Behavior change for BGP-independent AS domains—Independent domains use the
transitive path attribute 128 (attribute set) messages to tunnel the independent
domain's BGP attributes through the internal BGP (IBGP) core. In Junos OS Release
10.3 and later, if you have not configured an independent domain in any routing instance,
BGP treats the received attribute 128 message as an unknown attribute. The AS path
field in the command has been updated to display an unrecognized attribute
show route
and associated hexadecimal value if you have not configured an independent domain.
The following is a sample output of the AS path field (depending on your network
configuration, the output might be different):
AS path: [12345] I Unrecognized Attributes: 40 bytes
AS path: Attr flags e0 code 80: 00 09 eb 1a 40 01 01 00 40 02 08 02 03 fd e9 fd e9 01
2d 40 05 04 00 00 00 64 c0
[Routing Protocols]
Support for disabling the attribute set messages on independent AS domains for
BGP loop detection—BGP loop detection for a specific route uses the local autonomous
system (AS) domain for the routing instance. By default, all routing instances belong
to a single primary routing instance domain. Therefore, BGP loop detection uses the
local ASs configured on all of the routing instances. Depending on your network
configuration, this default behavior can cause routes to be looped and hidden.
To limit the local ASs in the primary routing instance, configure an independent AS
domain for a routing instance. Independent domains use the transitive path attribute
128 (attribute set) messages to tunnel the independent domain's BGP attributes
through the internal BGP (IBGP) core. If you want to configure independent domains
to maintain the independence of local ASs in the routing instance and perform BGP
loop detection only for the specified local ASs in the routing instance, disable attribute
set messages on the independent domain. To disable attribute set messages, include
the
independent-domain no-attrset

NAT-PT with DNS ALG support (M Series and T Series routers)—You can configure
Domain Name Service (DNS) application-level gateways (ALGs) using NAT with
protocol translation (NAT-PT) for IPv6 to IPv4. The implementation is described in
RFC 2766 and RFC 2694.
