Different protocols, different dynamics.

P.S. Those are not XORP-related questions, so I won't go into
details on the subject. Check some books that describe those
protocols for better understanding of the issues.

Subject: [Xorp-hackers] Supporting PIM-DM
Message-ID: <32a44f580711050118w5a601400p8920cb4d924f342f@mail.gmail.com>

Dear Xorp Hackers,

I am interesting in PIM-DM support.
I was trying to search the site for information if this item is on the
roadmap or not,
but I couldn't find it.

Is there a plan to support PIM-DM, and if so, when is it planned to?

Thank you very much,
Raz.

It is on our internal TODO list.
So far we haven't decided when we will start the implementation.

That's all C++ syntax.

FinderConstants::FINDER_DEFAULT_HOST() is a method inside class
FinderConstants (see libxipc/finder_constants.hh).
It returns IPv4 address (see libxorp/ipv4.hh).
The str() method for the IPv4 address class returns a C++ string.
That string itself is assigned to variable "finder_hostname".

Hope that helps,
Pavlin

Excellent!  Thanks for fixing this.

I need to rebuild my test system for this scenario, but hopefully can
confirm that it does indeed fix my problem in a few days.

What do you mean by "hardware access calls"? The kernel system
calls?

We don't have a compiled list of all system calls used by XORP
because there is no much use for it.
If you need to consider at the routing-related system calls, check
the bottom layer of the FEA which interacts directly with the
kernel. However, this won't help you understand the rest of XORP.

You need to read first the XORP design documents to get the
high-level picture and only then you should go into the details of
the source code.

Pavlin

Those are called by xorpsh.
The xorpsh template files (etc/templates/*.cmds) specify the names
of the binaries.
Xorpsh itself uses the RunCommand class (libxorp/run_command.hh) to
execute them.

configure.in file .
And also what is performed by configure shell script and how it is related 2 above files.

All this is part of the wonderful and magical world of autotools
(autoconf/automake/libtool). Those are described in the info pages
online and in the following online book:
