9.9.9.9 not taking DNS traffic over PCH through DE-CIX in Dallas
by Eric C. Miller 15 Aug '25

15 Aug '25

A mouthful, but we're seeing an issue where we can ping 9.9.9.9 but not get response to UDP/53 dns queries. Filtering the prefix 9.9.9.0/24 and taking transports seems to run fine. We're also seeing TCP Resets on SecureDNS. Anyone else seeing something similar? Eric

LAG/ECMP and 'exact-route'
by Saku Ytti 15 Aug '25

15 Aug '25

Hey-o, Which platform/software has a command to show which interface will be used for forwarding with given keys? ASR9k has a cef exec-route, and I see references to this in c-nsp, reddit and cisco.com forums, stressing how useful debugging tool it has been. Despite it not actually working, since it's just RE software, it doesn't talk to the EZchip/lightspeed, unless it has been fixed in the past couple of years, certainly hasn't worked in the timeline of various forums finding it useful. MX has 'jsim' https://www.juniper.net/documentation/en_US/day-one-books/TW_MX3D_PacketWal… which I think actually works, but it is quite involved. I have some (false?) memory that I saw in some release note this being a bit more productised into CLI command, but I'm failing to find anything to support this memory. There is also RFC5837, which is actually implemented in QFX5k, but not for TTL exceeded, we've opened ER to get it supported on MX and PTX and for TTL exceeded. This RFC will allow programmatic platform agnostic discovery of the actual interface used, without relying on platform specific magic. So please do ask your vendors to implement it. -- ++ytti
