 100 0
239.60.8.1 255.255.255.255 x.x.x.254 static 100 0and RP for them defined by policy
