Hey just trying to get a feel for this in a lab, it appears that I cannot get my TE tunnel to come up. I have the tunnel configured for MPLS TE, traffic eng tunnels configured globally and under all interfaces in the path, and ip rsvp bandwidth configured under the interfaces in the path. I am running OSPF with the proper commands. I have my ospf routes on the tunnel endpoints, the tunnel destinations in OSPF as well as the MPLS forwarding table, however when I try to show the mpls tunnel it says no path to the endpoint. The one place I was concentrating was the RSVP setup as from my understanding it need to use this signalling to form the LSP tunnel. It would appear that my RSVP is not working as I show nothing when I do any of the show commands to see the RSVP paths. Any help is welcome on how to troubleshoot the RSVP. One thing is I have frame-relay subinterfaces, do I need to put the ip rsvp bandwidth command under the main interface also?
So without outputs from your routers its tough to troubleshoot, but here is all you need to configure a tunnel. Also, "show mpls traffic topology" is a good place to start.
R1 -- R2 -- R3
TE start/end node: R1 and R3
!!TE extensions only share info within an area, so a requirement is that the tail node be in the same ospf area as the head node.
Also, the default settings for rsvp restrict a flow to 1,000K, so make sure if you are trying to setup a tunnel with more the 1,000K, that your path will support a reservation that big. The example below allows a single flow to use all 10,000K for single tunnel.
thats pretty darn close to what I have. I agree on the tunnel bandwidth command if I fat fingered it and tried to reserve say 100mb instead of 10mb and my lowest link was reserved at 45mb the tunnel would not come up correct? That is the only thing I can think of.
