Verifying Your Configuration
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 3 lists specific operational commands that can provide information about the IPTV network and the protocols that you configured on each video services router.
Table 3: Operational 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 |
|
show pim interfaces |
|
show pim join |
|
show pim neighbors show pim neighbors detail |
|
show pim rps | The PIM rendezvous point router is correct. |
show pim statistics | PIM statistics are in line with expectations. |
For additional information about these operational mode commands, see the JUNOS Routing Protocols and Policies Command Reference.
