Configuration example of inter-AS MPLS TE tunnel using
RSVP-TE
Network requirements
Router A and Router B are in AS 100, and they run OSPF as the IGP. Router C and Router D are in AS
200, and they run OSPF as the IGP.
Establish an EBGP connection between ASBRs Router B and Router C. Redistribute BGP routes into OSPF
and OSPF routes into BGP, so that a route is available between AS 100 and AS 200.
Establish an MPLS TE tunnel between Router A and Router D by using RSVP-TE, with the bandwidth being
2000 kbps.
Along the tunnel, the maximum link bandwidth is 10000 kbps and maximum reservable bandwidth is
5000 kbps.

Configuration procedure
1. Assign IP addresses and masks to interfaces (see Figure 26 )
2. Configure OSPF to advertise routes within the ASs
# Configure OSPF on Router A.
