Hello @sjrcoel,
Regarding your configuration:
interface tunnel-te401
- This command creates a tunnel interface with the name "tunnel-te401".
-`ipv4 unnumbered Loopback0` indicates that the tunnel interface will use the IPv4 address assigned to Loopback0 as its source IP address.
- `load-interval 30` sets the load interval to 30 seconds.
- `autoroute announce` enables the automatic announcement of the tunnel to other routers.
destination 178.25.51.225
- This command specifies the destination IP address (178.25.51.225) for the tunnel.
- `fast-reroute protect node` configures fast reroute protection at the node level.
- `record-route` instructs the router to record the path the traffic takes in the tunnel.
path-option 1 dynamic ospf 10 area 330
- This command defines a dynamic path option (path-option 1) for the tunnel.
- It specifies that OSPF with process ID 10 and area 330 will be used to determine the path for the tunnel.
mpls traffic-eng
- This command enters MPLS Traffic Engineering configuration mode.
interface TenGigE0/1/0/10', 'interface TenGigE0/3/0/2.330', 'interface TenGigE0/3/0/3.330', 'interface TenGigE0/4/0/2.330', 'interface TenGigE0/4/0/3.330
- These commands configure specific interfaces, indicating that they are candidates for auto-tunnel backup.
-->Your configuration sets up an MPLS-TE tunnel interface named "tunnel-te401." The tunnel uses Loopback0 as the source IP address and has fast reroute protection, automatic route announcements, and a dynamic path option determined by OSPF in area 330. Several interface are configured as candidate for auto-tunnel backup, which can be used as backup paths for the MPLS-TE tunnel.
