Commit c17f259d ("router-advert: T3561: add support for specific routes") used
tabs over spaces in the Migration script which triggered a TabError (inconsistent
use of tabs and spaces in indentation").

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".
|
|
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.
|
|
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.

nptv6: T2518: Support IPv6 address translation
|
|
|
|
|
|
|
|
Rename CLI options local-ip to source-address and remote-ip to remote to
get a consistent CLI experience for the user.
|
|
Streamline the CLI configuration where we try to use remote on other interfaces
like vxlan, geneve.
|
|
Streamline the CLI configuration where we try to use source-address when
creating connections which are especially sourced from a discrete address.
|

The following list shows the mapping of VyOS tunnel encapsulation modes to the
corresponding Linux modes.
VyOS Linux
gre gre
gre-bridge gretap
ipip ipip
ipip6 ipip6
ip6ip6 ip6ip6
ip6gre ip6gre
sit sit
Besides gre-bridge this is pretty consistent. As bridge interfaces are also
called tap interfaces gre-bridge will be renamed to gretap to make the
post-processing much easier.
This means (in detail) that there are no more child classes of _Tunnel and
there will be now one geneirc TunnelIf class handling all sorts of encapsulation.

When moving from Quagga to FRR the BGP address-family was extended by an
invalid peer-group statement. FRR always moved a configured peer-group
from the AFI level down to the neighbor level.
With the migration to FRR reload we must take care about this by ourselves.

Commit 0f8beae7426 ("system: T2486: migrate disable-dhcp-nameservers to
name-servers-dhcp") added a migration script for moving the name-servers.
A small glitch was introduced when referencing vif-c interfaces unter a vif-s
interface where a variable got referenced which was not defined.

|
If the RPKI cache name equals the configured address, renaming is not possible,
as rename expects the new path to not exist.

When per interface OSPF configuration is migrated into "protocols ospf interface"
we should cleanup and empty ip {} node unter the individual interface. This
makes the config look more nicely.

interface"
For easier maintenance and operability move the interface specific protocol
setting of OSPF to the OSPF protocol section. This is now also in-line with IS-IS.
This means to migrate:
ethernet eth0 {
vif 202 {
ip {
ospf {
authentication {
md5 {
key-id 10 {
md5-key vyosvyos
}
}
}
dead-interval 40
hello-interval 10
priority 1
retransmit-interval 5
transmit-delay 1
}
}
}
}
to
protocols {
ospf {
interface eth0.201 {
authentication {
md5 {
key-id 10 {
md5-key vyosvyos
}
}
}
dead-interval 40
hello-interval 10
priority 1
retransmit-interval 5
transmit-delay 1
}
}

This commit provides the implementation of the OSPF CLI with a Jinja2 template
that is loaded by FRR reload.

IPv6 enable can be considered once the ipv6 node is present!

When VyOS boots the first time with the default configuration there it actually
no "interface ethernet" node present in the config, thus we must exit the
migrator.
Without this change vyos.configtree.ConfigTreeError: Path [b'interfaces ethernet']
doesn't exist will be thrown.

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

After migrating the ethernet interfaces from the good old Perl days the
smp-affinity node yet has no effect anymore as the code is still missing (my
bad, sorry).
Drop the smp-affinity node and rather use tuned instead with the
network-throughput or network-latency profile.
- network-throughput: Profile for throughput network tuning. It is based on the
throughput-performance profile. It additionaly increases kernel network buffers.
- network-latency: Profile for low latency network tuning. It is based on the
latency-performance profile. It additionaly disables transparent hugepages,
NUMA balancing and tunes several other network related sysctl parameters.
I'd set network-throughput as the default on a new set system option performance
<throughput | latency> CLI node which is present in the default configuration.
