Notice that running router will show assigned MPLS lables, whole tunnel path and reserved bandwidth. Secondary-paths=dyn record-route=yes from-address=10.255.0.3 Secondary-paths=dyn record-route=yes from-address=10.255.0.1 Since our primary goal is to strictly forward traffic over specific path we will use static path configuration as primary, and dynamic (CSPF) as secondary path if primary fails. Since we are not using real bandwidth limitation on the tunnels in this example, bandwidth parameter is only used for administrative purposes and can be any value (it does not represent how much bandwidth will actually flow through the interface). Next step is to set up TE resource for every interface on which we might want to run TE tunnel.Ĭonfiguration on all the routers are the same: Set default router-id=10.255.0.4 mpls-te-area=backbone mpls-te-router-id=LoopbackĪfter OSPF is set up verify that we have correct routing information in routing table of each /ip route> printįlags: X - disabled, A - active, D - dynamic,Ĭ - connect, S - static, r - rip, b - bgp, o - ospf, m - mme,ī - blackhole, U - unreachable, P - prohibitĥ ADC 192.168.10.0/30 192.168.10.1 ether3 0Ħ ADC 192.168.33.0/30 192.168.33.1 ether1 0ĩ ADC 192.168.33.12/30 192.168.33.14 ether2 0 Set default router-id=10.255.0.3 mpls-te-area=backbone mpls-te-router-id=Loopback Set default router-id=10.255.0.2 mpls-te-area=backbone mpls-te-router-id=Loopback Set default router-id=10.255.0.1 mpls-te-area=backbone mpls-te-router-id=LoopbackĪdd network=192.168.33.0/24 area=backbone To successfully complete the setup we need loopback reachability information on every router.ĬSPF will also be configured (extension of OSPF) to carry TE reservation information. In this setup we will use OSPF dynamic routing protocol to distribute routing information between routers. Loopback address reachability and CSPF setup
