quagga-ospf6d: doesn't get routes from other routers

[suedwestlicht]

Maintainer: acinonyx

Environment:
LEDE Reboot 17.01.1 r3316-7eb58cf109 / LuCI lede-17.01 branch (git-17.100.70571-29fabe2)
TP-Link TL-WR1043N/ND v4

Description:
ospfd of quagga works ok.

ospf6d of quagga recognizes its neighbours but doesn't get routes.
Package: quagga-ospf6d
Version: 1.1.0-1

It seems we have a bad quagga version.
Please see https://lists.gt.net/quagga/users/32153

Would it be possible to package an older version of quagga?

[lucize]

can you try this #319 ?

[suedwestlicht]

How can I install the new version? I have no cross compilation environment set up.

[lucize]

git pull origin pull/319/head in git root of routing master tree
and after that make a symlink of frr into package/feeds/routing/
make menuconfig and you should find it in the routing submenu

[lucize]

you need to setup a SDK hint
clone the git, resolve dependencies based on your distro then

./scripts/feeds update -a
./scripts/feeds install -a
clone the PR, make the symlink
make menuconfig
select frr packages

[suedwestlicht]

git clone https://git.lede-project.org/source.git
cd source
./scripts/feeds update -a
./scripts/feeds install -a

*** all went ok ***

Now I am stuck. In which dir shall I clone what?

[lucize]

cd feeds/routing
git pull origin pull/319/head
ln -s ../../../feeds/routing/frr/ ../../package/feeds/routing/
cd ../..
make menuconfig

[suedwestlicht]

ok. symlink looks good (resolves)
make menuconfig (shows the correct architecture Atheros AR7xxx/AR9xxx)

now I am too stupid to finde the frr packages. How can I activate them? I guess I have to build quagga's ospf6d only?

do I have to check
[ ] Build the LEDE SDK
[ ] Package the LEDE-based Toolchain
?

[lucize]

you're not stupid :) !
on subtarget find your router model and version, confirm on the router box that you have the V4 and select the V4 from subtarget
after that go to Network -> Routing and Redirection -> frr (select it with space to be like * not M and select frr packages that you need
exit and save
make V=s -j4
-j sets the number of threads, so set it to the number of your system cpu V=s is verbose

[lucize]

don't forget to select LuCI otherwise you'll not have web interface in the image

[suedwestlicht]

Oh, I thought I could build the packages for quagga only, not a whole Image.

[lucize]

make package/frr/compile V=s -j4
but then you must have the git version of your installed image
git checkout <shanumber> of your installed release

[lucize]

it needs libjson-c as a dep, you will find them in bin folder and if you're lucky if the libs haven't change much from your version maybe it will run without checking out the older release

[suedwestlicht]

It does. I had to build an image first to get some lib stuff. I could build the frr packages.

I use vytsh, zebra, ospfd and ospf6d

frr's zebra, ospfd and ospf6d seem to work fine. Thanks a lot.

vtysh isnt usable out of the box because it doesn't find "more"

root@ap-gz:~# vtysh
Hello, this is FRRouting (version 3.0-rc1).
Copyright 1996-2005 Kunihiro Ishiguro, et al.

sh: more: not found
ap-gz# show ipv6 ospf6 route 
sh: more: not found

So I have to set
export VTYSH_PAGER=less

Then all is fine.

[lucize]

yes, I saw the more error, but it's still in rc and never been tested on LEDE, hopefully will be fixed
glad it worked out

[suedwestlicht]

What's next? Will frr replace quagga or will quagga get updated in openwrt or lede?

[lucize]

the master frr version has more daemons implementations like EIGRP, EVPN so frr seems to be the future, that's why it forked, the packages could coexist, but quagga development seems to be slow
the master version has some issues with cross compile see FRRouting/frr#958

tried changing to less but I don't like how it prints on screen if there are few lines to show, more can be manually added to busybox in the advanced options of busybox

anyway, old version uses cat so I replace it with cat
