The BGP conditional advertisement feature uses the non-exist-map or the
exist-map and the advertise-map keywords of the neighbor advertise-map command
in order to track routes by the route prefix.
non-exist-map
=============
* If a route prefix is not present in the output of non-exist-map command, then
advertise the route specified by the advertise-map command.
* If a route prefix is present in the output of non-exist-map command, then do
not advertise the route specified by the addvertise-map command.
exist-map
=========
* If a route prefix is present in the output of exist-map command, then
advertise the route specified by the advertise-map command.
* If a route prefix is not present in the output of exist-map command, then do
not advertise the route specified by the advertise-map command.
This feature is useful when some prefixes are advertised to one of its peers
only if the information from the other peer is not present (due to failure in
peering session or partial reachability etc).
The conditional BGP announcements are sent in addition to the normal
announcements that a BGP router sends to its peer.
CLI nodes can be found under:
* set protocols bgp neighbor <ip> address-family <afi> conditional-advertisement
* set protocols bgp peer-group <p> address-family <afi> conditional-advertisement

This command is applicable at the global level and at an individual bgp level.
If applied at the global level all bgp instances will wait for fib installation
before announcing routes and there is no way to turn it off for a particular
BGP vrf.
|
|
Administrative shutdown of all peers of a bgp instance. Drop all BGP peers,
but preserve their configurations. The peers are notified in accordance with
RFC 8203 by sending a NOTIFICATION message with error code Cease and subcode
Administrative Shutdown prior to terminating connections.
This global shutdown is independent of the neighbor shutdown, meaning that
individually shut down peers will not be affected by lifting it.
|
|
This command enables rejection of incoming and outgoing routes having AS_SET
or AS_CONFED_SET type.
|
|
This command allows user to prevent session establishment with BGP peers with
lower holdtime less than configured minimum holdtime.
When this command is not set, minimum holdtime does not work.
|
|
Whenever BGP peer address becomes unreachable we must bring down the BGP
session immediately. Currently only single-hop EBGP sessions are brought down
immediately. IBGP and multi-hop EBGP sessions wait for hold-timer expiry to
bring down the sessions.
This new configuration option helps user to teardown BGP sessions immediately
whenever peer becomes unreachable.
This configuration is available at the bgp level. When enabled, configuration
is applied to all the neighbors configured in that bgp instance.

Set the period to rerun the conditional advertisement scanner process.
The default is 60 seconds.

netns: T3829: Ability to configure network namespaces

Mark session as passive: a passive session will not attempt to start the
connection and will wait for control packets from peer before it begins
replying.
This feature is useful when you have a router that acts as the central node of
a star network and you want to avoid sending BFD control packets you don't
need to. The default is active-mode

To allow IPv6 only for vpn sstp sessions we have to add
'ppp-options' which can disable IPv4 allocation explicity.
Additional IPv6 ppp-options and fix template for it.

This extends commit 6f87d8c910 ("ospf: T3757: support to configure area at an
interface level") with a completion helper to show which Area ID is already in
use when configuring the area for an interface.

There is no benefit in the BGP specific definition of a "description" node.
|
|
This is used for both VRRP groups and sync-groups.

Commit a8b2e52148d ("xml: Update routing-passive-interface-xml.i file extension

the OSPF include.

DHCP servers "shared-network" level only makes sense if one can specify
configuration items that can be inherited by individual subnets. This is now
possible for name-servers and the domain-name.
set service dhcp-server shared-network-name LAN domain-name 'vyos.net'
set service dhcp-server shared-network-name LAN name-server '192.0.2.1'
|
|
IPv4 DHCP uses "dns-server" to specify one or more name-servers for a given
pool. In order to use the same CLI syntax this should be renamed to name-server,
which is already the case for DHCPv6.
