show evpn oism spmsi-ad
Syntax
show evpn oism spmsi-ad <extensive> <group multicast-group-address> <l3-context l3-vrf-name> <source multicast-source-address>
Description
Display multicast source and group (S,G) information corresponding to Selective P-router Multicast Service Interface (S-PMSI) Auto-Discovery (A-D) routes in an EVPN-VXLAN network running enhanced optimized intersubnet multicast (OISM). Enhanced OISM devices use S-PMSI A-D routes to perform PIM source registration only for multicast sources inside the EVPN-VXLAN network.
See PIM Registration with Enhanced OISM for Internal Sources Based on EVPN Type 10 S-PMSI A-D Routes for details on how OISM leaf devices use these routes.
With enhanced OISM, also called the asymmetric bridge domains design, the PEG devices receive traffic on the OISM supplemental bridge domain (SBD) from both external and internal multicast sources. Because OISM PEG devices should only perform PIM registration to the PIM rendezvous point (RP) for internal sources, the enhanced OISM design must distinguish between internal and external multicast sources. With enhanced OISM, the ingress leaf devices advertise S-PMSI A-D routes for internal multicast sources. The PEG devices then send a PIM register to the PIM RP only for the sources that correspond to received S-PMSI A-D routes.
You can see more details about received EVPN Type 10 S-PMSI A-D route advertisements in
the EVPN instance multicast routing table using show route table commands
such as the following:
user@host> show route table default-switch.evpn.0 match-prefix 10*
Or:
user@host> show route table evpn-instance-name.evpn-mcsn.1 match 10* extensive
Options
Basic brief output (no extensive option) |
Display summary output for all Layer 3 (L3) virtual routing and forwarding (VRF) instances and all EVPN instances. |
extensive |
(Optional) Display more detailed output. |
group multicast-group-address |
(Optional) Display information for the specified multicast group. |
l3-context l3-vrf-name |
(Optional) Display information only for the specified Layer 3 virtual routing and forwarding (VRF) routing instance. Without this option, this command displays information for all Layer 3 VRF routing instances where you enabled OISM. |
source multicast-source-address |
(Optional) Display information for the specified multicast source address. |
