AT&TMPLS Issues?

  • From: Elijah Savage
  • Date: Sat Dec 17 14:56:25 2005


All,

I had about 20 customer down today which connect back to me via vpn connectivity across the internet, but we also have a private Sprint MPLS conection that was down at this time. My VPN tunnels all started to come up at about 2:20pm today at the same time and at exactly that time my private Sprint MPLS connectivity came back up which was weird. Below you will find traceroutes that stops in Sprints address space but then after it all came back up the very next hop is AT&TMPLS. I then did some correlation and found out that all my tunnels that were down the peering address belongs to AT&T all were 12.x addresses. Were there some sort of routing issue between AT&T and Sprint between Noon and 2:30 today? I do not peer with AT&T or Sprint so I am sure they will not give me any info if I called in. But I do have a ticket open with my provider to see if they can get info out of them.
