Description
The mfib-ping utility determines the list of SAPs which egress a certain IP multicast stream
(identified by source unicast and destination multicast IP addresses) within a VPLS service.
An mfib-ping packet is always sent via the data plane.
An mfib-ping is forwarded across the VPLS following the MFIB. If an entry for the specified source
unicast and destination multicast IP addresses exist in the MFIB for that VPLS, then the packet is
forwarded along those paths, provided they are active. A response is generated only when there is an
egress SAP binding for the specified IP multicast stream.
An mfib-ping reply can be sent using the data plane or the control plane. The return-control option
specifies the reply be sent using the control plane. If return-control is not specified, the reply is sent
using the data plane.
Parameters
service service-id — The service ID of the VPLS to diagnose or manage.
source src-ip — The source IP address for the OAM request.
destination mcast-address — The destination multicast address for the OAM request.
size size — The multicast OAM request packet size in octets, expressed as a decimal integer. The
ttl vc-label-ttl — The TTL value in the VC label for the OAM request, expressed as a decimal
return-control — Specifies the OAM reply has to be sent using the control plane instead of the data
interval interval — The interval parameter in seconds, expressed as a decimal integer. This

request payload is padded to the specified size with a 6 byte PAD header and a byte payload of
0xAA as necessary. If the octet size specified is less than the minimum packet, the minimum
sized packet necessary to send the request is used.
