I’ve been working on doing some multicast labs lately and am constantly resetting my lab devices to their default configs and starting from scratch. As many of us know, to enable PIM on all of your interfaces you must go into each interface and enable it manually. There is no default command to enable PIM on all interfaces. We know PIM should be enabled 1 to 1 with interfaces involved in routing making this a boon. With that in mind, and the fact that I am rather comfortable with the concept of needing PIM on the interfaces, and likely speak and type this command in my sleep, I decided to make it easier and modify a previous TCL script I had written to enable PIM on every interface that has an IP address assigned to it. With the great “Send to Chat” feature of SecureCRT I can do this across my entire topology on one fell swoop. In a real world environment, you could use a tool like Solarwinds to push this out to your devices.
