The MTrace query type is specified. Correctly specifying the query type based on the network
situations helps to promptly and accurately trace the path. If the query type is not specified, the
system uses
multicast-tree
, by default.
l
all-router
: applies to the scenario where the current switch is linked to the destination host.
l
destination
: applies to the scenario where the unicast routes exist between the current
switch and the destination host.
l
last-hop
: applies to the scenario where the address of the last-hop switch is specified and
unicast routes exist between the current switch and the last-hop switch. When
last-hop
is
used, you must specify the IP address of the last-hop switch.
l
multicast-tree
: applies to the scenario where the current switch is on the multicast path from
the multicast source to the destination host.
CAUTION
If the
mtrace
command is run on a specified multicast VPN network,
mtrace-query-type
all-
router
cannot be configured.
Step 8
(Optional) Run:
mtrace-last-hop-address
ipv4
ip-address
The IP address of the last-hop switch is specified.
Step 9
(Optional) Run:
source-address
ipv4
ip-address
The source address of the IGMP-Tracert-Query packet, which must be the address of the local
interface, is configured. If
multicast-tree
is applied, this step is skipped.
Step 10
Run:
quit
Exit from the NQA test instance view.
