Configuring IPv6 IS-IS link cost
Configuring an IPv6 IS-IS cost for an interface
Step | Command | Remarks |
---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter IS-IS view. | isis [ process-id ] [ vpn-instance vpn-instance-name ] | N/A |
3. Specify an IS-IS cost style. | cost-style { narrow | wide | wide-compatible | { compatible | narrow-compatible } [ relax-spf-limit ] } | By default, the IS-IS cost type is narrow. |
4. Enter IPv6 address family view. | address-family ipv6 [ unicast ] | N/A |
5. Enable IPv6 IS-IS MTR. | multi-topology [ compatible ] | By default, IPv6 IS-IS MTR is disabled. |
6. Return to IS-IS view. | quit | N/A |
7. Return to system view. | quit | N/A |
8. Enter interface view. | interface interface-type interface-number | N/A |
9. Enable IPv6 for IS-IS on the interface. | isis ipv6 enable [ process-id ] | By default, IPv6 is disabled for IS-IS on an interface. |
10. Specify an IPv6 cost for the IS-IS interface. | isis ipv6 cost | By default, no IPv6 cost is specified for the interface. |
Configuring a global IPv6 IS-IS cost
Step | Command | Remarks |
---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter IS-IS view. | isis [ process-id ] [ vpn-instance vpn-instance-name ] | N/A |
3. Specify an IS-IS cost style. | cost-style { wide | wide-compatible | compatible } | By default, the IS-IS cost style is narrow. |
4. Enter IPv6 address family view. | address-family ipv6 [ unicast ] | N/A |
5. Enable IPv6 IS-IS MTR. | multi-topology [ compatible ] | By default, IPv6 IS-IS MTR is disabled. |
6. Specify a global IPv6 IS-IS cost. | circuit-cost cost-value [ level-1 | level-2 ] | By default, no global IPv6 cost is specified. |
