  Are the 9300s doing any routing or are they just L2 switches ?    And if they are just L2 are both 9500s using the same vlan (vlan 82) to peer with their equivalent provider router ?    Finally (for the moment !) which interface(s) did you apply delay to ?    Apologies for all the questions but still trying to work out the topology.    Jon     ...

  STP should not shut the port down, it should just block unless you have something configured incorrectly.    Jon ... View more

  If the interconnects between your distribution switches are L2 trunks then yes STP will block one of the uplinks from your access switch which is exactly what you want otherwise you have a loop.    Note if you are running a per vlan STP version it will block per vlan so you can use both uplinks but only uplink per vlan.    If the interconnects are L3 then no it won't block as long as you do not have the vlans on the access switch on other access switches.    Jon ...

  Apologies for the delay in replying, been a bit busy.    You should be able to use delay or if not use an offset list to choose the routes you want to use,  it is just a question of working out where to apply the configuration   As the 9300s are interconnected is the path from the 9500 direct to the LTE 9300 and then the LTE router or is to the MPLS 9300 , then the LTE 9300 and then the LTE router ?    In addition are you using the same vlan to connect to both 9300s from the 9500 ?    Jon ...

  It depends on what was setup before with the 6500.    What were the connections before between the switches ?    Jon ... View more

  L3 etherchannels are L3 links so they do not propagate vlan information.    You would have different vlans/IP subnets on each set of switches and you would route between them.    Jon ... View more

  Probably going need to a quick schematic with some IPs showing the layout.    Also can you pick just one route that you want reached via MPLS and show the route entries and topology entry off each switch.    Jon ... View more

  Sorry, forgot the obvious one.    What do the routing and EIGRP topology tables show ?    Jon ... View more

  Not really a lot to go on.    Are you using BGP for MPLS and redistributing into EIGRP ?    What are you doing across the backup link in terms of routing ?    Jon ... View more

  Yes, that makes sense if you are going to be moving a lot of traffic in and out of the lab environment.    As long as there is a defined L3 boundary between your lab and your production environment you should be fine.    Jon ... View more

  You only need a route if the default route does not use the same interface you applied the crypto map to.    If you are not seeing any debug output at all then it is either this or your traffic is not being seen as interesting traffic eg. it is being translated to a different IP(s) before the crypto acl is checked.    Jon ...
