In short it means that first hop routers (CE1 and CE3) receive IGMPv3 join where both source address and multicast group are specified. mVPN involves routes Type 1, 3 and 7 in this case.
Route types
| Type | Name | Type | Definition |
|---|---|---|---|
| Type 1 | Intra-AS I-PMSI A-D route | AD | |
| Type 2 | Inter-AS I-PMSI A-D route | AD | |
| Type 3 | S-PMSI A-D route | AD | |
| Type 4 | Leaf A-D route | AD | |
| Type 5 | Source Active A-D route | AD | |
| Type 6 | Shared Tree Join route | C-multicast | |
| Type 7 | Source Tree Join route | C-multicast |
All PEs are announcing Type 1 and Type 3.

Let's follow the data-plane for group 232.1.1.1 starting from ingress PE2 to P and lastly to PE1 and PE3. Most interesting output is from P. As you can see P router replicates traffic which arrives with label 24003 to both PE1 and PE3. That's the heart of mVPN MLDP data-plane behaviour.

Following output show what happens on P router when there's only one receiver behind PE1. CE3 is not requesting 232.1.1.1. So now P router does not replicate traffic ingressing the router with label 24003.

Actually there's nothing interesting in this case. Ingress PE has no parties interested in receiving 232.1.1.1. Thus it just drops incoming stream.
- Check CLI
- Get a bit deeper.

Several vendors depending on a software version are using pre-RFC encoding for C-Mcast Import RT. In this case you won't find a correct extended community in VPNv4 updates. Instead there will be community which Cisco interprets as L2VPN AGI.
Below you can find CLI to switch to RFC encoding.

Extended community: VRF Route Import:10.1.100.2:2 Source AS:1:0 RT:1:1RFC6625 defines a new zero-length source and group addresses for mVPN Type 3 BGP Update.
This document specifies that a "zero-length" source
or group represents the corresponding wildcard. Specifically,
- A source wildcard is encoded as a zero-length source field.
That is, the "multicast source length" field contains the value
0x00, and the "multicast source" field is omitted.
- A group wildcard is encoded as a zero-length group field. That
is, the "multicast group length" field contains the value 0x00,
and the "multicast group" field is omitted.
172.16.1.44 (NCS5500) originates mVPN Type 3 and advertises it directly to 172.16.1.44 (NCS5500).

- Juniper RR receives the correct mVPN Type 3 Wildcard update with
Multicast Source LengthandMulticast Group Lengthset to0x00.Multicast Source AddressandMulticast Group Addressare omitted. - Juniper reflects a modified update with
Multicast Source AddressandMulticast Group Addressfields set to0.0.0.0. - To reflect the changed NRLI length Juniper adjusts the
ATTRIBUTE LENGTHandNLRI Lengthfields accordingly. - NCS5500 receives the corrupted update and reads it based on RFC6625 encoding.
