[c-nsp] MPLS TE conver from IOS to IOS-XR

[Oliver Boehmer (oboehmer)]

Hu,

 

you indeed want to configure 

 

rsvp

interface ..

   bandwidth …

 

in order to be able to use non-zero banwdith reservations. That’s part of your basic MPLS-TE config, which I didn’t include in my config example.. 

By default, the bandwidth is zero on interfaces enabled for MPLS-TE (i.e. the ones enabled under “mpls traffic-eng”)..

The MPLS TE signaling usually uses the RSVP, but in the global configuration i didn't see any RSVP configuration, why? Is the the default configuraion? 

 

Many thanks.

ok.. you can also leave out the “autoroute-announce” for the beginning, then the tunnel won’t take any traffic and you will be able to check if everything is set up correctly (i.e. the primary/mesh tunnels are being built and the backups are being installed), without any impact to the live traffic..

you need to configure autoroute-announce and attribute-set, which you in turn reference in the group..  look at the "autoroute announce" in the config I sent.
As far as I know, path-option is always dynamic for auto-tunnel mesh in XR, so no need to configure this.
