IOS-XR accepts extended communities and large communities by default.
You have to enable to send them, but not receive.

Thanks for setting me straight.
I had heard that there was some new stuff with Linux hypervisors or something
like that…. So I misspoke.

I guess he never saw a Juniper M40, it's literally an i686/x86 32-bit
motherboard for the routine engine, glued to a chassis with linecards
containing custom ASICs and optics. As I recall it was a moderate speed
Pentium 2 with some average amount of RAM and a 2.5" 44pin ATA66 laptop
hard drive.

Google around for Junos Evolution. Junos is going native Linux.

Above all, JUNOS makes sense when configuring, you literally the software
gives you the feel of talking to the device. If your brain is programmed to
be logically then all pieces and modes easily come to life and adaptation
becomes a zero hustle.

Yeah, it changes.

Right, it's been freebsd forever as I understand it, but I thought there had
been some more recent involvement with linux, which is why I said that. I'm
not an authority on it though.

I will say that so far I'm finding JunOS and the Juniper documentation to
be a welcome change. In my other life I write networking/IoT code and
have done my fair share of unix (linux, freebsd, sunos, etc.)
administration over the years. As a result, JunOS is feeling more natural
than some device

If you are an OSPF shop, Cisco AD is 110 for internal and external
routes. Juniper is 10 for internal and 150 for external. This can be
changed via an export (maybe import) policy on the OSPF protocol.
