I noticed that too Jon, I think its just a display thing - because it's
saying the interface name it also shows the mac..

Actually, it could also be an ingress filter on their side (no other packets
will be routed across 10g link except the icmp request when doing locally).

I think the problem is an egress filter on level3 side of 10g. It has to

When pinging from 10g interface local .14<->remote .13, icmp response
packets will certainly come back over 10g as router on level3 side will be
using connected route. *not working*
When pinging from host to remote .13,

Have they correctly set their end of the link - does the IP address actually

Hi,

Correct, I am just trying to get it to where I can ping it first (which is what
I usually do, anyway).
Ah...but when you do this, are you sure x.x.x.13 is really the other side

TTL-based filtering, perhaps?
Though you (nor anyone else) shouldn't be able to ping any of their routers at
all, IMHO.

Howdy,
I currently have two connections to Level3 because I am upgrading, one (the old
one) is a 1Gbps connection in Router-1, the second one is a 10Gbps connection
in Router-2.
Both connections are up/up, the old connection is getting a full BGP session
from Level3.
I noticed that no matter
