Site Preparation for 3CMedia Multicast Streams

Send Request to CENIC for Enabling Multicast
First, your network administrator must submit a request to CENIC informing them that you would like to receive the 3CMedia Solutions multicast feeds and ask to have multicast enabled for your campus.  CENIC will make sure your edge router is properly configured.  Please submit your request to CENIC by emailing noc@cenic.org and copy crodriguez@palomar.edu and pcerda@palomar.edu.

CENIC Multicast-Related Requests
CENIC supports multicast on both the DC and HPR backbone networks. The process for enabling multicast is as follows:

1. Submit your request via e-mail to noc@cenic.org. Your request will be acknowledged and assigned to a CENIC Network Engineer.

2. The CENIC Network Engineer will coordinate with the campus network contact on multicast configuration tasks.

CENIC is responsible for multicast configuration on backbone equipment. Your site or campus network administrator is responsible for LAN multicast configuration, including PIM-SM, MSDP, BGP/MBGP, and RP.

Configure your Network
Second, follow the configuration instructions that best fit your network application depending on whether you are or will be doing multicast within your campus network, or the quick and simple configuration if this is the only two multicast streams you plan on receiving.

3CMedia Multicast feeds only-
This will need to be repeated for every router within the network that is in the path or alternative path between the CENIC edge router and where the Amino STB will be located. In short, you will be enabling your routers to pass multicast, and pointing them to the Rendezvous Point where the multicast traffic can be found, and enabling each interface to pass multicast, as required.

Make sure you have your Enable and ConfigT passwords.

conf t
! enable multicast globally
 ip multicast-routing
! RP address defined by
 ip pim rp-address 137.164.16.1
# Rendezvous Point on CENIC network

! Per Interface enable PIM-SM
 interface <num>
  ip pim sparse-mode
# repeat for each interface required

Don’t forget to write term to test it, and/or write all or write to save it permanently.

Other Multicast feeds-
If your network is already configured for multicast and you are already passing multicast traffic within your LAN, or plan on it in the future, then you more than likely already have a Rendezvous Point configured, or will need to do so. In this case, you will need to configure MDSP Peer back to their edge router. This will need to be coordinated with CENIC.

config t
! Enable MSDP peering. recommended to use a loopback address within your IP range ip msdp peer <cenic provided IP> connect-source Loopback0

You will need to repeat the following steps for every router within the network that is in the path or alternative path between the CENIC edge router and where the Amino STB will be located. In short, you will be enabling your routers to pass multicast, and pointing them to your Rendezvous Point, and enabling each interface to pass multicast, as required.

Make sure you have your Enable and ConfigT passwords.

conf t
! enable multicast globally
 ip multicast-routing
! RP address defined by
 ip pim rp-address <your RP>
# Rendezvous Point on your network
! Per Interface enable PIM-SM
 interface <num>
  ip pim sparse-mode
# repeat for each interface required

Don’t forget to write term to test it, and/or write all or write to save it permanently.
