The XORP User Manual (under the Documentation section on the XORP
Web page) should have sufficient information regarding the XORP
configuration.
There is also the "Getting Started" Web page which is a very
abbreviated version of the User Manual. Those should tell you how to
configure a number of interfaces or a number of addresses per
interface (among other things).

Finally, the xorp/rtrmgr/config.boot.sample (also linked from the
Getting Started Web page) is a sample configuration which obviously
MUST be edited before trying it.

Hope that helps,
Pavlin

Message-ID: <F177A9E87D8A70459F6991D3B171CF0F75B9B1@ex01.cursor.as>

Hi,

 

I am planning to do some changes to the XORP OSPF module.

I am looking for some high level design documentation similar to the
PDFs that are available from: http://xorp.org/design_docs.html. 

(not the autogenerated kdoc)

 

Regards,

Erlend Knutsen

Hello,

 

I need to know how can I make multipath (load balancing) with RIP protocolo
routing. 

Do you know how I can do it?

 

I know that with OSPF it's posible, but what is the code that uses XORP to
do it?

 

Thank you very much.

In RIP the router needs to keep track of all distance vectors to a
particular destination rather than choosing only the best one.

FYI, XORP currently doesn't implement multipath for any of the
routing protocols:

Subject: [Xorp-hackers] multicast source filter API in linux
Message-ID: <fcfc34be0705311154v3296c874if20b7d020b66d569@mail.gmail.com>

When I set the source filter using the setsockopt() call for the
following scenario
mode: INCLUDE
number of sources: 3
sources: s1, s2, s3
Group: G

The kernel first sends out a TO_EX{} report for G and then a TO_IN{s1,
s2, s3} report for G.

Does anybody know why linux does this?

Thanks,
Sachin

Message-ID: <4769af410705311307y68d0adf8td70591222d6a3487@mail.gmail.com>

hi

Does anyone know what the support for loading shared libraries is under :

windows
openbsd
dragonfly bsd
mac os

I have access to linux and freebsd systems.

Copies of the manual pages or pointers to urls would be great as I am
playing with with dynamically loading parts of the forwarding engine
abstraction.

Many thanks

Adam

The only reason that comes to mind is if in your code you actually
join first the group G (for any source), and then you modify the
source filter to INCLUDE mode.
I just tried it with Linux kernel 2.6.20 and TO_EX{} IGMPv3 report
is sent when you use the traditional mechanism for joining (*,G).

If this is not the case, then hopefully the folks on this list who
are familiar with the host-side kernel IGMPv3 implementations can
provide a better explanation.
