Configuration Example Of Inter-As Mpls Te Tunnel Using Rsvp-Te - H3C SR8800 10G Mpls Configuration Manual

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.
