CRS-1 support EoMPLS preferred tunnel selection ?

mtiger · ‎01-11-2009

Can anyone help me verify the CRS-1 support EoMpls Tunnel selection function ? or this function is only on the Cisco 12000 router ?

IOS-XR configuration guide 3.6 : have this function , I do not find any restriction.

I check IOS-XR 3.7 config guide, it say :

http://www.cisco.com/en/US/docs/ios_xr_sw/iosxr_r3.7/mpls/configuration/guide/gc37te.html#wp1325561

The following PBTS functions are supported only on the Cisco XR 12000 Series Router:

*L2VPN preferred path selection lets traffic be directed to a particular

TE tunnel.

So , I am not sure CRS-1 support it or not?

Thanks for your help.

Hello Michael,

it says:

>>>The following PBTS functions are supported only on the Cisco XR 12000 Series Router:

â€¢L2VPN preferred path selection lets traffic be directed to a particular TE tunnel.

â€¢Both Interior Gateway Protocol (IGP) and Label Distribution Protocol (LDP) paths are used as the default path for all traffic that belongs to a class that is not configured on the TE tunnels.

â€¢According to the quality-of-service (QoS) policy, tunnel selection is based on the outgoing experimental (EXP) value and the remarked EXP value.

â€¢IPv6 traffic for both 6VPE and 6PE scenarios are supported.

My understanding is that the feature is not supported on CRS-1

Hope to help
