You can use several commands to verify that the
IPTV network is functioning and to monitor its status.
Verifying Connectivity
When you configure your IPTV network, we recommend
that you verify connectivity between routers (VSR1 and VSR2) and between
each router and certain devices using the ping command.
The format for the ping command is as
follows:
ping host source source-address
host—IP address
of the device or interface to which you want to issue the ping command.
source source-address—IP address of the outgoing interface.
To verify connectivity:
Issue the ping command from the access interface
on each router to the loopback interface of the redundant router.
Issue the ping command from each metro and core
interface on each router to the metro and core interface on the redundant
router.
Issue the ping command from the loopback interface
of each router to the DHCP server.
Using Operational Commands
You can use various operational commands to obtain
information about the IPTV network and to verify that the network
is operating properly. Table 4 lists specific
operational commands that can provide information about the IPTV network
and the protocols that you configured on each video services router.

Commands for Network Verification
Operational Command
Purpose
show dhcp relay binding
The expected DHCP address bindings appear in the Dynamic Host
Configuration Protocol (DHCP) client table.
show dhcp relay statistics
DHCP relay statistics are in line with expectations.
show igmp group
IGMP group membership is functioning as expected.
show igmp interface
The status of each configured IGMP interface is operational
(up).
The expected number of groups appears on each IGMP interface.
Promiscuous mode is enabled (on) for IGMP unnumbered interfaces.
show pim interfaces
The status of each PIM interface is operational (up).
Each interface is running sparse mode.
show pim join
PIM group joins are occurring as expected.
Each join is receiving sparse mode entries.
show pim neighbors
show pim neighbors detail
PIM is establishing neighbor adjacencies correctly.
BFD is enabled.
show pim rps
The PIM rendezvous point router is correct.
show pim statistics
PIM statistics are in line with expectations.

mode commands, see the JUNOS Routing Protocols and Policies
Command Reference.
