Quite a few well-known communities from IANA's list do
not receive special treatment in Cisco IOS XR, and at least one
community on Cisco IOS XR's special treatment list, internet == 0:0,
is not formally a well-known community as it is not in [IANA-WKC] (it
is taken from the Reserved range [0x00000000-0x0000FFFF]).

This is Cisco-specific command which is causing lots of questions when it
comes to debugging and/or configuring it properly, but overall, this behavior
is very odd and it's not clear how it should be treated between different
vendor implementations.
Let's deprecate it and let the operators use 0:0/0 communities as they want.

Add a keyword self-originate" to extend current CLI commands to filter out self-originated routes only
a\) CLI to show ipv4/ipv6 self-originated routes
"show [ip] bgp [afi] [safi] [all] self-originate [wide|json]"
b\) CLI to show evpn self-originated routes
"show bgp l2vpn evpn route [detail] [type <ead|macip|multicast|es|prefix|1|2|3|4|5>] self-originate [json]"

A new keyword permits changing the BGP as-notation output:
- [no] router bgp <> [vrf BLABLA] [as-notation [<dot|plain|dot+>]]
At the BGP instance creation, the output will inherit the way the
BGP instance is declared. For instance, the 'router bgp 1.1'
command will configure the output in the dot format. However, if
the client wants to choose an alternate output, he will have to
add the extra command: 'router bgp 1.1 as-notation dot+'.
Also, if the user wants to have plain format, even if the BGP
instance is declared in dot format, the keyword can also be used
for that.
The as-notation output is only taken into account at the BGP
instance creation. In the case where VPN instances are used,
a separate instance may be dynamically created. In that case,
the real as-notation format will be taken into acccount at the
first configuration.
Linking the as-notation format with the BGP instance makes sense,
as the operators want to keep consistency of what they configure.
One technical reason why to link the as-notation output with the
BGP instance creation is that the as-path segment lists stored
in the BGP updates use a string representation to handle aspath
operations (by using regexp for instance). Changing on the fly
the output needs to regenerate this string representation to the
correct format. Linking the configuration to the BGP instance
creation avoids refreshing the BGP updates. A similar mechanism
is put in place in junos too.

Consider this scenario:
Lots of peers with a bunch of route information that is changing
fast. One of the peers happens to be really slow for whatever
reason. The way the output queue is filled is that bgpd puts
64 packets at a time and then reschedules itself to send more
in the future. Now suppose that peer has hit it's input Queue
limit and is slow. As such bgp will continue to add data to
the output Queue, irrelevant if the other side is receiving
this data.
Let's limit the Output Queue to the same limit as the Input
Queue. This should prevent bgp eating up large amounts of
memory as stream data when under severe network trauma.
