ping u.u.u ??

[briansciarra]

Hey,

I recently got fios at a branch to facilitate a backup circuit (dmvpn over bgp)

I am plugging my cisco 2911 directly into the Ethernet port of the ONT, which looks like a modem that converts fiber to ethernet

When I do that, when I try to ping the interface on my router that is plugged into the ONT, and I get a response 'U.U.U'

Not sure what to make of this

I can ping my gateway so that's promising

If I pull the cable out of the interface, I can ping the interface but not my gateway.

I can't failover test for a couple days but just curious does anyone know what U.U.U means?  I'm ssh'd into the router that I'm pinging the interface of so it should just work.

Thanks!

Chaque « U » signifie qu’un paquet « destination inaccessible » a été recu.

U : Unreachable

Agree that the U indicates Unreachable. The reason that there are 3 U and not 5 U is due to rate limiting on the ICMP responses.
