4000 Router Series MPLS Configuration Guide

Establishing an inter-AS MPLS TE tunnel with RSVP-TE

Network requirements

Router A and Router B are in AS 100. Router C and Router D are in AS 200. AS 100 and AS 200 use

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 AS 100 and AS 200 can reach each other.

Establish an MPLS TE tunnel from Router A to Router D. The tunnel requires a bandwidth of 2000 kbps.

The maximum bandwidth of the link that the tunnel traverses is 10000 kbps, and the maximum reservable

bandwidth of the link is 5000 kbps.

Configuration procedure

1. Configure IP addresses and masks for interfaces. (Details not shown.)

2. Configure OSPF to advertise routes within the ASs, and redistribute the direct and BGP routes into

OSPF on Router B and Router C:

# Configure Router A.

<RouterA> system-view

[RouterA] ospf

[RouterA-ospf-1] area 0

[RouterA-ospf-1-area-0.0.0.0] network 10.1.1.0 0.0.0.255

[RouterA-ospf-1-area-0.0.0.0] network 1.1.1.9 0.0.0.0

[RouterA-ospf-1-area-0.0.0.0] quit

[RouterA-ospf-1] quit

# Configure Router B.

<RouterB> system-view
