Denied ICMP no matching session

[Taro-AB81]

Hi All,

I have this MPLS router connected to our ASA Firewall. So My MPLS router interface is 10.30.2.254 and ASA Interface is 10.30.2.1. From my MPLS router im able to ping to 10.30.2.1, but when ping from ASA to 10.30.2.254 i get ICMP denied msg) (denied ICMP no matching session)

Have anyone come across this issue?

 - This may be related to MPLS based security features on   your MPLS router, check if this  hampers basic and or intended functionality or not.

If the error message includes this "denied ICMP no matching session" then it sounds more like an ASA issue than an MPLS issue. Have you enabled inspection for ICMP?
