Because you may not have an option, if you're IPv6 only, vendors (e.g.
junos) may expect you to punch i

The group rate of $250 USD/night is full and no longer available.
Online availability is $355 USD/night.
But if you call, wait on hold, and ask for the AAA discount, the rate is $305
USD/night.
Thought I would share as it may help others save a little money.

arbitrary 32 bit number unique in the autonomous system. even in an

Right!
Personally it just needs to be unique. Relying on a Id to be unique when
ascociated to an IP address that may be used on a failover system seems really
poor to me.
Assign a random ID and plug it into your IPAM!. If at anything assign a router
ID to a rack location and associate every bi
Is there really such as thing as pure IPV6 only? I don’t think you will be able
to run IPV6 for transport without the router locally knowing how to handle
IPV4, at least not right now as there’s a lot of legacy code. Usually IPV6 is
enabled longer after IPV4 has been running. With that said, can

In response to feedback from operational security communities,
CAIDA's source address validation measurement project
(https://spoofer.caida.org) is automatically generating monthly
reports of ASes originating prefixes in BGP for systems from which
we received packets with a spoofed source address.

the uniqueness is supposed to be on the tuple {AS,RID}
so an RID 'collision' with a foreign AS should not be possible
