Prevent an IPv6 Source from Registering with the RP
Prevent an IPv6 PIM Router from Processing an IPv6 Join
Multicast Traceroute
Multicast Traceroute is supported only on platform: e
MTRACE is an IGMP-based tool that prints that network path that a multicast packet takes from a source
to a destination, for a particular group. FTOS has mtrace client and mtrace transmit functionality.
• MTRACE Client—an mtrace client transmits mtrace queries and prints out the details received
responses.
• MTRACE Transit—when a Dell Force10 system is an intermediate router between the source and
destination in an MTRACE query, FTOS computes the RPF neighbor for the source, fills in the
request, and forwards the request to the RPF neighbor. While computing the RPF neighbor, static
mroutes and mBGP routes are preferred over unicast routes. When a Dell Force10 system is the last
hop to the destination, FTOS sends a response to the query.
Task Command Syntax Command Mode
Configured on the source DR, prevent the source DR from sending
register packets to the RP for specific sources and groups.
ipv6 pim register-filter access-list CONFIGURATION
FTOS(conf)#ipv6 pim register-filter REG-FIL_ACL
FTOS(conf)#ipv6 access-list REG-FIL_ACL
FTOS(conf-ipv6-acl)#deny ipv6 165:87:34::10/128 ff0e::225:1:2:0/112
FTOS(conf-ipv6-acl)#permit ipv6 any any
FTOS(conf-ipv6-acl)#exit
Task Command Syntax Command Mode
Permit or deny PIM Join/Prune messages on an
interface using an access list. This command prevents
the PIM-SM router from creating state based on
multicast source and/or group.
