It's not "somewhat old", Cisco has explicitly declared the RSP-440
end-of-life. The ASR-9006 chassis is still supported.

More seriously - the 'TR' scale and 'SE' scale don't differ in TCAM,
only in their installed RAM. This may matter to you,

I use same router with two copies of full BGP on v4 and v6.
There is a way to mitigate the problem without

My advice is "don't let that happen".
Thanks for the advice and feedback all!
I will set "maximum-prefix" on my sessions, and stop receiving full v6
table and just make a default route for v6. Then I can give more space
to v4 (will require reboot)

Hi,
at least for Sup720-3B(XL) and Sup-2T it results in number 1 for the

So in most cases it will look that way:

Current IPv6 FIB exception state = FALSE
Current MPLS FIB exception state = FALSE

Hi,
I'm currently using a 7606 (RSP720RSP-3CXL) and taking in full BGP on v4
and v6. Obviously it the TCAM is almost full and the box needs to be
replaced.
But a have a couple of questions.
I have been hearing different scenario of what would happen when the
TCAM is full:
