If traffic is not moving properly, use the following procedure to determine the
issue.
Procedure
-
Ensure that all switch nodes in
the network operate with the most recent software release to support IP
Multicast over Fabric Connect:
-
Ensure that you create and
enable SPBM infrastructure globally.
-
Ensure that SPBM is
enabled globally:
-
Ensure that IS-IS is
enabled globally:
-
Ensure an SPBM instance
exists and at least one Backbone VLAN exists (B-VID). Also ensure
multicast is enabled:
-
Ensure that you enable the CFM
configuration.
-
Ensure a CFM
maintenance-association exists:
show cfm
maintenance-association
-
Ensure a CFM
maintenance-domain exists:
show cfm
maintenance-domain
-
Ensure a
maintenance-endpoint exists in the MEP ID column and is enabled in the
ADMIN column:
show cfm
maintenance-endpoint
-
Ensure the following on all BEBs
where you want IP Multicast over Fabric Connect. Ensure that you enable IP
Multicast over Fabric Connect globally:
-
On the VLANs that need Layer 3
VSN IP Multicast over Fabric Connect routing, create an IP interface on the VLAN
if one does not exist. The address should be on the same subnet as the IGMP
hosts connected to the VLAN. Also, ensure that you enable IP Multicast over
Fabric Connect. Create an IP interface on the VLAN and enable IP Multicast over
Fabric Connect.
-
Enter VLAN Interface Configuration
mode:
enable
configure
terminal
interface vlan <1–4059>
-
Create an IP interface on the
VLAN and enable IP Multicast over Fabric Connect:
ip address <A.B.C.D>
ip spb-multicast
enable
-
Ensure that you enable IGMP
Snooping on access Layer 2 switches to prevent flooding of multicast traffic to
non-receiver ports:
show ip igmp
snoop-trace
show ip igmp
interface
-
Ensure that the IGMP version
used by the multicast hosts and the Layer 2 switches outside the SPBM network is
the same as the IGMP version configured on the C-VLAN:
