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.

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.
|
|
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

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
|
|
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").
|
|
|
|
|
|
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

VyOS 1.2 had a default ttl of 16 hardcoded to the node.def file [1], so until
this is handled via a migration script we have to obey that particular
setting.

dhcp: T3300: add DHCP default route distance
|
|
|
|
|
|
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.
|
|
A VXLAN tunnel may now get a TTL, TOS, Flowlabel option specified. It is also
possible to disable learning of unknown addresses into the forwarding database.
|
|
|
|
As thought in the beginning the dhcp-interface route option can not be
superseeded by the interface option. When a route is installed for a DHCP
interface, that interface is usually a broadcast interface which can not be
used for plain interface-based routes.
The old Vyatta logic was migrated to Python where the current received
next-hop address from the DHCP interface is installed as next-hop address.
|
|
VXLAN will get tos, ttl and flowlabel options thus make individual parameter
settings reusable by splitting tunnel-parameters-ip.xml.i into individual files.

bfd: T3310: migrate to get_config_dict() and FRR reload
|
|
|
|
|
|
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.
