We are facing weird problem on our MX450's on WAN2 interface at DC.
We had configrued MPLS ranges(Private subnets) on MX450(Primary & Secondary) as /28 subnet.
MPLS provider give us the one Loop back IP address which is there in MPLS mesh and asked us to ping to make sure reachability is there or not, but unfortunately we are not able ping the Loopback and also not able to ping MX450 gateway(which is service provider MPLS router)- which is directly connected.
Good to know is that the trace is working...trace is completing for Loopback and Gateway but Ping is not happening
and there is no ACL's configured.
We have same setup for our DR site(only difference is here we use MX250's), where we were abel to ping loopback and ofcourse MX250-Gateway which is service provider rouer IP.
Only the differenece is our DC MX450's has BEta version(17.3) and DR version is 15.44 ?
Did anyone face this kind of ping problem.? please guide me what may be the problem?
