It appears there is some type of rate limiting for icmp time-exceeded messages. Is it possible to configure this?
lines 2, 3, and 4 are extreme switches x460/480, a traceroute:

Is there a guide to setting up RA Guard? I thought I saw one once, but I can't find it now. It doesn't seem to be covered in the 15.3 concepts guide, and I can't find a newer concepts guide (getting 404 page not found errors).
I've got 460-24t switches claiming they have 1gb of RAM, and 460-48t claiming they have 512mb. Is this normal, and if so, why do the "bigger" switches have less RAM?
I can't find an official spec sheet anywhere that lists the RAM.
It should be noted that you need to specify the address family with several other commands as well, i.e.:
show bgp nei x❌x::x ipv6-uni tr all
and not
show bgp nei x❌x::x tr all
which will appear to work, but you won't see your routes.
I'll add that on a 480 with full internet routes from multiple providers, changing a policy caused it to go to 50% cpu (presumably the 480 has two cores?) for about 20 to 40 minutes, as it worked through applying the policy change and propogating it ...
This problem happened to us on Summit 480/460. We have opened several TAC cases over it, it is not resolved.
We have found:
The more BGP routes you have, the more likely it is to occur.
The more BGP peers you have (such as if the switch is serving...
