New and Changed Segment Routing Features
Segment Routing Features Added or Modified in IOS XR Release 7.3.x
| Feature | Description | Introduced/Changed in Release | Where Documented |
|---|---|---|---|
|
BGP Best Path Computation using SR Policy Paths |
BGP selects the best path from the available pool of paths such as iBGP, eBGP, color, or noncolor paths with native next hop and SR policy next hop. BGP uses either native next hop or an SR policy next hop for best path computation. |
Release 7.3.4 |
|
|
Improved Segment List Information for Inactive or Invalid Policies |
This feature provides for displaying detailed segment list information, and also lists information on invalid and inactive policies. This allows you to determine if the policies have been received correctly, to the SR-TE policies with explicit path. |
