set vrf name red protocols bgp address-family l2vpn-evpn advertise ipv4 unicast

After commit 73557d68 ("bgp: T1711: remove ASN tagNode and move to 'local-as'")
when the BGP tag node was removed there is no need anymore for a script based
completion helper, we can rather rely on the build in "path" variant.

This was not possible due to a regression in iproute2 where the erspan_dir key
did not have a value. See [1] for more information.

Port over the regex used in the old node.def code-base and make this limitation
also live on the new CLI interface.

Commit 548d9057e3e (vrf: T3344: move dynamic routing protocols under "vrf name
<name> protocols") temporary removed the possibility to specify the VNI for a
given VRF to to changing of the CLI configuration nodes.
As VNI is set inside zebra, we can re-use the now widely deployed frr python
library to configure and change the configuration without any interference to
other FRR daemons.

Instead of having a dedicated ERSPAN interface type, rather move the specifics
into "interface tunnel". A migrator is not needed as there is yet no LTS release
with this feature and this is considered experimental.

Sometimes a modem might give a local IP before it retrieves a WAN IP.
This can be an issue with failover routes,
since the default route will get overridden.

Commit 5b22ebae ("T3170: check if any generated node.def files are empty") added
an initial test to find empty node.def files created by build-command-templates
or build-command-op-templates.
The problem was that GNU find always returns 0, thus the condition to bail out
on error was always met. This has been corrected to return false on hits only.

... this has been migrated to vyos-1x.

This reverts commit d8c27642a3753513ae1d3c433fa46858a5ee946c.

Currently if there are XML nodes defined in multiple places it can and will
happen that one overrides the other. In this case, the "protocols static arp"
definition file overwrites the node.def file in the "protocols static" folder
that had a priority - the priority is essential for l2tpv3 to work.

conf-mode: Add Dvorak layout

Every time when set configuration bgp, you need set AS number. There is very
less benefit in this system so the AS number is moved from a tagNode level down
to a leafNode with the name "local-as", same as on the neighbor or peer-group
level.
This changes the CLI configuration from:
set protocols bgp 100 neighbor 10.10.1.2 remote-as 200
to
set protocols bgp local-as 100
set protocols bgp neighbor 10.10.1.2 remote-as 200

As we and FRR do not support multiple FRR process instances, there is no need
to make this configurable for a user. We rather rely on a solid default "VyOS".
|
|
VRF support can be tested using:
set vrf name red table 1000
set vrf name red protocols isis domain FOOO
set vrf name red protocols isis net 49.0001.1921.6800.1002.00
set vrf name red protocols isis interface eth1
|
|
As there can only be one running IS-IS process (FRR limitation) there is no need
in having a tagNode here. This adds artifical restrictions/limitations when
moving on to support VRFs for IS-IS protocol.

Private VLAN, also known as port isolation, is a technique in computer
networking where a VLAN contains switch ports that are restricted such that
they can only communicate with a given "uplink". The restricted ports are
called "private ports".
Each private VLAN typically contains many private ports, and a single uplink.
The uplink will typically be a port (or link aggregation group) connected to a
router, firewall, server, provider network, or similar central resource.

VyOS 1.2 (crux) rejected prefixes other then of site /64.
[ interfaces ethernet eth0 ipv6 address eui64 2006:ab00:abe1::2/127 ]
Error: Prefix lenght is 127. It must be 64.
Same should be done on VyOS 1.3 and newer

As the amount of include files now has reached a certain amount, it is getting
more and more crowsded, thuse introducing "per topic" subdirectories on the
filesystem to keep a clean structure makes sense.

conf-mode: T2425: Add XML for policy-lists
|
|
We must ensure that an interface is already added to a VRF before it is
referenced inside a VRF context, e.g. OSPF.
|
|
Instead of having the dynamic routing protocols OSPF and BGP residing under
the "protocols vrf <name> [ospf|bgp]" nodes, rather move them directly under
the "vrf name <name> protocols [ospf|bgp]" node. Now all VRF related parts
are placed under the same root node.
This eases the verify steps tremendously, as we do not need to check wheter a
VRF eists or not, it will always exist as we operate under a child node.

When including XML files they all contained a comment from where the snipped
had actually been included from. The comment had been "included start" and
"included end" instead of "include start" and "include end".
This commit corrects the glitch.

The following VyOS CLI config
vrf red {
bgp 100 {
neighbor 1.1.1.1 {
peer-group foo
}
peer-group foo {
passive
password bar
remote-as 200
}
}
}
Will generaste the FRR configuration:
!
router bgp 100 vrf red
no bgp ebgp-requires-policy
no bgp network import-check
neighbor foo peer-group
neighbor foo remote-as 200
neighbor foo password bar
neighbor foo passive
neighbor 1.1.1.1 peer-group foo
!

As the amount of include files now has reached a certain amount, this also
introduces "per topic" subdirectories on the filesystem to keep a clean
structure.
This commit is related to the change in the OSPF structure done in 952c52ef01
("vrf: ospf: T2271: re-arrange xml include building blocks").

VyOS CLI config:
vrf red {
ospf {
default-information {
originate {
always
}
}
default-metric 30
passive-interface default
}
}
Will create the FRR configuration snippet:
!
router ospf vrf red
auto-cost reference-bandwidth 100
timers throttle spf 200 1000 10000
passive-interface default
default-metric 30
default-information originate always
!

In order to fully re-use the XML based OSPF CLI definition for per-VRF routing,
the file structure needs to be reorganized and the common OSPF definition is
moved to its dedicated ospf-common-config.xml.i file, which can then be fully
re-included at the VRF level.
As the amount of include files now has reached a certain amount, this also
introduces "per topic" subdirectories on the filesystem to keep a clean
structure.

set protocols bgp 65010 address-family l2vpn-evpn vni 100 route-target both 516:10516
set protocols bgp 65010 address-family l2vpn-evpn vni 100 rd 192.168.0.1:514
Todo: add verify() step to check if at least one evpn enabled BGP neighbor
exits, else FRR will error out with: This command is only supported under EVPN VRF
