ACI L3 Multicast Troubleshoot – Part-3: Source and Receiver inside ACI – Topology 2

Topology:


I- Receiver sends out IGMP Report

In this first, we focus on Receiver side and how shared tree is formed (no traffic from source yet):


1- Receiver sends IGMP Join:

Upon receive of the IGMP join from receiver for the group 239.251.1.1, IGMP entry added to leaf-3-4:

leaf3# show ip igmp groups vrf bameur_MC:VRF-MC3
Type: S - Static, D - Dynamic, L - Local, T - SSM Translated
IGMP Connected Group Membership for VRF "bameur_MC:VRF-MC3"

(*,G) tree installed to leaf-3-4 (where receiver resides):

    Transport protocol is in VRF "bameur_MC:VRF-MC3"
    Tunnel protocol/transport is ivxlan
    Tunnel source 127.0.0.100/32
    Tunnel destination 225.1.192.48/32Code language: PHP (php)

RPF pointing to root of the shared: the RP 192.168.30.10 (RPF neighbor to reach RP is BL PTEP 10.0.48.64)

Outgoing Interface: pointing to the BD VLAN of the Receiver EP


2- IGMP Join interest Published to COOP:

After receiving interest from the receiver EP via IGMP Join, Leaf-3-4 will publish it to COOP:

4- Stripe Winner Border leaf install (*,G):

The stripe winner is responsible for sending PIM joins back to the source/RP

Checking the stripe winner via command below: we can see that we have 2 BL and winner for the group 239.251.1.1 (based on hash) is BL with Router-id 1.1.1.1, which is leaf-1 in our example:

leaf-1# show ip pim internal stripe-winner 239.251.1.1 vrf bameur_MC:VRF-MC3
PIM Stripe Winner info for VRF "bameur_MC:VRF-MC3" (BL count: 2)
(*, 239.251.1.1)
BLs:

1.1.1.1  hash: 1281198598 (local)
      2.2.2.2  hash: 961945459
Winner: 1.1.1.1 best_hash: 1281198598Code language: CSS (css)


As a result , leaf-1 (Stripe winner) will install (*,G) in MRIB and send (*,G) toward the RP:

leaf-1# show ip mroute vrf bameur_MC:VRF-MC3

As expected, nothing installed in mRIB for the non stripe winner BL:

5-Stripe winner leaf-1 sends (*,G) PIM join to RP:

The RP receive the (*,G) from the Stripe winner and build the shared tree to the receiver:

RP# show ip mroute

  Incoming interface: loopback155, RPF nbr: 192.168.30.10
  Outgoing interface list: (count: 1)
    Ethernet1/3.1058, uptime: 00:23:41, pim

Outgoing interface pointing to leaf-1, from where the (*,G) join was received.


II- Source starts sending Multicast traffic

6-Source starts sending Multicast traffic for the group

Source 10.29.1.10 located on leaf-5-6 starts sending multicast traffic for the group 239.251.1.1:

EP Flags : local|vPC|IP|MAC|sclass|timer|


7- FHMR install (S,G):

Source tree state installed in mRIB:

leaf6# show ip mroute vrf bameur_MC:VRF-MC3

(10.29.1.10/32, 239.251.1.1/32), uptime: 00:28:59, ip pim 
  Incoming interface: Tunnel17, RPF nbr: 10.0.128.65 (pervasive)
  Outgoing interface list: (count: 0)


8- FHMR Send PIM Register to RP:

On the FHMR, the RP subnet must be reachable, in our example, we have a route for it pointing to the PTEP of the border leafs: Leaf-1 and Leaf-2:

leaf6# show ip route 192.168.30.10 vrf bameur_MC:VRF-MC3
IP Route Table for VRF "bameur_MC:VRF-MC3"
'*' denotes best ucast next-hop
'**' denotes best mcast next-hop
'[x/y]' denotes [preference/metric]
'%<string>' in via output denotes VRF <string>

192.168.30.10/32, ubest/mbest: 2/0
    *via 10.0.48.65%overlay-1, [200/0], 09:22:36, bgp-65001, internal, tag 65033
         recursive next hop: 10.0.48.65/32%overlay-1
    *via 10.0.48.64%overlay-1, [200/0], 09:22:36, bgp-65001, internal, tag 65033
         recursive next hop: 10.0.48.64/32%overlay-1Code language: PHP (php)

