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.

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.
|
|
For L2TPv3 to properly work there must be a routing entry present for the
remote side of the tunnel, or use a directly connected subnet.

RFC7348 recommends VXLAN tunnels preserve a 1500 byte MTU.

When loading a configuration for BGP that contains the graceful-restart
options, the frr-reload script will not return 0, but the config is accepted.
This is a false positive, and related to https://github.com/FRRouting/frr/issues/8403

|
When validating FRR profiles, only load the configuration for each individual
profile instead of all profiles. This is done by a new argument to getFRRconfig()
named endsection='^!' which tells what is the delimiter when a config section
of FRR ends, this is usually "^!", but for BFD profiles this is "^ !", as this
is a new level under the FRR CLI.

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

After upgrading FRR to a newer revision in stable/7.5 branch we can drop the
workaround where an additional whitespace was required after the "router
isis FOOO " statement.

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".

Instead of multiple if/else paths, use a common vrf string variable which is
either populated or not. In addtion when interfaces are configured for a given
VRF, harden the regex for config reload.
|
|
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

Within this example a MGMT VRF is used to administer the system, thus also move
the NTP portion into that VRF.

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.

When we leak routes to a VRF it is verified that the target VRF actually
exists.

Currently every smoketest does the setup and destruction of the configsession
on its own durin setUp(). This creates a lot of overhead and one configsession
should be re-used during execution of every smoketest script.
In addiion a test that failed will leaf the system in an unconsistent state.
For this reason before the test is executed we will save the running config
to /tmp and the will re-load the config after the test has passed, always
ensuring a clean environment for the next test.

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.

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

Commit 52ee92b8 ("pppoe: T3386: Fix client ip-pool stop range") fixed the
generated client range configuration line for Accel-PPP but missed out altering
the testcase, too which validates the generated configuration line.

* 'T3379' of https://github.com/sever-sever/vyos-1x:

Support setting additional options to the GENEVE tunnel like:
- ttl
- tos
- do not fragment bit
- ipv6 flowlabel
|
|
Verify proper configuration of VXLAN parameters for
- source-interface
- source-address
- remote
- vni
- group
Before it was only verified if the VXLAN tunnel interface was configured
at all but not if the parameters are correct, too.

Commit 49bc3f1e ("vif: T3349: use fixed ordering when enabling parent and child
interface") also shipped a smoketest to verify the functionality of the parent
admin up/down problematic from T3349. The generic testcase failed for the VLAN
aware bridge as vlan-awarenes was not turned on.
|
|
When a VIF/VLAN interface is placed in admin down state but the lower
interface, serving the vlan, is moved from admin down -> admin up, all its
vlan interfaces will be placed in admin up state, too.
This is bad as a VLAN interface will become admin up even if its specified as
admin down after a reboot.
To reproduce:
set interfaces ethernet eth1 vif 20 disable
set interfaces ethernet eth1 disable
commit
delete interfaces ethernet eth1 disable
commit
Now check the interface state and it returns UP,LOWER_UP
7: eth1.20@eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000

There had been four implementations of "ip -d -j link show interface" scattered
accross the codebase. Those implementations have now been combined into a new
helper:
vyos.util.get_json_iface_options()
|
|
|
|
Rename CLI options local-ip to source-address and remote-ip to remote to
get a consistent CLI experience for the user.
