global features
So this is a big update.
The first thing that was done was a refactor to the FRR LDP template, MPLS handler, and XML conf tree MPLS global additions.
The refactors should work and I did test them in my lab. It seems that everything does work as needed so far in my testing.
There is something here that is considered configuration breaking from the old setup though. In the old setup the MPLS interface operation (as in the interfaces accepting MPLS labels and processing them) was tied with LDP. What this means is that MPLS processing was enabled at the same time as LDP interfaces were configured. We do not want this behavior for the future as there's other MPLS underlay technologies like SR and RSVP. If someone wants to enable SR or RSVP without enabling LDP then they now can. Before, they couldn't. The other additions are global changes to MPLS TTL propagation and MPLS max TTL enforcement. They have now been added.
Lastly, there is an frr-reload bug that Runar Borge found with this. We have found that when totally deleting LDP that there has to be 3 commits done. This is because frr-reload doesn't properly do what it needs to do in 1 operation so we had to do 3. This will only affect people that are doing an entire LDP clear using "delete protocols mpls ldp." Otherwise it isn't seen.
Anyway, this refactor now works with the FRR daemon directly for all changes. This also makes it much easier for adding stuff in the future.
Thank you

By design a CLI node should not be named by its plural but rather describe it
as singular.

link-local addresses can still be disabled using:

This reverts commit 806f35b5856c3f8dae634718a6a9e82cc90bb63a.
Unfortunately this did not work our in the attempt to bridge a station to a
bridge "brX" interface. Also adjusting the wireless interface during operation
cause several exceptions and the feature is removed again as it was never in any
production system.

Python value
We should not use hardcoded Python values whenever possible. vyos.xml provides
an abstraction of the XML CLI definitions providing default values from the CLI
specified via the <defaultValue> node.
This increases consistency among all XML/Python wrappers.
Additional small fixes in this commit (besides the bad practice incorporating
unrelated changes into the same commit) contain:
- Keyboard layout shout be explicitly set for /dev/console
- Added missing Debian dependency on console-data
- When looking for a key in a dict, we do not need to specify dict.keys()

1. Due to the previous focus on the implementation of VLAN filter, it was not considered to include MTU settings, which will lead to MTU setting errors in some cases
2. In order to make VLAN aware of the work of the bridge, it is necessary to specify the allowed VLAN ID range for the bridge itself, and forget to join it before

This commit has to do with the addition of miscellaneous MPLS parameters, as well as miscellaneous LDP parameters. Per c-po, for miscellaneous options and whatnot that do not fit anywhere we will put them into a specific "parameters" node.
I also did some global linux configuration changes here. We make changes to kernel options "net.mpls.ip_ttl_propagate" and "net.mpls.default_ttl" which should allow the behavior of VyOS to have the same as routers from the big vendors.
I added two LDP options for cisco interoperation TLV and for a dual stack preference.
Lastly, I went through and changes some of the help/description fields in the definitions page because I just felt they weren't uniform and the words seemed to not properly explain what they were doing. I also did some code clean up (or tried to...) with comments and whatnot.

The commit has to do with the addition of targeted LDP neighbors and parameters being added. FRR allows for this functionality and I just wanted to add it.
We have basically 4 options that are added. Enabling targeted LDP functionality, the targeted neighbor, the hello interval of targeted sessions, and the hold time of targeted sessions. Both IPv4 and IPv6 has been coded in.
|
|
Some might want to have an IP address handed out by a DHCP server but not want
a default route to be installed. This can be done using the CLI command:
"set interfaces ethernet eth2 dhcp-options no-default-route"
|
|
|
|
|
|
|
|
This reduces duplicated #include statements as each interface type already
contained the individual includes.
|
|
Add new CLI command "set system options performance <latency | throughput>"
|
|
The commit has to do with the addition of session hold time parameter for LDP neighbors. This allows for being able to change said hold time on a static neighbor.
The way that this works is to have it either delegated to a value (15-65535), or to just be default to whatever FRR stipulates or per the other session configuration values.
I opted to remove the "-ipv4-" only because we know it's an IPv4 session that one has to create first. I figure it's redundant to add it there so I removed it.

The commit has to do with the addition of TTL security for LDP neighbors. The code was 90% done by Viascheslav. I modified it a little bit to get it to properly work.
We added more parameters to the neighbors dynamic loop. Once this is merged then we should be able to add more for the dynamic neighbor statements.
The way that this works is to have either TTL disabled, or to add the amount of hops accepted for the neighbor.

Now as we can dynamically create bridge interfaces we can also reset the interface

The commit has to do with separating the hello/hold timers from being only IPv4 to being both IPv4 and IPv6.
I renamed the existing hello and hold timers with an "-ipv4" and added ones that were "-ipv6". I did verify that the commands properly commit under FRR as well. I also added some room on the protocols_mpls.py file for the different variables as it seems we're might end up having longer names. Removed some spaces that I found too that weren't needed on ldpd.frr.tmpl as well.

Error while copying statement from preference node.

The current implementation for bridge based interfaces has an issue which is
caused by priority inheritance. We always assumed that the bridge interface will
be created last, but this may not be true in all cases, where some interfaces
will be created "on demand" - e.g. OpenVPN or late (VXLAN, GENEVE).
As we already have a bunch of verify steps in place we should not see a bridge
interface leak to the underlaying infrastructure code. This means, whenever an
interface will be member of a bridge, and the bridge does yet not exist, we will
create it in advance in the interface context, as the bridge code will be run
in the same commit but maybe sooner or later.
This will also be the solution for T2924.