Like any unicast traffic, we have ECMP for the destination and based on hash, a next-hop via a BL is picked:

The FHMR leaf-6, sends PIM Register as unicast toward the RP:

leaf6# show ip pim internal event-history null-register | grep 239.251.1.1 | grep "pim_send_null_register" | more
2024-04-08T09:47:02.014681000+02:00 pim [24758]: TID 25073:pim_send_null_register:1295:(bameur_MC:VRF-MC3-base) Send Null Register to RP 192.168.30.10 for 
(10.29.1.10/32, 239.251.1.1/32)Code language: PHP (php)


9- RP install (S,G) in mRIB and send (S,G) to the source

The RP install (S,G) and starts joining the source tree:

RP# show ip mroute 

(10.29.1.10/32, 239.251.1.1/32), uptime: 00:43:07, pim mrib ip 
  Incoming interface: Ethernet1/3.1058, RPF nbr: 192.168.50.1, internal
  Outgoing interface list: (count: 0)


The RP sends (S,G) Join to the source.

From the unicast routing table of RP, I see that the route to the source subnet is via leaf-1:

RP# show ip route vrf bameur_mc
IP Route Table for VRF "bameur_mc"
'*' denotes best ucast next-hop
'**' denotes best mcast next-hop
'[x/y]' denotes [preference/metric]
'%<string>' in via output denotes VRF <string>

10.29.1.0/24, ubest/mbest: 1/0
    *via 192.168.50.1, [20/0], 09:29:39, bgp-65033, external, tag 65001Code language: PHP (php)


10- Leaf-1 receive the (S,G) join from the RP

leaf1# show ip pim internal event-history pim-internal | grep 10.29.1.10 | grep receive 
2024-04-08T10:12:40.443791000+02:00 pim [4016]: TID 4463:pim_receive_join:1722:(bameur_MC:VRF-MC3-base) Route (10.29.1.10/32, 239.251.1.1/32) in PIM but not in MRIB, so force_add it to MRIB
2024-04-08T10:12:40.443782000+02:00 pim [4016]: TID 4463:pim_receive_join:1566:(bameur_MC:VRF-MC3-base) Create route for (10.29.1.10/32, 239.251.1.1/32)Code language: PHP (php)


Leaf-1 install (S,G):

Leaf-1 act the LHMR and install the (S,G) tree:

Incoming and outgoing interfaces pointing to the fabric since source in ACI:

leaf1# show ip mroute vrf bameur_MC:VRF-MC3

(*, 239.251.1.1/32), uptime: 01:47:23, ngmvpn ip pim 
  Incoming interface: Ethernet1/19.187, RPF nbr: 192.168.50.2

  Outgoing interface list: (count: 1)
    Tunnel17, uptime: 01:21:00, mrib, (RPF)


Once the BL Leaf-1 receives multicast traffic (via VRF GiPO, through FTAG tree) from the source, it send a Prune to the RP:

RP# show ip mroute 

(*, 239.251.1.1/32), uptime: 01:58:46, pim ip

Leaf-6 hit the (S,G) entry:

(10.29.1.10/32, 239.251.1.1/32), uptime: 00:21:20, ip pim 
  Incoming interface: Tunnel17, RPF nbr: 10.0.128.65 (pervasive)
  Outgoing interface list: (count: 0)


In fact, to see to the complete status, we check the FIB:

leaf6# show forwarding distribution multicast route vrf bameur_MC:VRF-MC3 group 239.251.1.1

  (10.29.1.10/32, 239.251.1.1/32), RPF Interface: Tunnel17, flags: O
    Received Packets: 24 Bytes: 1560 
    Number of Outgoing Interfaces: 1
    Outgoing Interface List Index: 8206
      Tunnel17


As a result, the traffic forwarded to the fabric via tunnel 17 with destination as VRF GiPo:

leaf6# show interface tunnel 17
Tunnel17 is up
    MTU 9000 bytes, BW 9 Kbit
    Transport protocol is in VRF "bameur_MC:VRF-MC3"
    Tunnel protocol/transport ivxlan
    Tunnel source 127.0.0.100, destination 225.1.192.48Code language: PHP (php)


The packet is distributed through the FTAG tree ID 10:

module-1(DBG-elam-insel6)# ereport  | grep FTAG
