Configuring an I-SID List for an IPv6 IS-IS Accept Policy
Configures a list of I-SID numbers that represent local or remote Layer 3 VSNs to which the IPv6 IS-IS accept policy applies. After you create the list of I-SID numbers, you must then create, configure, and enable the IPv6 IS-IS accept policy.

Note
When creating an I-SID list, you can add I-SID entries until the maximum limit for supported Layer 3 I-SIDs is reached. The system truncates any additional I-SID entries. The maximum limit includes the I-SIDs for locally configured Layer 3 VSNs and the I-SIDs specified for IS-IS accept policy filters.
Refresh the EDM tab to view the actual list of I-SIDs in the I-SID list.
Before you begin
- 
                    Enable IS-IS globally. 
- 
                    Ensure the manual area exists. 
- 
                    Change the VRF instance as required to configure an I-SID list for an IPv6 IS-IS accept policy on a specific VRF instance. Not all parameters are configurable on non-default VRFs. 
Procedure
- In the navigation pane, expand .
- Click IS-IS.
- Click the Isid-List tab.
- Click Insert.
- In the Name field, specify a name for the I-SID list.
- Select Isid or Isid-List.
- Specify an I-SID number or a list of I-SID numbers.
- Click Insert.
- Click Apply.
Isid-List Field Descriptions
Use the data in the following table to configure the Isid-List tab.
| Name | Description | 
|---|---|
| Name | Specifies the name of the I-SID list. | 
| Isid | Specifies a particular I-SID number or a list of I-SID numbers that represent local or remote Layer 3 VSNs to which the IPv6 IS-IS accept policy applies. An I-SID value of 0 represents the global routing table (GRT). |
