SR-TE policy commands
address-family ipv4 sr-policy
Use address-family ipv4 sr-policy to create the BGP IPv4 SR-TE policy address family and enter its view, or enter the view of the existing BGP IPv4 SR-TE policy address family.
Use undo address-family ipv4 sr-policy to delete the BGP IPv4 SR-TE policy address family and all the configuration in the BGP IPv4 SR-TE policy address family.
Syntax
address-family ipv4 sr-policy
undo address-family ipv4 sr-policy
Default
The BGP IPv4 SR-TE policy address family does not exist.
Views
BGP instance view
Predefined user roles
network-admin
Usage guidelines
The configuration in BGP IPv4 SR-TE policy address family view applies only to routes and peers in the BGP IPv4 SR-TE policy address family.
Examples
# In BGP instance view, create the BGP IPv4 SR-TE policy address family and enter its view.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp-default] address-family ipv4 sr-policy

binding-sid
Use binding-sid to configure an BSID for an SR-TE policy.
Use undo binding-sid to delete the BSID.
Syntax
binding-sid mpls mpls-label
undo binding-sid
Default
No BSID is configured for an SR-TE policy.
Views
SR-TE policy view
Predefined user roles
network-admin
Parameters
mpls mpls-label: Specifies the BSID value, which is an MPLS label value in the range of 16 to 1048575.
Usage guidelines
You can use this command to manually configure a BSID for an SR-TE policy or leave the SR-TE policy to obtain a BSID automatically. If an SR-TE policy has only color and endpoint configuration, the SR-TE policy will automatically request a BSID.
The manually configured BSID has a higher priority over the automatically obtained BSID.
If you configure an MPLS label as the BSID but the label is not in the range of the SRGB or SRLB or is already used by a protocol, the configuration does not take effect. For more information about SRGB or SRLB, see MPLS SR configuration in Segment Routing Configuration Guide.
If you execute this command multiple times, the most recent configuration takes effect.
The candidate paths of the same SR-TE policy have the same BSID.
Examples
# Set the BSID of SR-TE policy srpolicy to 20.

|
Reason |
Description |
|
preferred-value |
Routes with larger preferred values exist. |
|
local-preference |
Routes with larger local preference values exist. |
|
as-path |
Routes with smaller AS_PATH attribute values exist. |
|
origin |
There are routes whose origin has a higher priority. The route origins are IGP, EGP, and INCOMPLETE in descending order of priority. |
|
med |
Routes with smaller MED values exist. |
|
remote-route |
There are routes whose remote-route attribute has a higher priority. BGP selects the optimal route from remote routes in this order: · Route learned from an EBGP peer. · Route learned from a confederation EBGP peer. · Route learned from a confederation IBGP peer. · Route learned from an IBGP peer. |
|
igp-cost |
Routes with smaller IGP metrics exist. |
|

|
rfc5004 |
A route received from an EBGP peer is the current optimal route. BGP does not change the optimal route when it receives routes from other EBGP peers. |
|
router-id |
Routes with smaller router IDs exist. If one of the routes is advertised by a route reflector, BGP compares the ORIGINATOR_ID of the route with the router IDs of other routes. Then, BGP selects the route with the smallest ID as the optimal route. |
|
cluster-list |
Routes with smaller CLUSTER_LIST attribute values exist. |
|
peer-address |
Routes advertised by peers with lower IP addresses exist. |
|
received |

display segment-routing te policy
explicit segment-list
Use explicit segment-list to specify an SID list for a candidate path.
Use undo explicit segment-list to delete an SID list of a candidate path.
Syntax
explicit segment-list segment-list-name [ weight weight-value ]
undo explicit segment-list segment-list-name [ weight ]
Default
No SID lists are specified for an SR-TE policy candidate path.
Views

Predefined user roles
network-admin
Parameters
segment-list-name: Specifies an SID list name, a string of 1 to 128 characters.
weight weight-value: Specifies a weight for the SID list, in the range of 1 to 4294967295. The default weight is 1.
Usage guidelines
An SR-TE policy uses the SID list specified for the highest-preference candidate path as a traffic forwarding subpath.
An SR-TE policy candidate path can have multiple SID lists. All the SID lists can be used to forward traffic for load sharing based on their weights. Assume SID lists a, b, and c are assigned weights x, y, z, respectively. The load of SID list a is x/(x+y+z) of the total traffic.
If you assign weight values for the same SID list multiple times, the most recent configuration takes effect.

import-route
Use import-route sr-policy to enable BGP to redistribute routes from the SR-TE policy.
Use undo import-route sr-policy to restore the default.

Usage guidelines
After you execute this command, the system will redistribute the local SR-TE policy routes to the BGP routing table and advertise the routes to peers. Then, the peers can forward traffic based on the SR-TE policy.
Examples
# In BGP SR-TE policy address family view, enable BGP to redistribute routes from the SR-TE policy.
