MPLS Tunnel

I would like to understand the concept of Cisco MPLS Tunnels comparing to Huawei Tunnels.

Huawei way:

1. User configures tunnel-interface which describes interface itself and unidirectional tunnel which starts on this interface. All attributes of the Interface and Tunnel are configured here. For example bandwidth, hold priority, setup priority and especially signal type which can be rsvp-te or sr-te.

This tunnel can use one LSP (Working) or two LSPs (Working and Protection)

2. As the next step user configures kind of a tunnel trail which can be:

- unidirectional and uses one tunnel-interface

- bidirectional and uses two tunnel-interfaces in opposite directions

 

How is it working in Cisco ? Is there any document how to configure tunnel interface, signal type, tunnel ?

Hi @Mesho7 ,

 

with Cisco products you have many platforms that support MPLS-TE, so you can start to read at very begin how it works under IOS-XE:

https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/mp_te_path_setup/configuration/xe-16-11/mp-te-path-setup-xe-16-11-book/read-me-first.html

 

 

and then you can give a shot about IOS XR too which is a platform strictly used within ISP environment:

https://www.cisco.com/c/en/us/td/docs/routers/asr9000/software/asr9k-r6-5/mpls/configuration/guide/b-mpls-cg-asr9000-65x/b-mpls-cg-asr9000-65x_chapter_0110.html

 

you can find configuration examples along wih theory behind it.

 

 

kind regards,
