FRR opensource routing to CME MDP

 In this blog we will look at a simple  but effective means for deploying multicast router over frr to the CME multicast data platform

https://www.cmegroup.com/confluence/display/EPICSANDBOX/CME+Market+Data+Platform+Connectivity#CMEMarketDataPlatformConnectivity-Figure:GRETunnelwithinIPSecTunnel

note: You typically will get a ipv4 address that will be used for the pim-RP

Traffic for pim-joins and multicast will be delivered via the gre interface ( gre1 in my example )

You will need to install snapd & frr and have your gre1 interface defined b4 starting .

  sudo yum install snapd

  yum install -y https://github.com/FRRouting/frr/releases/download/frr-5.0.1/frr-5.0.1-2018070501.el7.centos.x86_64.rpm

   

  sudo snap install frr

   

 sudo systemctl enable --now snapd.socket

sample frr.conf

[kfelix@mcastrt1 ~]#  /var/lib/snapd/snap/bin/frr.vtysh -c "show running"

The dummy255 interface was crafted for testing and before enable igmp for the LAN interface.
