Hi all
I have configured MPLS TE with RSVP using ISIS inside the MPLS core
R2 and R4 are my PE routers
R2#sh run int tun0
Building configuration...
Current configuration : 259 bytes
!
interface Tunnel0
ip unnumbered Loopback0
tunnel mode mpls traffic-eng
tunnel destination 4.4.4.4
tunnel mpls traffic-eng autoroute announce
tunnel mpls traffic-eng path-option 1 explicit name PATH
tunnel mpls traffic-eng path-option 2 dynamic
end
R4#sh run int tun 0
Building configuration...
Current configuration : 259 bytes
!
interface Tunnel0
ip unnumbered Loopback0
tunnel mode mpls traffic-eng
tunnel destination 2.2.2.2
tunnel mpls traffic-eng autoroute announce
tunnel mpls traffic-eng path-option 1 explicit name PATH
tunnel mpls traffic-eng path-option 2 dynamic
end
Now , the explicit path is working fine , when I shutdown one of the links
across the MPLS backbone , the tunnel interfaces become up again due to the
dynamic path configured under the tunnel interface
Now , when I remove the dynamic and configure FRR instead , the tunnel
interface keep in the down state (it's line protocol)
tunnel mpls traffic-eng fast-reroute bw-protect
Am i missing something ?
BR,
