EIGRP is free software that implements RFC 7868 (https://www.rfc-editor.org/info/rfc7868). This is a clone of, and rewrite of, the code found int the FRR (https://github.com/FRRouting/frr). While EIGRP is designed be protocol agnostic, it currently only handles IPv4.
First and foremost, I agree with evolution (small commits) vs revolution (large commits). That said, significant changes are needed to refactor the code to address issues, scale, and missing capabilities within the code. This should not be considered as disrespecting the original authors or editors, in fact i have complete respect and admiration for them.
To that point, and due due to the initial effort needed for the wide-metric work, I have cloned EIGRP from FRR and created an independent repo that i can perform small commits to. Each of the commits i perform have minimal to now testing and a high chance of destabilizing EIGRP code base. My intent is to wrap up the refactor work along with the wide metrics and bases to support IPv6. Then deliver a finished, commercial ready, version of the EIGRP code. To ease the adoption, I have gone to lengths to ensure what's being done is a drop in overlay to FRR.
I completely understand the repo-owners aversion to large code drops, but I just don't see a clean way to deliver stable code which is not also a large change set.
As for code refactoring. My goals are as follows.
- make it readable!!!! use function scoping, and CRUD model
- Add wide metrics in - this involves major edits to metrics, neighbors, and interface code
- make it modular (use typedef to hide data, create functions that align with data objects)
- Add redistribution
- Add Query Filtering (support stub like capability without doing 'STUBS')
- Add IPv6 support
- Anything else that sounds like fun
This is not a standalone repo. To contribute to the development of this code, setup you development environment per the FRR documentation:
http://docs.frrouting.org/projects/dev-guide/en/latest/building.html
Next, download EIGRP source
git clone https://github.com/diivious/eigrpd.git eigrpd
Once setup, checkout the FRR source
git clone https://github.com/frrouting/frr.git FRR
Delete the existing eigrpd directory
cd frr
rm -rf eigrpd
Copy this version of EIGRP top FRR
cp -R ../eigrpd .
Lastly, build FRR as normal
./bootstrap.sh
./configure \
--enable-exampledir=/usr/share/doc/frr/examples/ \
--localstatedir=/var/opt/frr \
--sbindir=/usr/lib/frr \
--sysconfdir=/etc/frr \
--enable-multipath=64 \
--enable-user=frr \
--enable-group=frr \
--enable-vty-group=frrvty \
--enable-configfile-mask=0640 \
--enable-logfile-mask=0640 \
--enable-fpm \
--with-pkg-git-version \
--with-pkg-extra-version=-dVs-EIGRP-v0
make
